Wargames and Railroads: Calamity acquires additional rolling stock

Over the last couple of weeks I have managed to acquire a few more pieces for the Colorado & Northwestern Railroad that will be serving Calamity. This time I found a 4-6-0 Ten Wheeler, a type that the C&N didn't actually own but the price was just to good to pass up. I'll do some research and see if another one of the Colorado narrow gauge railroads used this type and letter it appropriately. I finally managed to acquire a combine car, its painted in burgundy so it will have a date with the paint shop for a nice coat of Pullman green. I also, accidentally, acquired another passenger/observation car also in burgundy so this one will be reserved for the railroad brass. The last purchase was a pair of flat cars. At this point I would like one or two more cattle cars and, of course, box cars. I have managed to acquire one at this point and would like at least 2-3 more and I need some short bottom dump ore cars. Taurus Products makes these but since they batch produce who knows when they will be available not that there is a pressing need for these until I actually build the On30 layout itself (separate from Calamity). I have the Taurus ore cars in HO scale so at the very least I have plans for them that I could scale up and work from. I need to dig through my railroad magazines and see if I can find the article on modifying On30 cars to ride lower to the ground.

Here are a few pictures (bad, I know, one of my lights is out and apparently I'm out of bulbs). I included a picture of the 4-4-0 American and the 2-6-0 Mogul just to give you an idea of the size of the locomotives. Now sizes varied a lot, there were big 4-4-0s and small 4-6-0s just depended on what a railroad needed and of course when they were built. Most of the locomotives made by Bachmann seem to be post 1900 so they aren't exactly right for my 1870 town of Calamity, but they are close enough, my players certainly aren't going to care.

4-6-0 Ten Wheeler - At the very least it needs to be re-lettered for a Colorado railroad.
Updated: Looks like I have a couple of options Rio Grande Southern and Denver & Rio Grande. I'm leaning towards the D&RGW for this one as it should be easy to find decals ready to go, although the RGS's scheme is a bit more interesting.
