Thanks guys.
LOL hehehe yeah no more white walls.. >: )P
No I actually control these with a manual switch. There was a total of I think 14 lights (the are MTH 5v bulbs) and it would have taken 7 additional light circuits to have powered that many. Their light circuits are presetup to to run either LEDs or incandscent bulbs. The existing cab light, and # board light circuits were taken up. Ditch light circuits are powering the firebox lights. The rest are either for mars lights or LEDs,for marker or beacon. It would be nice to be able to automate them, but the switch works out ok for me. It's located at the front side just inside the firebox on the fireman's side. Since I have to flip the switch to turn on each passenger car anyway when it's night, it's just one more switch to flip. ; ) This is probably one of those areas that you may be able to get a DCC board with more circuits and be able to program their control. With DCS you can't get in and change the function of the light circuits, they are preprogramed for you and setup. It's always a trade-off, less ability/need to customize setup leads to easier setup and configuration. The more options and configurability, the more work it is to setup and get running.
Back in 1977 when I saw it, the engine actually did have lights. Now whether they had them originally or added them for the restoration I don't know. I know my USA Trains BB has lights built in and they are intended to model real ones from the way they are made. So at least some steamers had them I think. This is an actual photo taken where I saw it Beaumont, Texas.
