Vem har konstruerat alla olika rälsvikter. En del är förmodligen gamla svenska, då de stämmer med svenska måttenheter.
*14,32 kg/m = 10 skålpund/fot
*17,18 kg/m = 12 skålpund/fot
*24,34 kg/m = 17 skålpund per fot
*28,63 kg/m = 20 skålpund per fot.
UVHJ:s rälsmodeller är väl typiskt engelska 22,27 kg/m = 15 lb/ft, 24,79 kg/m = 50 lb/yard.
Jvm har väl en samling av olika rälsmodeller, vilka typer finns representerade där ?
