For the 600-series coach conversions, like the New Haven, I need to modify the interior and remove the rooms and parlor chairs and replace them with walk-over coach benches.
Before I get to how I'm detailing that, it probably helps to get there first...
Disassembling the Walthers Parlor Car
The model is ingeniously designed, and, except for a few screws and the windows, everything snaps together. There's an inner plastic frame and roof and sides simply snap in. To get the roof off I used a plastic painter's palette knife to pry the sides outward to free it. You can see the notches at the top of the false side, with the slots underneath them. That's where the roof attaches. The round holes are for small alignment pins on the car sides.
Building the Interior
I drew a center line, then marked out the aisle for reference: 23-3/4" from the plan, or 12" on either side is fine. Precision isn't necessary here since it's not going to be very visible from through the windows.
The women's saloon is on one end of the car and is 6' long. This is on the same side of the car as the car side that required the window arrangement to be modified.
At the other end, it is split into two parts; the lavatory is on the same side of the car as the women's, and the lavatory is on the opposite. These are both 4'-91/2" long. These are very close to the size of the Branchline lavatories so I just used those.
They consist of two pieces, but the partition is designed to fit into the Branchline side. I removed this long tab to make a simple partition.
