I’ve often thought about/wished I could put a turntable on my layout. That one looks like it worked out great for you and the location is ideal. Too bad you need access to the sump pump, otherwise you could have had more 27” long whiskers. The short whiskers will be perfect for handcars and speeders. Excellent that you could have two leads to it. Only drawback is that you don’t have much room left for scenery and structures.
You will also need about a dozen of these.
