Hi
I have made a compatible version for the turntable. Myself and Chris Pearson have developed this. I have made a studio file and a sketchy PDF. Perhaps someone here would be interested in building it. The file, PDF, render and a video can be found on my bricksafe. I have also made a studio file for the L motor train. I think I have added all the mods that @doug72has done. If there is anything I am missing I can add it and then make some instructions, I am still learning how, so there are quite bad, but you get the idea. The turntable instructions are untested yet. The turntable is yet to go to a show, but during ~4 hr testing no issues. Although running it over the last few weeks I have found that the trip arms on some days want to be set up one way, then on other days want to be set up differently.
