S Scale model train layout with operational NJ International operating railroad signals with a S Helper 2-8-0 B&O steam engine with the International crossing gate warning.
For those who know of the NJ International products, I have these RR signals operation with out the servo destroying the thin rod inside the gate. No way, was I going to drill a hole into the counter weight of the arm. Not the way these were presented in the instructions when the rod inside the signal was not a very thin weak rod.
