Marx #147815 Rock Island Boxcar. Here is a Marx Freight Car from Steve's Train City in Minnesota. The #147815 Rock Island Boxcar is a Deluxe freight car, with opening doors, made in 1952 to 1959. It has 8 wheels with plastic automatic tilt couplers and Type F trucks.
this is a very nice piece of rolling stock, but it did have one broken coupler on it. I have since found some replacement couplers so it will be good as new soon!
