Canteen System Assistance Notes

The leading alert team had apparently met with misfortune.

Some people began to pray to God, some began to sob, and some began to collapse. Captain Wang Liang knew that as a leader, he had to stand up and do something at this moment. Otherwise, once the team collapsed, no one would survive under the pursuit of the bandit cavalry.

But what could they do? There was no terrain to defend, and with a district squad of just over 100 men plus the basic militia, while almost everyone had a gun, they were short on ammunition. Each member of the district squad had only 15 rounds of ammunition, 10 of which were reloaded. The basic militia had only recently been equipped with the Martini rifles left over from the Qing Dynasty. Each man had only 10 rounds of ammunition, and they had even fired three during practice before setting off. The rest of the armed personnel were even carrying red tasseled spears. The supplies they were transporting contained no ammunition, only door panels...

Red tassel spear.....door panel....

Captain Wang turned and glanced at the current team. Three large power-assisted carts formed a triangle, while a wheelbarrow blocked the gap in the large workshop. The door panels on the carts, numbered in red paint, lay quietly. On the enemy side, there were no cannons within sight. The most common weapons they had were rifles. Many of them even carried broadswords, presumably to chop off heads during pursuit.

He suddenly thought of the historical illustration book he saw in the county brigade library.

"Team One, Team Two, Team Three!"

"arrive!"

"Team one, remove the door panels, stick them into the ground, and use men to hold them up! Team two, stick the ash poles diagonally into the ground, with the spear tips facing outward, extending from the middle of the door panels!" "Whatever, let's try this!" Captain Wang ordered quickly and urgently, "Team three, the militia, form a square formation, just like we did during our daily meetings: a hollow square formation, bayonets fixed, bullets loaded!"

"Everyone, attention! No firing without my order!"

The transport team from Ganyu County of the Binhai Military Sub-district distorted themselves, erected a row of shield walls with door panels, held up "spears", and used carts to form an irregular square array. The riflemen inserted bayonets, loaded bullets, and nervously aimed at the bandits outside - the whole team was like a hedgehog with its spikes erected, warily watching the approaching fox.

Liu Heiqi's men were getting closer. Perhaps it was because they were looking for an opportunity, or because this turtle-like formation was difficult to attack, but they didn't attack immediately. Instead, they circled around the transport convoy, slowly reorganizing their formation, as if looking for an opportunity.

When facing cavalry, infantry is always at a natural disadvantage of passive defense, but as a weak force, infantry can also rely on strong will and tight formation to defend, so that the cavalry dare not charge recklessly - if nothing unexpected happens, this will be a battle of wills until the cavalry gives up the attack, or the infantry is exhausted and a flaw appears.

But the "accident" happened after all, and this classic battle never took place.

The radio on the waist of district squad leader Wang Liang made a buzzing sound, and a broadcast-style instruction came from it, ordering the squad that first discovered the enemy to fire a signal flare to "indicate the target for the reinforcements." He took out his signal gun, raised his gun to the sky with his comrades, and fired two signal flares, one red and one green. Not long after, he fired two more.

Soon, a roar that didn't belong to horse hooves could be heard from the horizon. An "Anson" flew out from the heart of Shandong Province. Here, it was not only a trainer aircraft used by the Eighth Route Army to train infiltration crews, but also a very useful light battlefield reconnaissance aircraft, and naturally it could also play a cameo role in ground attack.

It crossed the battlefield, and before the bandits could flee, it started the two modified skars on its head and fired a barrage of bullets at the bandits.

It dropped ten 10-kilogram bomblets into the motley cavalry.

between.

With the sound of the explosion, the battle was declared over, and the evil Liu, who had been a scourge to Shandong and Henan provinces for many years, was wiped out.

Chapter 343: Communist Party Project (I) Yumenkou Yellow River Iron Bridge

From Fushi, the troops continued southward to Tongchuan, then turned east, passing through Pucheng and Chengcheng before turning northeast to reach Hancheng, which had recently been taken over by the Eighth Route Army. From Hancheng, heading east across the Yellow River, they reached the Hejin Triangle, the front line of the War of Resistance.

