This Athearn ATH25569 set offers a 4-pack of N scale 40-foot 3-bay ribbed hoppers with loads for the BNSF. It features a removable load, ribbed side body, and flat or peaked ends. The hoppers come with roller bearing or Bettendorf trucks, machined metal wheels, and screw-mounted trucks. They operate on Code 55 and 80 rail, have a painted die-cast under frame, and a highly-detailed, injection molded body. The models are accurately painted and printed, weighted for great performance, and fully-assembled and ready to run. The minimum radius is 9 ¾ inches, and it uses McHenry Scale Knuckle couplers. Recommended for ages 14 and up, no assembly is required.

Using your Athearn hopper set is easy. Just place the fully - assembled hoppers on your Code 55 or 80 rail track with a minimum radius of 9 ¾ inches, and they're ready to run. The couplers are McHenry Scale Knuckle, so connecting them to other cars is a breeze. When you want to change the load, simply remove it as it's designed to be removable. For the best performance, make sure the track is clean. If the trucks or wheels get dirty over time, you can gently clean them with a soft, dry cloth. Keep the set away from small children as it's recommended for ages 14 and up. Store the hoppers in a dry place to prevent any damage to the painted and printed details.
