I have added the little raised panels between the celestory windows. they are in unpainted wood, and show up on the black roof very clearly. they will mostly disapear once painted black.
I did this with some divergence from the plans, which seemed to show a single raised panel in the short curved ends, and along the kitchen end of the car, which has it's celestory windows filled in.
since I am making a generic car, and not the Alamosa, I'm doing it my own way. Also I think the plans may show the Alamosa in it's current state, I don't know for sure. It was built as a coach, converted to a parlor car, converted back into a coach by the Durango & Silverton, and then later rebuilt back into a parlor car.
In any case the drawings do not show a smoke jack, or give info on roof vent location for kerosene lamps. I will probably try to extrapolate some reasonable location for the lamp vents. I may wait on the smoke jack, as if I do an interior later, Placing the stove properly will determine the needed smoke jack location. Nothing is more frustrating than doing a passenger car interior and finding the smoke jack on the roof puts the stove in a place that makes no sense, and having to re do the roof.
