Good advice from train hobby friends is good news. In a few more days, I'll receive the PWM devices (shipped from China) for DC voltage and speed control of my three trolley lines, with DC power provided to them by a PC laptop power supply; those ideas were previously offered by contributors to this thread on the OGR FORUM. As of today, the trolley tracks are installed on the upper level, the lighted lock-ons are in place, and track power feeder wires are dressed up from the lock-ons back to the control panel. The remaining "missing links" are the PWMs -- which I intend to mount in a project box.
I did a brief, temporary test of the tracks with a HO power pack, and the trolleys worked OK. An encouraging result!
With thanks to all ...
