The bi - directional LED constant lighting ensures consistent headlight brightness. The 5 - pole motor with precision - machined flywheels and multi - link drive train guarantees trouble - free operation. All - wheel drive with precision gears provides smooth and quiet running, and all - wheel electrical pickup ensures reliable current flow. The heavy die - cast frame offers greater traction and more pulling power. It comes with McHenry® operating scale knuckle couplers and a DCC Ready 21 pin plug. The nickel - plated, blackened machined wheels with RP25 contours can operate on all popular brands of track. It's fully - assembled and ready - to - run out of the box, painted and printed realistically, and has a highly - detailed, injection - molded body. The minimum radius is 18 inches, and the recommended radius is 22 inches. Sound - equipped models have an onboard DCC decoder with SoundTraxx Ecomani sound. The sound units work in both DC and DCC. Full DCC functions are available in DCC mode, and all functions are NMRA compatible. It offers precision slow - speed control, allows programming of a multiple - unit lashup, and many functions can be changed via Configuration Value (CV) changes with a CV chart included in the box. The 2 - 8 - 0 wheel arrangement, with two leading wheels on one axle, eight powered and coupled driving wheels on four axles, and no trailing wheels, was a great heavy - freight design from 1866 to 1915, offering more tractive effort and a larger boiler.

Using your Athearn HO scale 2 - 8 - 0 locomotive is easy. Just take it out of the box, as it's fully assembled and ready to run. Connect it to your track, and it's good to go. If you're using the DCC and sound features, make sure your system is set up correctly. When operating, remember the minimum radius of 18 inches and try to use the recommended 22 - inch radius for better performance. For maintenance, keep the locomotive clean. You can use a soft, dry cloth to wipe the body. Periodically check the wheels and axles for any dirt or debris that might affect the smooth operation. If you need to adjust any functions via the Configuration Value (CV) changes, refer to the CV chart included in the box. Be careful when handling the locomotive to avoid damaging the separately applied wire - form details or other delicate parts. And when storing, keep it in a dry and cool place to prevent any damage to the paint or the internal components.
