working on a leopold

For my step-grandfather who had his head buried the whole time at Anzio.

Question I have is in the rail wheels. Were they primed with a rust inhibitive paint (a reddish brown or brownish red color) and just left that way or were they painted the same as the rest of the train car.

Would the wood decking have been painted or left in it’s natural state with a creosote type of waterproofing?

I have one reference and both that and the stuff online is pretty unclear.
Thanks

Take a look at this guy’s model, plus several others, they might help;
