I am having trouble completing this scenario. I have tried several times to place RS1 #5 in the correct location, but every time I move the turntable the engines cause a derailment. I have centered the engines as best I can but it doesn't seem to help.

Although I'm not familiar with that particular scenario, I have certainly seen turntables shake engines off their bridges. In some cases, pressing the 8 key to detach the camera from the engine has helped, but not always. As you noted, centering the engine on the TT is very important. How are you moving the TT: by clicking within its bed or by pressing G or Shift+G? Since T2015 came out, I've frequently seen turntables whip in one direction, stop rather abruptly, and then start turning in the opposite direction, sometimes resulting in bucking off the engine; have you experienced this?

It is a core game problem with the turntables. If you haven't already tried this try tapping it in tiny increments. I find this works sometimes....I repeat sometimes.

Clicking within it's bed

Reran it from the last saved point. A very light touch in increments, and voila I got it down. Thanks for the suggestions.
