I'm converting a 2 rail Weaver RPO to 3 rail and found this lighting board inside. Am I right in assuming it's to provide constant voltage to the string of grain-o-wheat bulbs?

Probably, I've found a number of similar boards in 2-rail stuff when I'm upgrading them to PS/2.
Thank you, John. I'll save it for some later project where DC to low voltage whatever is required. Might be fun to experiment.

Had some time to fool around with this board. I connected it to a variable DC output and attached the string lighting of grain of wheat bulbs from the weaver car. As suspected it holds the lighting voltage to 6 VDC no matter if voltages rise above that.
I then applied AC and got the same results. So if you have these, John, they're a nice neat little constant 6 VDC supply with 3 outlet connections for convenient hookup.

They supply the lights and the Seuthe smoke unit power. The one you have appears to be the switching model for higher currents, many are just linear regulators and only good for a couple hundred milliamps maximum.
It does appear to be rather robust. Until you mentioned it, I never thought about using it to regulate a smoke unit. Hmmmm....I smell rubber burning.

I don't know the actual power capability of that board, but being a switcher, I suspect it'll probably do at least an amp at 6 volts.
....and one thing leads to the next. I pulled the shell off my old MTH GG1today in preparation for the upgrade. Inside lay a separate lighting board with basically all the same components attached...minus the switch.

I've gotten various design regulator boards out of a number of different upgrade projects. I gave a bunch of them away recently, I don't really end up with a use for them.
6V seems to be the standard. Williams brass used a 1.5a rectifier with 1A liner regulator to drive headlight, markers and seuthe smoke unit. Usually the marker connection has 75-300 ohm resistor in series to limit current for the LED markers. Pretty standard fare. I keep them for repairs. Some folks still run conventional. G
