Details
Properly weighted cars are the quiet difference between a train that tracks and one that stringlines, uncouples, or picks a turnout. This free one-page reference puts the NMRA RP-20.1 recommendation for HO at your bench: find your car's body length, read across to its target weight in ounces and grams, and weight to match.
The lookup table spans the whole HO fleet — from a short four-wheel ore car up through an 89-foot auto-rack — in half-inch steps, so there's a row for nearly everything you run. It also covers where to add weight (low and centered, over the trucks) and the engineer's caveat that consistent weight and free-rolling trucks matter as much as hitting the exact number.
Print it, tape it inside a cabinet door, and stop guessing. Need a length that isn't on the card? The RailForge Scale Converter computes any car's target weight for you.
Make it real. Make it RailForge.
