Does anyone know what voltages are used for the lamps on the USA Big Boy? I am particularly interested in the headlight, Class lights and number boards, cab light and the ground lights under the cab.

Bill-
I'm not sure on the direct answer short of saying to call USA Trains and ask. Do you have a volt meter? Just check the two leads. I'd assume the light bulb would have to be able to handle full track power somewhere in the range of 18-24 volts.
I remove all of USA Trains wiring/electronics with my decoders. I prefer the LED route.

Look for a rectifier in the circuit before assuming full track power.
Often to have near full brightness at slower speeds the bulbs/lights are often 5-6 volts.
Using a 5volt rectifier your lights are controlled through fast speeds and the bulb/light is safe.

The bulbs in the USA Hudson are definitely not track power!!
I do not remember the exact voltage, but I do remember installing a regulator and I believe it was either the 5 or 6 volt unit.
