Making movers

Bear with me if this is the wrong place, or it has been requested before.

Is there anything that’s in GMOD (not Hammer) that lets us create movers?

Like, if i wanted a train, i could spawn a Razor Train model, use a tool to make it move, and set waypoints it travels between? Maybe set speed as well.

Also, so the game doesnt get choked up with models, make them disappear after a while.

I can think of a few uses:

Trains, Cars, Planes/Helicopters in skyboxes, maybe making certain areas look more realistic (like docks, they could have moving cranes, containers and such)