The Hejin Triangle, the defensive line inherited by the Eighth Route Army from Commander Zhao Shengling, lies within the Fen and Yellow River deltas, marking the transition from the high slopes of the Huangshi Plateau to the flatlands of the Guanzhong and Southern Shanxi basins. The terrain of this area is quite unique. Although situated within the Southern Shanxi basin, the overall terrain shows a continuous, gentle descent from northwest to southeast, with the elevation gradually decreasing.

This unique terrain facilitated the deployment of the defenders. Simply by controlling the Fen River and occupying the northwest side of the slope, they could deny the enemy's line of sight, using their superior strength to defeat the enemy's inferior strength, and using their smaller numbers to defeat their larger numbers. Zhao Shengling, with just over 10,000 men, was able to hold off an entire Japanese division here, leveraging this advantageous terrain. During Zhao Shengling's tenure, the Eighth Route Army collaborated effectively with this Party activist, transporting cement from Fuxian and Tongchuan, and steel from Fushi, to the area. This created a miniature trench defense, helping the 38th Army hold off the Japanese 41st Division. After the February Incident, when the Yumenkou, Hancheng, and Hejin regions were completely under control, this area became a bridgehead for large-scale border crossings into Shanxi Province.

Since it is a bridgehead, there must be a bridge, right? It is always inconvenient to ask the border area to use motorboats to transport people and goods.

The closest ferry crossing to the Hejin area was Yumen Ferry, also known as Longmen Ferry. This was a traditional ferry crossing on the Yellow River, accommodating the 25-ton flat-bottomed shallow-water ferries that the Eighth Route Army was now producing. To protect this vital artery of the Hejin Triangle, the Eighth Route Army deployed valuable Polish Bofors 75mm anti-aircraft guns, 40mm Bofors guns, and water-cooled M2/1921 machine guns, established anti-aircraft positions, and built a frontline airfield in the Hancheng area.

Above the Yumen Ferry, where boats sail, there's a place called "Yumenkou." Although it's located along the Yellow River, it boasts a rocky island and a mountain-linking stone platform over 20 meters above the water. The geology is relatively stable and not easily flooded, making it a rare stable foundation in the Loess Plateau, ideal for bridge construction.

The only problem was the unstoppable flow of the Yellow River. The thick sediments at the riverbed and the annual torrent of drifting ice made it difficult to easily build a solid bridge pier in the center of the river. Even at Yumenkou, where the Yellow River was squeezed between rocky mountains and islands, it was still over 140 meters wide.

But hundreds of miles upstream and downstream, there seemed to be no more suitable place. After several months of investigation by the comrades of the Surveying and Mapping Section of the Capital Construction Engineering Corps, the Eighth Route Army finally decided to build a bridge here.

-—-——---

To build a bridge in a materialistic world, one must prepare materials. Huang Jingzhai, the head of the Central Industrial Commission, first searched through the list of all producible and available materials in the border area.

Compared to the historical situation during the Liberation War, when the Logistics Engineering Department was forced to use wood and wire to construct the Yumenkou pedestrian cable bridge, the border region now boasts structural steel, steel wire, and various rivet fasteners produced by Huinong Steel and Fushi Special Steel. They can source rebar, weathering steel profiles, and the main load-bearing cables for freight elevators from their supplier system. The experienced construction troops also possess tractors and rollers from International Harvester and Caterpillar, single-cylinder tractors assembled and manufactured in the border region, and a six-ton ​​Collis truck crane purchased with British delivery vouchers. They also have a team of construction personnel who are considered among the most experienced in China.

Now that the construction conditions were complete, it was time to find a design firm. After much searching, Huang Jingzhai decisively sought out the Xinzhong Machinery Factory, already established in the border region. This factory not only produced valuable internal and external combustion engines for the region, but its director, Zhi Aizhou, was a steel structure and machinery expert. His team of engineers was not only skilled in manufacturing machinery but also possessed a solid foundation in civil engineering. Many of the bridges on the Zhejiang-Jiangxi Railway, which opened in 137, were the work of this team.

"So what kind of bridge is the border region government planning to build?" Zhi Bingliang, the younger brother of Factory Director Zhi Aizhou and a member of the Republic of China Civil Engineering Party, asked Minister Huang Jingzhai. As a typical contractor, figuring out what the contractor wants is the root of every project. "Is it a pedestrian bridge, or one for trucks?"

"We are planning to build a carriage bridge. You see, the border area already has these supplies in stock."

