A care package arrived today, returning the old Heljan turntable bridge parts to rejoin the pit. It appears I have all the bits and pieces now to put Humpty Dumpty back together, including a robust and quiet gearhead motor. The extra bits were included in my purchase of the module base that the prior owner had assembled and wired, and which worked really well. You can see the original installation running at around 5:45.
My aim is to upgrade the appearance with some finer details, like a new bridge and an operator's shack, and get it built to where it operates at least as well as the original.
You'll recall that the original Hagerstown Roundhouse went to
@PiperguyUMD along with the original powered turntable. I still have the platform because it wouldn't fit into his car!

This is more or less how it will be configured here on the new layout, occupying the lower level on the B&O route. The higher WM route will pass behind the roundhouse on an embankment.
I'll keep you posted on the rebuild of the turntable as time permits.
