Hello! This may be something someone may have already encountered. I have never used magnetic uncoupling ramps before. So, I bought a 2-pack. Placed them loosely on the track. Ran a Bachmann GP7 sound equipped loco over it and the loco grabbed the magnet and dragged it along. ?? I have never seen nor heard of this. What is the K.I.S.S.? If I glue the magnet down, will that slow the loco down when traveling over it? Or is there a better solution? The GP7 has the speaker in the fuel tank, right above the rails.

   I've had this old S scale gondola laying around for a while and am thinking about painting and lettering it.  It's a 40 foot gon with solid bottom and pretty high sides. It has some strange looking large side ribs and large end corrugations but pretty scale sized ladders, steps, and grab irons. It looks like a cast car, some kind of shiny metal,perhaps aluminium. Probably from the early days of S scale. Anyway does anyone have a suggestion for a paint job that might look somewhat like a real car? Any roads that ran high side 40 foot steel cars? ...DaveB

hello, I am trying to work out how to use an Arduino to sense when a building is occupied by a car, be it for loading or unloading. I have an Arduino and several infrared sensors (the kind with the receiver and emitter LEDs on one pcb) and have been looking for ideas on how to use them. I've found some ideas for parking sensors, but they use ultrasound sensors. the idea I have in mind is to use the IR sensors to detect a car and then light either a green LED (meaning the building is vacant) or a red LED (meaning the building is occupied).

I'm currently building a 14 stall roundhouse (Walthers kits), leaving the rear walls of 5 stalls open to the aisle allowing visitors to view the interior. What equipment would be present in a 1955 era roundhouse? I would think ladders and work benches but what else should I include?  Google searches have not gleaned much information. Any advise would be MUCH appreciated.
