Thank you Dennis.
LPTC, actually the bridge doesn’t span a door. It was a purpose built gap in the shelves along the wall so that I could use a bridge. A bridge was a mandatory feature for me, and it is set up as the centerpiece of the entire affair.
The set is the MTH Premier Tri-Rail set (loco sold separately), which I purchased from Ready to Roll Trains in Miami. You can see some other clips of it on my YouTube channel.
