Automatic Train

I am working on a game with a small automatic train, and want to know if there are any pages/previous posts/tutorials that would help.
All help will be greatly appreciated!

Does this mean you want to make a train that runs automatically?
if this so, there’s answer: How were the trains in Jailbreak done? [SOLVED]

It does help, however my train will have to be able to stop at stations.
Still a great help, thanks!

This is similar to a post I have seen before.

It looks very helpful, thanks!
