Train problem

Soooo i was in my world and i decided to experiment with trains to transport items however it isnt working but anyways a bigger problem is it keep losing its station and when i interact with the station it just says build a train despite there being a train, i used the original station and still the same thing , i eventually thought that it was too much a hassle and buried it in the ground. When i built another train it was the same problem but now it can actually detect when its near a train station and stops but i cant dissassemble because theres no option to and js something to build a train. Ive been troubleshooting but havent found a solution yet
