What are the classic jokes in the railway industry?

Buddy A and buddy B are both railway workers. A belongs to the locomotive depot and b belongs to the locomotive depot. One day, after work, they met for a drink in the hotel in front of the station. As a result, they both drank too much. On the way home, buddy A said to buddy B: I didn't think the handrail was so low before I sent you home with a drink. Brother B said to A: Yes, I don't think so either. Why is this staircase so flat? And there are too many steps in the stairs, I can't even walk to my floor! I heard a man with a manuscript shout "Don't die, the train is coming", and then I kicked the two brothers aside. At this time, a train flashed by, and the two brothers were immediately awakened by this shout. Take a closer look at the two brothers who just walked on the railway line. If it weren't for the rescue of the road maintenance workers in the works section just now, they would have died! Both of them could not help breaking out in a cold sweat. Since then, both brothers have fallen into the same problem, and they have to look back when going up the stairs, otherwise they always feel that there is a train coming! (original works)
