Road turntable + Terence turntable help

I recently got Thomas and Terence Deluxe Set and one of turntable where terence get wood from. It turns when he goes out but it doesnt turn back. I had look all gear and everything, i dont see any broken or stuck gears. I moved all gears and all moves fine. No idea what stopping it turning it back. Any clue how to fix it.

Road turntable doesnt turn that well. Vehicle goes in only turn little bit then it stuck. It quiet tight to turn by hand. Any ideas how to make it move smooth?

Im not sure if this is on right thread.
