Mark,
Thanks for the info. I'll get around to that change, later. Doing some other engines, presently. That happens when one is not an expert on other railroads.
I should be able to use some solvaset to dissolve the numbers and then put on another clear coat.
As for the cab, space is always needed for curves on models, even with my 48" minimum radius, that is extremely sharp on a full size railroad. The enclosed cab detail came with the engine by the manufacturer and I'm comfortable with it.