Huang Jingzhai was a relatively new client, so he was quite cautious when it came to such professional scientific issues. "Using these cables, structural steel, and concrete, do you think it would be difficult to build a bridge that can accommodate pedestrians, horses, and carts? If it's really difficult to produce them ourselves, we can import them."

"Once this bridge is completed, we will prepare a railway bridge to match the long-term cross-Yellow River railway plan."

Zhi Aizhou and Zhi Bingliang began to study the Eighth Route Army's requirements. Honestly, these requirements were a bit conservative. The central government's desired outcome was nothing more than a cable-stayed bridge using cables and movable decks, capable of carrying at most fully loaded power-assisted trucks. After all, this was a Yellow River bridge, not a railway bridge like the Wuding River, where piers could be sunk and bailey beams and trusses laid.

"Um... Border Region Government, um... Mr. Huang, I actually have an opinion." Zhi Aizhou raised his head from the pile of documents, "Our government is ready to spend money to repair the bridge.

Since we are planning to build a 2-ton load capacity, why not spend a little more money and build a 5-ton load capacity?

Tons of load, right? Actually, there is no difference between the two.

"Or, why not just spend a little more money and build a suspension bridge instead of a cable-stayed one? Trucks can drive across it, and it can even pull artillery! Then we can use trains on the railway bridge and trucks on the highway bridge. What do you think?"

Building a bridge across the Yellow River was a rather difficult task in that era.

While not as powerful as the Yangtze River, only two fixed "bridges" existed across the Yellow River at that time, in Jincheng and Zhengxian. The rest were floating bridges. But given the vastly superior supply of materials and construction teams available in China at the time, would building a 140-meter single-span bridge really be a particularly difficult undertaking for China's civil engineering bridge and tunnel companies?

Obviously not. Even in such a bad environment as the Republic of China, domestic civil engineers still created many excellent works in bridge construction.

With the honor of being the third Yellow River Bridge and the first Communist Party Bridge, coupled with a generous budget, guaranteed supplies, and a client who respected science, the Xinzhong Factory design team, motivated by so many factors, began their own battle. They quickly established a design and construction office in Hancheng, sent one complex calculation request after another to the magical "Mr. Raspberry," and began drawing on the drawing board, planning the entire construction process.

Meanwhile, the Eighth Route Army's construction engineering corps, which had begun advance preparations, brought in trucks, bulldozers, and tamping machines. They used mortars to fire a dragline across the river, erected a material ropeway and a temporary bridge for personnel, and began the rumbling work of land leveling, construction planning, and material storage. Furthermore, given the wartime environment, the engineering team also organized air defense drills and evacuation plan rehearsals for the workers to prevent damage to the construction site should Japanese aircraft break through interceptor and air defense positions.

But at this moment, a plane slowly flew into the Gaojing Airport, and a middle-aged man wearing glasses got out. He brought a group of people, carrying suitcases, and rushed to the Eighth Route Army Infrastructure Engineering Department in Gaojing City by car, and rushed into Huang Jingzhai's office in a hurry.

"My name is Qian Changgan, and I'm a bridge designer."

He introduced himself briefly, "I have recently heard in the bridge industry that your party is preparing to build a new Yellow River Bridge and has all the materials, manpower and machinery. I am extremely excited.

While this may seem like a case of intellectual disdain, like Wang Po boasting about melons, Xinzhong Company's specialty is load-bearing railway bridges with straight-cable trusses and steel-concrete piers. A pier-less suspension bridge spanning 140 meters across the Yellow River wouldn't actually require such significant costs and man-hours. At this critical moment of national crisis, wasting strategic resources like steel and cement is truly a waste... Those cement and cables would be better used elsewhere to generate valuable benefits.

"If I were to participate in the bidding, we could probably keep the budget and construction schedule the same and increase the capacity to 10 metric tons!"

"ah?? ?"

Chapter 344: Communist Project (II) Liyang Aircraft Factory

At the end of August 1940, one day after the Battle of Zhongtiao Mountain, four "Donkey" fighters flew past their own positions at high speed. One of them seemed to be damaged, with a faint black smoke, but its flight posture did not seem to have changed much, so the damage was not serious.

"Ma Tuan 02, look down there." The lead pilot, Ma Tuan 01, pressed the intercom button. "The army comrades are greeting us." "Ah, yes! The army comrades are so happy! We'll ask them to capture the Japanese pilots later!"

