Time for some interiors.
I had measured each coach up for interior fittings, giving me essential heights and widths. Being kit built to my usual standard, I measured each compartment to ensure the subsequent parts actually fitted. This also entails marking each component with its location within the coach, but there you are. My first attempt was fitting out the E6 guard's brake compartment. I hadn't thought through the windows properly, but spent some time scribing planking all over the shop.
Having taken stock of my sheet styrene, I decided 40 thou would do for the floors, except where I'd installed brass sheet at the ends, and 20 thou for the various sides.
I assume there would be some kind of bench in the luggage/brake compartment, so I'll conjure something up later.
Of course, once I started on the passenger compartments I hit upon a way of making the sides. Cut a bit of 20 thou to fit and mark off the windows from outside. There are still inner frames to fit to the bodies, so the slightly larger styrene window apertures won't hurt. The whole idea is to hide the mess of brassmongery inside the coach where hinges and shoddy soldering abounds. The usual method of drilling the corners and joining them up with a sharp blade, followed up with some careful carving, made each bespoke side wall.
One coach, more or less fitted out. Nothing is glued yet. I was going to scribe planking on the compartment walls, and the side walls, but some picture research leads me to think it would be wasted effort. It appears the interior walls were smooth, or at least appear so in the one photo I have. I shall paint them an off-white, to counter the dark blue of the seating and, probably, carpeted floors. The guard's compartment will probably be painted a buff or cream, with dark wood floor.
That's one coach done, three to go. I may be some time!
