While agonizing over the drying shed roof, I tried several methods of simulating corrugated metal roofing. There’s a method of casting the material in PVA using a styrene sheet as a mold.
On a 1/2″ grid. This works well, but I needed single pieces larger than I could reliably make. I also looked at using tinfoil, but that method is better suited for representing smaller pieces.
I tried some printed textures, but details like the corrugations were significantly affected while trying to get a good color. Unless I wanted to build a texture from scratch, that wasn’t going to work.
I noticed on the prototype there appeared to be a wood frame running along the roof edge. I figured I could use an earth-tone stick pastel along the edge of the styrene sheet to simulate this, and that worked well enough.
The top cap is a strip of #110 cardstock and the roof was very lightly weathered by dry brushing a minimal amount powdered black pastel in the direction of the corrugations, then removing most of that with a damp wipe.
I did have to add a non-prototype detail with the addition of ‘No Clearance’ signs on the right corner support.
On the prototype the tracks ran straight, but in model world that’s not the case. The clearance is a bit tight, so per prototype practice I put up warning signs.
What doesn’t travel on the NPP in gons and flats moves in boxcars, and there are several places around the layout for house car activity. I’ve wanted to add dock ramps for a while, because forklifts without a way to access the car are useless. The first thing to do was find out what dock ramps from the 40’s looked like.
That looks like a very printable detail part, but as far as I can tell, no one has yet done so in N-scale. I scaled the ramp and made a drawing.
The platform is 0.015 sheet styrene and the frame is 0.010 x 0.030 styrene strip. Paint is whatever appropriate colors were to hand.
The underside prior to final paint. The frame is beveled toward the end and the vertical stops are cut to 2 mm.
