The Athearn ATH25568 is a top - notch N scale product. This set includes four 40 - foot 3 - bay ribbed hopper cars with a load from BNSF. The cars come with a removable load, adding to the fun and flexibility. They feature a ribbed side body, flat or peaked ends, and either roller bearing or Bettendorf trucks. The machined metal wheels and screw - mounted trucks ensure smooth operation. These cars have a scale profile brake wheel and can operate on Code 55 and 80 rail. The painted die - cast under frame and highly - detailed, injection - molded body are accurately painted and printed. They are weighted for great performance and come fully assembled and ready to run. With a minimum radius of 9 ¾”, they're suitable for many layouts. The coupler style is McHenry Scale Knuckle, and they're recommended for ages 14 and up.

Using your Athearn N scale hopper cars is a breeze. Since they're fully assembled and ready to run, you can place them right on your Code 55 or 80 rail track. The minimum radius for operation is 9 ¾”, so make sure your track layout meets this requirement. When you want to change things up, you can remove the load from the hopper cars. For maintenance, keep the cars clean. You can use a soft, dry cloth to wipe the body and wheels. Avoid using harsh chemicals as they may damage the paint or the plastic parts. If the trucks seem a bit stiff, you can give them a light lubrication with a suitable model - train lubricant. Remember, these cars are recommended for users aged 14 and up, so keep them out of reach of younger children to prevent any choking hazards from small parts.
