I’ve been interested in doing a railroad simulation. While I have managed to figure out all the other aspects of the sim I have yet to develop some kind of system to run a set of train wheels on tracks to guide the actual train.
It has become apparent that the concepts explained on the forum are really for a very simplistic track (helpful nonetheless,) but in my case I have a full working railroad with switching of track and other complicated situations where IPO will not work.
One concept that has gained my interest is with some kind of intelligent pathway device (which means I can have my train effected by physics also.) Attach empties to the the wheels and guide them with an actuator… Problem with that is when I have my train exit from a turn into a straight away it doesn’t go straight, but veer off erratically and shoot out into space. So my question is how do I make it compensate for it by steering it back on track?
I’m hoping I explained this thoroughly enough to receive some help…