The still intact aircraft flapped its wings, displaying its "Red Star with Chinese Characters" emblem and blue and white striped rudder identification pattern to the friendly positions below, drawing cheers from its comrades below. They tossed their hats and helmets into the air, leaping for joy and celebrating the air warriors' victory.

Today, the four Type 16s on duty encountered the enemy during patrol, shooting down two more sneaky Type 95 reconnaissance aircraft. Although the two wingmen in this combat team were relatively new, one of them mishandled the attack and was wounded by a volley of 7.7mm bullets fired by the enemy reconnaissance aircraft. However, the experienced lead pilot quickly seized the opportunity and dispatched the enemy with a barrage of bullets.

This kind of low-intensity combat was good for training new pilots, but if we had seen the high-intensity dogfight a few days ago, it would have been a bit inappropriate to have newcomers participate. "Ma Tuan 01," the patrol team leader, recalled that day's battle.

At the time, the 96th Army, responsible for the rearguard, was still desperately trying to escape the Eighth Route Army's guerrilla zone, heading for the Eighth Route Army's actual control zone. Seeing that the enemy troops were outpacing them, the Japanese assembled a "large group" of 12 aircraft. Eight Type 97 fighters and four Type 97 light bombers from the 3rd Air Division took off from Jinyang City and headed south, intending to attack the exhausted 96th Army.

Next, the Eighth Route Army Air Force, which received an air situation warning from the Air Defense Command, made an emergency move and launched two squadrons of 24 fighter planes from Hejin and Hancheng areas: one fighter plane after another took off from the left bank of the Yellow River, assembled into a formation, and after flying over the Yellow River, crossed the Fen River like cavalry, and rushed towards the Japanese aircraft group without hesitation.

That day, in an air battle over the Hejin Triangle, "Ma Tuan O" lost his wingman, but he shot down a Japanese plane and damaged another: Chu Niu's eight-man air force suffered multiple casualties, while the 2nd and 3rd units of the Nozomiu team destroyed 8 Japanese fighter planes, completely defeating the Japanese air offensive. Even more fortunately, his downed wingman pilot successfully parachuted out and was picked up by the guerrillas below and successfully returned to the base.

He should be receiving psychological counseling now, right? "Ma Tuan 01" thought as he pressed the call button on the headset again.

"Ma Tuan 03, Ma Tuan 01, how's your 'rookie' doing? Need an emergency landing? Over."

"Ma Tuan 01, Ma Tuan 03 calling, Ma Tuan 04 is fine. There's a slight leak in his tank, but it's not serious. He should be able to make it to Hancheng, but getting to Liyang will be a bit difficult. Over." "Ma Tuan 01 understands, over."

The team leader skillfully released the call button and found a switch in the corner of his dashboard. He adjusted the switch for this device that was very inconsistent with the style of the watch shop.

A frequency. Along with a burst of alternating current sound, a girl's voice came

Came out.

"Ma Tuan 01, this is the breakfast shop, the signal is clear, please speak."

"Breakfast Shop, this is Ma Tuan 01. We've shot down two enemy aircraft with no casualties, but Ma Tuan 04's fuel tank is damaged. Please coordinate with ground crew to prepare. Over."

After clearing space for the subsequent railway bridge, construction of the Yumenkou suspension highway bridge proceeded smoothly, with two project teams competing for bids. Meanwhile, the Eighth Route Army was leisurely mobilizing supplies and making all necessary preparations. Both the Xinzhong and Qian Changgan teams were top-tier in the country. Regardless of who was assigned, the bridge would require steel, cement, cranes, and excavators, and workers would have to build it piece by piece, bringing the blueprints to life.

Naturally, as a major wartime project, ensuring a safe construction environment was paramount. What was important to the Eighth Route Army was a thorn in the side of the Japanese. Given the difficulty of keeping the construction site completely secret, the Japanese would undoubtedly send bombers to destroy the bridge in its cradle.

The arduous task of guarding against Japanese bombing and air raids fell not only on the newly born Eighth Route Army Air Force, but also on the shoulders of the increasingly thinning hair of the Central Industrial Commission of the Communist Party of China: the former had to compete with the Japanese for local air supremacy in the battlefield and ensure that no Japanese planes appeared at the construction site, while the latter needed to ensure that these planes could take off properly and intact.

