So here is my second RailPro LM-3S install - an old-school Atlas U-boat. I heavily kit-bashed it a number of years ago using an Atlas U33C as a starting point and grafted an Atlas U23B rear radiator section for the U30C conversion. I also swapped out the stock Adirondack side-frames with correct General Steel Casting (GSC) frames. Numerous other super-detail parts were added and/or fabricated and then the whole thing was airbrushed SP scarlet and grey and then weathered to match the prototype.
The 1st photo shows the stock unit I started with.
The 2nd photo shows the mechanism completely disassembled so that I could properly clean and lube everything as well as solder the pick-up wires to the truck side-frames. You will also note in this photo that the two weights were milled down to give me the room needed for the LM-3S module and iPhone speaker. Well, only one was actually milled - the other was cut with a hack-saw.
The 3rd photo shows the finished install.
I left all of the extraneous wires so that I can eventually add headlights. I'm still looking for a source of SMD's that are of the proper color for 1970's vintage diesels. More of a sunny-white and/or golden white. Something with a hint of yellow and definitely no blue tone. I want SMDs large enough to be glued to the inside of the shell and still straddle both plastic "light tubes". Perhaps someone here can point me in the right directions here?
These older Atlas units run great! Nice and smooth and low amp draw.
I have a U33C yet to do as well as an AT&SF C30-7 that is still in the super-detailing phase.
Hope this inspires someone else!
