I would think of itl ike this; ther is a Track bricks with curves and straight pieces. The actual train is a vehicle. There is a station brick( It is a track pieces not the whole station, you would build the station your self.) that you can build on and auto-maticly <---spelling -.- slow the train down to know you are at the station if it is hard to notice this way you can stop if there is a problem like..,. " THE BIRDGE IS OUT!" Another cool feature for that would be the train takes a cool down time of 3 seconds to slow down. that concludes my theroy of "The Train mod."
