Train randomly stops

[FyreDay]

I was testing to see if I could make a train in a test map but it randomly stops... I tried making my gate have no collisions and even moved it out of the way, but the train still stops.

I have attached my .vmf file

Thank you in advance, im guessing I did something stupid that messed it up, but I cant figure out what

I'll check what's wrong.
EDIT: I really don't know what's wrong.
