The good folks at ExactRail send me an email at the beginning of each month, highlighting their monthly specials. I've been trying not to buy very many freight cars, as I think that I've actually got plenty, but this month featured a sale price ($29.99 USD) on their 50 foot Evans boxcars. These particular at this price apparently struck a nerve though, because I went ahead and ordered 3 of them for myself.
Telling myself that it would make sense for another CN car to appear on the GTW, I included this one in my order. The boxcar red or brown or whatever it is appears brighter in person than in the photo.
