I do like the MTH "white" (actually sort of yellow for an incandescent 32volt bulb) class lights on their steam locomotive models.
I thought the same. I have those installed on one of my MTH engines. I tried to buy more to convert other engines and they were not available. In trying to buy extras, the shop owner referred to them as yellow, whereas I though of them as "a yellow glow white".
So the question for me is, why is it so hard to get a white class lamp? Santa Fe used white for just about all freight movements.
I like the fact you can turn the class lamps off with MTH engines. I think that 3rd rail would benefit from being able to use the "lamp on and off function" of TMCC to do more than turn the back up light on and off, perhaps it should be used to turn off the cab light, class light, or both like MTH does.
Yes, we need better lighting control. I'm still in the process of experimenting with my engines although it is on the back burner while working on my layout. I think you can do something better with RS4. I can pass on the headlight on/off and better use that function for the class lights or cab lights of both.
Thanks for bringing this up Rob, I was thinking of doing the same with regard to 3rd Rail engines on the 3RS board.
BTW, I'm talking steam.
