TRRR,
Here's a suggestion for doing the windows. Although you may consider it crude, I think it is satisfactory for placement on a model railroad and to expedite completion. For the window glazing on my diner models, I cut one large piece of acetate which covered all the window openings on each long wall. I then glued it to the inside of the wall. I think this looks fine when viewed from the outside. You can then apply framing (of basswood or styrene) on the inside to define the window frames on the interior and cover the inner edges of the glazing if you think it's necessary. It seems to me you could then apply the material to tint the upper part of the individual windows. These 1:48 scale diner models are really quite small. In my experience, sometimes compromises must be made, and it may not always be possible to achieve perfect modeling of the prototype. Perhaps that thinking is why I'm not even a contest entrant...
