Get your hands on this pair of HO scale trucks, Part # 380 - 551. These Kadee/Arch Bar Trucks are crafted from metal, fully sprung, equalized, and self - centering. They mount easily with a #2 or 2 - 56 screw. The Arch Bar Truck is a classic design from around the turn of the century and served for over seventy years in some cases. It was used until the 1920s and was banned from interchange after Dec. 31, 1939, though non - common carrier railroads like logging lines could still use them. For example, the Northern Pacific used truss rod frame maintenance cars with these trucks well into the 1970s. Truck features include Code 110 (0.110 wide) 33' ribbed back'standard' wheels, accurate markings, self - centering, true - to - prototype details, non - magnetic metal wheels, highly flexible sprung trucks, metal side frames and fully sprung bolster, smooth - tracking free - rolling contoured insulated axles, and RP - 25 free - rolling wheels.

Using these HO scale trucks is easy. First, use a #2 or 2 - 56 screw to mount them properly. When setting them up on your model railroad, make sure they are placed correctly to ensure smooth movement. As for maintenance, keep them clean. You can use a soft brush to remove any dust or debris. Avoid using harsh chemicals as they might damage the metal parts. Store them in a dry place to prevent rusting. If you notice any issues with the wheels or the centering, check for any loose parts. Just give them a gentle inspection from time to time to keep them in top shape.
