For the decals I bought two sets (the minimum per order) from Greg Komar. I bought PRR set #341 "Pennsylvania - Cabin Car Classes Nd, N6A, N6B, N5, N5A, N5B, N5C. 1926-1955 Lettering Scheme, White Lettering. No Herald". I got fantastic service from Greg, and I highly recommend his decals. I applied the decals to the model using a mixture of 50/50 distilled water and Walters Solvaset. The decals are very delicate and must be handled with extreme care. However, the big benefit of him requiring the purchase of two sets minimum for S-scale is that you always have a back-up! After the decals were applied and had dried for a few days, I gave the whole car a spray of Testors' Dull Coat to protect the paint and the decals.
After letting it all dry for a few days, I installed the couplers and the wheels. I put some weathering chalks on the side frames of the trucks. The couplers required a bit of trimming along the body parts to make them fit.
I also put a conductor in the car to liven it up a bit.
I placed the roof on the model and put the whole thing on a digital scale to weigh the model. The car weighs 4.9oz (138g) which is about right for this 6-inch model. Some weight will be added later on when I install the electronics to light the interior and the marker lights (all to be done at some future date).
The final step now that everything is done, is to install the window glass. I am using some very thin clear plastic I bought from Clover House years ago. It has a thin film strip on either side, which prevent finger prints from getting on the plastic while you're handling it. I cut and trimmed the pieces to fit the window openings and then glued them in place using Formula 560 "Canopy Glue". This photo shows two pieces being glued to the side of the roof.
Early on in the construction I had installed the air hoses, which needed to be removed to be able to install the brass end walls. I drilled a hole in the plastic end of the end wall and superglued the air hoses. I decided on the P-B-L ones (part no. PBL-555) because they are made out of actual rubber, just like in the real world. This close-up photo shows one of them installed.
