How can i get my Monorail to continuously move, non stop?

currently I've already designed a perfect monorail. it works fine. add some transparency to the wheels and i good to go. but that's not the problem, what IS the problem is this :

• as the title suggests i need it to move continuously . the wheels have some force acting upon it. the script i'm trying to design has to move forward. non-stop. no-matter what force is upon it. non-stop.

Before i end this question. i need just one thing. if you cant give me a script, according to the rules. then can you give me a wikia or wiki on how to do it? sometimes when i type i put something that might be incorrect so i need your help. what wiki can show me. and if there isn't a wiki. could you give me a place in roblox turtoil. other then giving it on here? so it can follow the rules? stypi,anything?
