"Hey, let's just do it." Zhou Youfu doesn't care.

"At this moment, the sky has not yet arrived, you can't see it, brother." Chu Tingchang poured a glass of wine for Lao Zhou, for the time being, he can only be so perfunctory, if he can really pinch it, why should he be in such a hurry?

The attacking troops stopped temporarily, and Chu Tingchang saw that it was getting dark, and he should avoid entering street battles without intelligence support for now. He didn't know how many enemies would be transported by rail in one night, and he didn't know when 419 would appear again, and he didn't know either.

The next day, the 5th Army launched a powerful offensive against the Japanese in the rest of the area, but the Japanese still relied on Chiang Mai to hold on and had no intention of counterattacking. In the two days of the offensive, the 5th Army lost 50 tanks, but fortunately, most of the losses were caused by *, and the vehicles could be recovered and simply repaired to restore combat effectiveness. However, the trend of trade-offs is becoming more and more obvious.

Xu Chong also didn't have reliable enough information to pry the situation in. Xu Chong is a master of field camouflage and an excellent scout, but he is not enough to infiltrate the city to reconnoitre, which is his limitation. When 419 left, the two people left behind, Xu Chong and Ma Qiangdu, had overlapping abilities and could not speak Japanese.

Lin Xiuxuan and Qin Xiaosu sat on the slow train, anxiously waiting to reach their destination - Chiang Mai.

In 36 hours, the train stopped and stopped, moving about 270 kilometers, and a third of the road nerds were still from their destination. Lin can feel from the continuous action of meeting and letting the car move that the capacity of this single-track railway has reached the extreme. The daytime train, which was dealing with Allied air raids, could not leave at 4 p.m. and stopped at the station overnight, and the military trains on other covert distribution lines would sneak out to the northern zone.

Even in the daytime, the Japanese would use the railroad with stitches, and the train could only stand on the sidelines, and its role was to deceive the Allied air forces. But the hundreds of soldiers of the 49th Brigade on the car are not the troops urgently needed at the front line.

The train stopped at the side fork of the station again, not far from the main line, Lin Xiuxuan could see the Japanese military trains whistling by from a distance, about every 40 minutes, such a transportation density, I am afraid that Chu Tingchang will soon be overwhelmed.

Although it was only a single-track railway, the efficiency of the railway had been exploited to the extreme, and the trains carrying heavy weapons and the trains returning wounded soldiers could move freely and freely on the same railway line, plus the temporary stops and refurbishments caused by Allied air raids. To some extent, the aggressive efficiency of the Japanese must be admired.

In the past two days, Lin Xiuxuan has observed that the Japanese railway troops are responsible for signaling and knocking down the work, and except for simple tasks such as adding coal and water, there are not a few locals on the platform. It is expected that the control signals and dispatches in the duty room will inevitably be Japanese.

It seems that the Japanese have studied the Thai railways very deeply. This kind of transportation efficiency is not something that can be achieved by extensive control, they should use a centralized signal scheduling system. On the surface, the siding signal and the artificial trigger are still used, but the control must be reliable, otherwise the single-track railway will be out of order. In the days before computers, this was the most advanced railway control system.

Along the way, he also observed many bomb craters on the side of the roadbed, saw Japanese sappers dismantling the fuses of unexploded bombs nearby, and saw downed Allied planes in the wilderness; See the Japanese railroad troops and the spare railroad tracks hidden in the villages along the way, ready to touch the bombed roadbed and rebuild the railroad. He also saw that the Japanese dragged the captured American and British pilots out of the streets, and the Japanese military police deliberately indulged the locals to beat these prisoners of war until they were beaten to the head and bleed.

Lin has not yet established communication with Chu Tingchang, but he can guess that Chu Tingchang's current greatest fear must be this railway line, which can be seen from the daytime bombing of the US military at any cost. But daytime bombardment is clearly not enough. Because the efficiency of the Japanese railway troops was extremely high. Even in the middle of the night when the lights are controlled, Lin can judge how busy the railway is by the vibration of the trains on the platform, and it is conceivable that a large amount of support is being sent to the north.

Such a complex transportation dispatch must be based on reliable telegraph signals. It is unlikely that these signals were transmitted by radio, as the radios would expose the trains, which would have been calculated by the Allies. So it must be through a communication cable near the railroad tracks.

He suddenly came up with the idea that as long as he moved some hands and feet on the cable and let the two trains collide, he could minimize the efficiency of destroying the enemy's transportation. It's not so much the direct damage caused by the crash of the two trains, but the time wasted by the Japanese needing to check the entire line to eliminate hidden dangers. If the problem could not be found, the Japanese had to reduce the number and speed of the train by at least half, that is, the capacity by three-quarters, which was the greatest support for Deputy Captain Chu. Far more powerful than hundreds of bombers.

Of course, it takes a considerable level of professionalism to do this, but fortunately, Qin Xiaosu is here. He told Qin Xiaosu his thoughts, and Lin felt that before 419 arrived at the designated position, the group approached the war zone too early, and its role was limited, so it was better to stir up the enemy's railway first. Qin Xiaosu felt that it was feasible, but the only problem was that the cable was buried deep underground, covered with several tons of gravel, which required large machinery to excavate.

