Hi Tom,
It's definitely on my "to do" list. I am still intrigued by the fact that access to the turntable tracks looks impossible unless you've hinged your entire turntable and pit, allowing it to swing down so that human help can come up in the middle to get to the tracks for assisting with derails, etc. Is that how you do it? I'm curious because that is how I did my own large turntable some years back.
