Using these HO scale Kadee / Bettendorf 50 - ton trucks is easy. First, you can mount them with a #2 or 2 - 56 screw on your model. When handling them, be gentle as they have delicate parts. Keep them away from strong magnets because the wheels are non - magnetic. For maintenance, regularly check the axles to make sure they roll freely. You can clean the wheels gently with a soft cloth to keep them in good condition. Also, store them in a dry place to prevent rusting on the metal parts. This will help these trucks perform well and last a long time for your model railway setup.