On the third day, the train stopped and stopped during the day and slowly headed north, and in the afternoon it reached the platform, 50 kilometers from its destination.

The ferocious Japanese gendarmes barged in and read a notice from the gendarmerie in broken Thai and Chinese, limiting everyone on the train to get off the train within five minutes because the train was requisitioned.

Where did the passengers dare to delay, hurry to get off the bus with their luggage. Within five minutes, the Japanese soldiers with white hoops and wooden sticks rushed into the car and beat anyone they saw.

Lin Xiuxuan and Qin Xiaosu got off the car with broken suitcases, and they hurriedly left the platform amid the shouting of the Japanese. When Lin Xiuxuan passed by the duty room, the Japanese inside were sweating and busy preparing for centralized transportation at night, and he used the camera hidden in the box to shoot the scheduling control chart of the pipe section hanging on the wall.

Closed sections and configured signal devices are depicted on them. Of course, there is no need to shoot it, Qin Xiaosu glanced at it as he passed by, and roughly understood how they operated. The Japanese squeezed the railway out of oil, creating a potential threat of overcrowding and redundancy. Now all they need to do is play a few tricks on the signaling system, and it's hard to get to the source of the problem.

The two of them followed the sighing refugee all the way to the nearby woods, and just sat and waited for it to get dark.

Lin Xiuxuan carefully observed the garrison of the Japanese army along the railway. The Japanese had sentry posts every 2 kilometers, lookout posts on the hills, and cavalry patrolling along the way, and a wave of cavalry passing by about every 15 minutes.

The refugees hiding in the woods, each nibbling on their own dry food, began to chat, and everyone looked forward to going to the north as soon as possible to find their relatives Chu Tingchang's team.

"Have you heard, Pavilion Chief Chu's team has begun to recruit soldiers. Now we overseas Chinese are also accepted. ”

"I plan to let my two sons join his army, you two descendants, so young, do you also want to join Commander Chu's old man's house?"

An old man suddenly asked Lin Xiuxuan and Qin Xiaosu.

"Yes, we're going to his old man's house." Lin replied.

"If it weren't for my old bones, which would be useless, I would also go to the army and be a man...... Ahem, ahem. ”

"Old man, what's your bulging baggage?" Lin found that the old man had a lot of tools for plowing the ground.

"I worked as a gardener in Bangkok, and now the army is in chaos, and the craft is useless, but I am reluctant to throw these things away, so I take them on the road."

"Sell me these."

"Since you are going to defect to Commander Chu, I will give it to you. I said it would be able to be buried*. ”

"How's that going to work?"

Of course, Lin Xiuxuan couldn't ask for someone else's money for nothing, he left the money and bought a few small shovels for gardeners.

Common sense was that the wired telegraph cables used by the railroad were buried deep and covered with rubble, which was not so easy to dig up, but Lin knew he didn't have to make a big deal about it.

I saw that the sky was getting darker. The two of them took their things and left the group of ordinary people. The rest of the intelligence group that Lin pretended to recognize, who came in batches, have now been separated. Of course, it was agreed to meet at a designated place near Chiang Mai, so at this time, it is just time to do some small work first.

Taking advantage of the darkness of the night, the two quickly approached the railway, and could see the Japanese cavalry passing by with flashlights in the distance, patrolling back and forth in each section of the five-kilometer area, and there were also rolling cars that appeared from time to time to prevent someone from sabotaging the railway. The watchtowers built by the Japanese along the railroad were no longer a threat because they did not dare to use searchlights (for fear of being spotted by American bombers).

A train loaded with heavy artillery rumbled past, and the Japanese rushed to ship tonight in earnest. The two ran along the railroad for a while, and found a huge crater near the roadbed in front of them, which was a crater left by the Allied bombing during the daytime, and the Japanese 5th Special Railway Unit simply filled part of the crater, tamped the roadbed and resurfaced the tracks, but did not have time to fill the entire crater with gravel. So the roadbed is still missing, and this crater gives Lin Xiuxuan the opportunity to approach the signal cable from the side.

The two got into the crater. Qin Xiaosu used a magnetic signal probe to easily detect the position of the cable. The two men immediately dug and, every ten minutes, left the crater and hid for a while, waiting for the cavalry or the rolling carts to pass, and then returning to continue digging.

In the middle of the night, the cable was finally dug up. Qin Xiaosu cut the glue fart and connected a piece of wire, he didn't roll the wire with him, and he couldn't lead the signal cable to a distance to control, so he squatted in the crater and sent his own Morse code signal to the Japanese at both ends.

Before the Japanese cavalry arrived again, he had sent an erroneous signal, which gave the rear station instructions to drive and the military vehicles that had been stopping at the station should stay for another 40 minutes to avoid the returning train. Of course, Qin Xiaosu didn't know that the returning train was full of wounded soldiers, so he didn't violate the Geneva Convention.

The station waits for the signal to start in advance, and the signal light informs the station line that the train on the coaling platform will start in ten minutes. The train stoker wields a shovel and struggles to shovel coal, increasing the pressure.

On the steam-filled platform, a loud Japanese military song sounded. The train starts slowly, and the wrench in front separates the three-pronged line. The train took to the road with 1,200 Japanese troops and ammunition urgently needed at the front.
