They are all weathered with MIG products washes and Pan Pastels, except the BAR car which just got an India ink Alcohol wash and some artists oils (I scratched the paint. So I added a rust spot to cover it up.)
In the pictures the cars all look glossier than they appear to the eye. I need to work on my lighting a bit more to get the dusty look of the models to show up.
First up the Grand Trunk Tool Car.
Next is a P&LE Steel Side Rebuilt Boxcar based on the Tichy kit, with many upgrades including but not limited to doors and decals from Speedwitch media. I went heavy with the weathering on this car as it would be nearing the end of its life for my future Grand Trunk(NEL) layout time frame.
Third is a EJ&E car. This is a Branchline Car kit bash. It's based on an Article from the August 2013 issue of RMC. Decals are from Tichy.
Finally a BAR PS-1 using the Intermountain kit and Highball Graphics Decals.
