I guess that you mean to ask if the numbers for the numberboards are in a
Numbers on number boards are generally put on for the train that the loco is
running for most railroads. I don't know what the UP did for numbered
trains but I suspect that the numberboards did have the train number there.
Most modelers put the loco number there as many trains ran that way. I'll
also note that adding numbers in there at the factory is a bit more
difficult than with lettering elsewhere on the loco and usually isn't done.

The UP was one of the few railroads which put train numbers on the
locomotive numberboards. Usually the lcomotive number went there (I
think Santa Fe was another that did it like the UP). However,
prototypically, you could put the locomotive number on the
numberboard, preceeded by an "X" - X4017, X4019, etc. That's how the
UP did it when the locomotive was hauling a non-numbered or
unscheduled train - an "Extra" - and still do, on 3985 and 8444.
Good point! Now, I have seen numberboards for Big Boys that were white
letters on a black background. Did they ever do black letters on a white
background? I have black decals - that's why I'm asking. ;-)
Frank, Bob is right - use decals. As to the colors - ALL Big Boys
(and all other UP steam) used white numbers on a black background.
Actually they are metal stencils painted black, over a translucent
glass lens. This makes it easy to change numbers when they change
