I have posted this in the General section as I think it could be useful for both DC and DCC systems. I'm going to describe how I've fitted internal lighting to one of the Pullman coaches that is in the GWR Western Pullman set R1077. This first post will describe, in text, what I did and then I'll post again with photos which will be held by moderators and so probably will not show until Monday. These coach bodies are held only by four clips, one in each corner. Undo by sliding a thin screwdriver and lever the body away from the chassis. Pull the roof off and then pull the white plastic shell out from inside the roof. This shell forms the seats, coach floor and partitions. I sprayed the shell with grey primer, painted the floor with black matt and then stippled a random red pattern over the black. Seats were painted medium blue, tables white. You have to look closely to see any of these colours! The gold coloured table lamps can be pulled out with small pliers before spraying and refitted later. The tops of the partitions fit snug to the roof so I cut shallow recesses to allow the LED strips to run the length of the coach, I also cut out the tops of the end sections [will be clear when you to see a photo]. I fitted two phospur bronze strips to one bogie [i used Slater's Ref:1220 which has enough in the pack to do 15 wagons]. The bogie has small strengthening gussets and I cut away a small piece of the gusset and epoxied two small offcuts of H section plastistrut either side of the gusset. This was to provide a flat bearing so I could glue the strips. Each strip was 49mm long and I soldered a short piece of 10/0.2 equipment wire to the middle of the strip, the strips were bent to what I think is called a compound curve! See a compound bow? A drilled a small hole through the bogie for the two wires but before fitting the strips/wires I temporarily placed the bogie on the chassis and drilled up through the bogie hole to mark the chassis. I then cut a curved slot in the chassis corresponding to how much I thought the bogie would swing going around my layout [no first degree curves]. I glued a 1.5A 50V bridge rectifier on the upper surface at the end of the chassis. A point to note; the shell and roof only fit one way, they cannot be rotated 180 degrees - check and double check you're cutting and gluing at the right end! After fitting the bogie I soldered the two wires to the AC terminals of the bridge, covering all bare wire with heat shrink. I didn't want to have the lights on all the time so I have fitted a small single pole slide switch under the chassis, I actually cut a slot in the shell floor [spoiling the exquisitely finished carpet] but now know if I pack the switch lower by only 2mm the terminals will not come through the shell floor. So you can guess I fitted the switch and connected to the positive bridge output and then ran a wire to go up to the roof and inserted a 10K resistor in line. Some may think that's a bit high but I don't like the lights too "in your face". I had to grind away some of the shell to make a route for the wires to & fro the bridge and switch. Wires are sandwiched between the top of the chassis and underside of the shell. Nearly finished... I've got some of those self adhesive LED strips which I think are great products, I've already fitted to several buildings on my layout. Mine are warm white 3528 and have inbuilt resistors for a 12V supply, the individual led's are at about 17mm centres and can be cut in groups of three. As I just said I added an extra resistor to dull them down. Unfortunately the coach roof has a [female] tube protruding down about midway along the coach that fits to a [male] tube fixed to the chassis to help keep everything aligned. This meant I couldn't run a single length of LED strip and had to rig up a bypass around the tube(s). After I had prepared the LED strip I soldered to the two wires coming out of the shell top, exposed the sticky back, fixed to the roof and assembled the coach. Now busy doing my remaining six coaches, only three came with the original set but a rake of three doesn't look right - not that I'm a rivet counter, far from it. Dinner time, will try and load some photos later.
