Malfunctioning Elevator

Hey everyone, I have a question:

How can I make an elevator that moves up and down as though it is malfunctioning?

Also for it to emit sparks when it stops at either the top or bottom before it cycles up again.

Do you mean shake rapidly up and down? Or like go to the top then back down to the bottom at a normal speed, only can’t be stopped?

have it play loud screeching noises

Well, randomly oscillate up and down, as though it is malfunctioning.

Screeching noises would be ideal.

Make several path_tracks, but don’t connect them in a line. Make path go forward, then back, then forward again, with the path entities (what were they called again?) at the points where the train reverses direction. Keep them all colinear though.
