Hi Phil! I took the 115 completely apart, cleaned everywhere, submerged rusty sections in Evap-o-Rust, replaced the pear lights and interior light, used penetrating oil and elbow grease to get rid of “B&O RR” overpaint, tested the original wiring, and put it all back together (not easy). I am waiting for the ivory and red paints, and aftermarket skylight, to arrive. I decided not to repaint, but to touch up formerly rusty bare metal to preserve the patina of age. I will post photos when done.
As far as wiring is concerned, it is fairly simple. On the underside of the base the stop switch wire is soldered to the 3 post. The power wire is soldered to the 1 post. The 2 post is a ground. If you want to illuminate the station without the stop function simply run the transformer U post wire to the 2 binding post and A or B post wires to the 1 binding post.
kind regards,
Pete
