What is the meaning of beef jerky on the railway track?

Because there are toilets on the train, and the toilets are directly connected to the rails. Therefore, after the people on the train defecate, the excrement will stay on the track of the railway track, and then it will become very dry after being exposed to the wind, rain and sun. Many people think this is beef jerky and pick it up.

This is based on a video on Tik Tok, so it is often used to "pick up beef jerky on the rails and tease people with short knowledge", but this is just a joke video, don't take it seriously.

Slab track:

Made of thin iron sheets nailed to wooden railings. However, the bearing capacity of this kind of track is very low, so although the construction cost is very low, it is not cost-effective in the long run.

Rails used in railways must bear great pressure, so high-quality steel must be used. The requirements of railway rails for steel are higher than those for other purposes. The same small flaw, the steel bar used in the building, may not be a problem; However, the appearance of railway rails will lead to rail fracture and train derailment at any time.
