I'm making a train that goes forward on a track when you press a button, then when it reaches its destination, have another button the will make it go back to where it came from. this train would carry passengers a to b and back. I don't want user controls and want to lock the buttons so player cant press them when their in transit. I have an idea how to do this but I'm not very good with trains since i haven't used them much in my maps. I've tried making one but i couldn't get it to "branch" right. I also had the other button set it backwards but its too slow and cant speed it up. Any help is much appreciated.
