PlayStation Class 52 Derailed On Turntable Wsr

Tried doing the Diesel Gala scenario on WSR with the Class 52 Western, and despite parking the train on the turntable, the train derailed as I was operating the turntable. Not sure what I did wrong to cause it, but noticed the locomotive itself was shaking about a bit whilst the turntable was in motion.

Any tips to avoid the derailment?

 

Done this on TSW2020 theirs some markers, bottom right, how far on turntable. How that helps.

 

I remember it being a rough rotation on TSW2020 but i tried to bang in the middle of the turntable for better balance as i thought the weight and physics of it all were recreated in game.