As a delicate weapon, an aircraft not only needs to be loaded with ammunition and replenished with four fluids, three gases, and one piece of gas, but also requires regular repairs to damage from battle, engine maintenance, and calibration of guns, instruments, and actuators. Over time or if it suffers severe damage in combat, it requires a major overhaul.

This complex maintenance meant that historically, the North China Expeditionary Force could only permanently deploy fighter aircraft in Peking, Jiao'ao, and Yuncheng. Currently, Yuncheng Airport is paralyzed by frequent "sunny to cloudy, with mortar fire" incidents, preventing the 3rd Aircraft Division from permanently deploying in Shanxi Province.

If the Eighth Route Army wants to deploy fighter jets in the Hejin area for a long time, it will definitely need the support of such logistical units.

"If I have to build another airport, I don't want to cram it in a place like Fushe!"

Huang Jingzhai, head of the Central Industrial Commission, now stationed at the Eighth Office in Gaojing, shook his head at the suggestion of "ensuring safety." Although the Shaanxi-Gansu-Ningxia base area was newly established and had a strong mass base and familiarity, the loess plateau, with its steep mountains and deep valleys, was not a suitable location for an airport. The entire Fushi Airport had only a single runway, nestled beside the Yan River. Even with the hardened surface, taking off and landing aircraft was difficult, often hampered by wind direction.

"Why not build it in Guanzhong? There's so much flat land there."

After making harsh remarks to the Nationalist troops on the wall map, Comrade Huang Jingzhai began to think about where the aircraft maintenance center should be placed.

By 1940, the Eighth Route Army had two airfields capable of carrying out medium-term repairs on aircraft, in Fushe and Huinong, as well as several other airfields for simple maintenance. Following the February Incident, the Eighth Route Army effectively controlled Gaojing and much of the Guanzhong Plain. The flat and fertile land of the Qin dynasty opened its arms to the Eighth Route Army. However, among so many options, choosing a location with convenient transportation, open terrain, proximity to the front lines, and guaranteed safety was a real challenge.

After a period of headache, Comrade Huang Jingzhai weighed the pros and cons again and again and decided to follow the historical choice: at the Party Committee meeting, he chose Liyang County, located northeast of Haojing and on the Tongxi Railway, as the target of his proposal.

This is the northern edge of the Guanzhong Plain, which has already separated from the Shaanxi-Gansu Plateau further north. The terrain is open and the weather conditions are relatively stable. There are roads and railways passing through, and it is a place where border transport teams often pass through. It is only more than 100 kilometers away from the Hancheng front-line airport in a straight line, and transportation is convenient.

As for security, there were no more Kuomintang troops around Haojing in the south that could pose a threat; Tongchuan in the north was stuffed by Deng Yu and his newly formed 11th Brigade.

The intention was to "block the mountain pass and prevent the Communists from moving south." But I'm afraid Chiang himself

You know, this former Northwest Army general had already become a "Seventh Route and a Half": when he was in Yulin, he and the Eighth Route Army jointly opened mines and factories and built roads.

The first thing he did was to find the Eighth Route Army to jointly develop Yao County.

Cement complex.

"The nearest Nationalist troops are in Huayin to the west, nearly two hundred miles away! Even if Chiang Kai-shek is incredibly brave, I'd like to see if they have the guts to charge our Eighth Route Army!"

Huang Jingzhai was confident that this was indeed a good place to build aircraft. The Central Working Committee's team considered numerous factors and outlined numerous options. They had indeed considered almost everything. They hadn't anticipated that this place, in another time and space, would also be known as the "Aircraft City."

Chapter 345 Communist Party Project (III) Border Area Road Network Phase I

"Who is coming?"

"Who else could be driving a truck except our transport team? The guy at the front of the truck is 18' tall. You're so young, but your eyesight is clear, right?" "Ha! Master Yu! I've been waiting so long for you to finally show up!"

Captain Yu Weiguo of the 18th Transport Team had just jumped out of the car when the man in front of him put down his bowl, rushed over in two steps, grabbed his hand and shook it hard.

"Come on, Captain Yu, how about one?"

"Hey, Huo, Team Leader Yao, today you're not using the 'Workers, Peasants, and Soldiers', but the 'Pegasus' instead. Not easy, not easy. So I'm going to take advantage of your Fourth Construction Team."

