Brian Smith sent along this very sharp looking picture CN 4730, a GP38-2 built in 1973. Brian took the photo last Saturday at the yard in Huntsville, Ontario.
Not sure how this could be modeled, but maybe paint the long hood white, then a layer of chipping fluid, and paint over that with black acrylic. Then start removing most of the black until the effect in the photo is achieved. As for the primer coloured diagonal stripes...maybe paint stripes from a decal set and apply them. That's two maybes. Best of luck to anyone that tries them.
The concrete platform in the foreground looks to be just as worn as the paint on the locomotive.
Here at Sarnia's "C-yard", is this Pullman-Standard 4-bay plastic pellets hopper. It appears that the roof has become quite rusty, and the rust has been streaking down the side panels for some time. I wonder just how the 9 ribs got scratched that far up the sides.
Unfortunately, to the best of my knowledge, no plastic model of this type of PS covered hopper is available.
Back to the HO stuff, below is a CN boxcar owned by Jamie Barron, given a light weathering with slightly faded paint and a few rusty scratches. I thought that the roof rust turned out very well.
I added most of the exterior ribs to an 86 foot boxcar that I'm converting, with the intention of painting it as an SSW (Cotton Belt) auto parts car. This should match up well with two of the same type of boxcar that I've done in the past and decorated as Southern Pacific.
In the photo below the boxcar body has been painted with primer, and the wheels and trucks are painted with Krylon Camouflage Brown. That's my scratch-built (can you tell?) painting stand that I take outside when spraying with rattle can paints.
The boxcar is painted red and the grey decal striping is underway.
Applying the decal stripes is a pretty meticulous job. Microscale sells the striping and arrows as a set, but there are so many ribs and both horizontal and vertical posts at the doors that I've found that they simply cannot be laid on in one piece. It helps if I limit myself to doing just a little bit at a time and move on to something else. The ribs in the area between the doors will be added at the end. I should have more on this car done for next time.
