Target car weight to NMRA RP-20.1 for every common car length in N, HO and O scale, in ounces and grams, and where to put the weight.
Every page here is computed rather than written, so the figures match the calculator that produced them exactly. Where a figure is a hobby rule of thumb rather than a published NMRA standard, the page says so. Every table is plain HTML you can quote.