Captain Yu said he wanted to take advantage of me, but I welcome you very much. You always bring good things and good news. If you come a few more times, the project will progress faster! "Leader Yao of the construction team let go of his hand and dragged the transport team leader to the kitchen truck. "Come on, come on, have you had lunch?"

"I've eaten, I've eaten! Hey, Team Leader Yao, let go! Finish your meal first!"

Although it is already September or October, the sun at noon is still quite hot.

The Fourth Construction Team of the Infrastructure Corps Railway Team is resting on the roadbed west of Suide. It's lunchtime, and the construction team's trailer has lowered the cooking table and stove. The engineers are holding large enamel pots with handles, eagerly waiting for the cabbage, oil residue, and egg fried rice to fall from the cook's spoon.

Cabbage comes from the vegetable car, while lard is a byproduct of cooking lard. Combined with rice and eggs from the logistics center, these two ingredients become one of the construction team's most popular dishes. The rich and moist texture of the lard is paired with the crisp cabbage and distinctly grained rice, and a touch of bright chili peppers, creating a savory, spicy, and oily dish.

At mealtime, the greedy new recruits usually line up first, filling their bowls and devouring them quickly to reward their tired stomachs. The experienced veterans, on the other hand, always fill half a bowl first and scrape the bottom of the pot at the end, hoping to get some of the crispy rice crust.

The enthusiastic Team Leader Yao wasn't so particular. He quickly finished his own bowl of fried rice, then grabbed a grapefruit slice from the kitchen cart that was packing up, broke it in half, and gave it to Team Leader Yu of the transport team. Then, Yu Weifu pulled out the electric speaker from his waist, turned it on, and shouted.

"Little monkeys! All members of the Fourth Construction Team, two columns, assemble!" "Prepare to unload the truck!"

“Ouch—!”

Yao Liang, the fourth construction team leader, had a remarkably loud voice, his words resembling the opening of a dam or the eruption of a flash flood. He carried the roughness and hardiness of a northern Shaanxi man, yet somehow felt familiar. Master Yu Weifu, on the other hand, had a more composed and steady style, like the loess mountains that seemed unchanged for millennia, evoking a sense of reliability.

This transport team and construction team have been cooperating for a long time and have a very good understanding of each other.

Some of the "Bulldogs" in the transport team have self-unloading buckets, which can unload the rails behind them by themselves, while some materials that are inconvenient to unload by themselves require the help of forklifts or manpower.

"Good riddance, go, be careful!"

Rows of rails, concrete sleepers and fasteners, and food and water supplies were unloaded from trucks, most of which were piled in the cargo area painted with white chalk, while the rest were piled onto flatbed cars on the railway.

Team leader Yao Liang held an electric horn and shouted at his drivers and engineers to drive a strange-looking "locomotive" along the railway tracks: this "locomotive" had a square cab, but no water-coal car, nor the large chimney and firebox of a steam locomotive. Instead, it looked like a truck chassis with the cargo box unloaded, dragging several gantry cranes supported by frames and steel structures.

This "train" was hooked onto a flatbed truck carrying cargo at the back, and a small winch wire crane was used to lift some components that were difficult to operate with a forklift or manpower onto the flatbed truck.

Beep! Someone blew a whistle and waved a small flag. A driver wearing aviation sunglasses and a wicker helmet climbed into the cab and started the train. The entire construction team carried tools such as tamping machines, steel chisels, hammers, and switch wrenches, and surrounded it, moving forward along the tracks.

That's right, this strange-looking "train" lacks a steam boiler—it's a portal-type track-laying construction vehicle modified from the "Dongfeng Tianjin" truck chassis from the Dili Canteen supplier system. It's specifically designed to address the shortage of locomotives and wagons during railway construction in border areas. The entire Fourth Construction Team is a mobile track-laying station that can be fully equipped with this 340-horsepower "diesel locomotive"!

all

"You've become so much better in the blink of an eye! I thought my Bedford and Bulldog were even better than the Big Ford, something truly remarkable!"

Half a pomelo flesh turned into dry meridian skin, a cigarette turned into a cigarette butt, and Yu Weifu finally opened up. The experienced driver sighed and pointed at the paving machine that was heading to the end of the track and placing concrete sleepers and 12.5 meter standard steel rails on the roadbed one by one.
