I bought 2 of the new 50' boxcars last weekend. They are very nice cars, but I have one question. Why are the roof walk and brake wheel not painted? The 40' boxcars have these details painted and I expected the 50' cars to be the same. It's easy enough to fix with a little paint, but I'm surprised it wasn't done at the factory. In any event, I really like the metal wheels, body mounted couplers and sliding doors, and I'll buy more of these cars.
