Pennsylvania Railroad class J1. Water cap. 124 scrapped, 6435 rumored to still extant but not confirmed. The PRR J1 was a class of 2-10-4 "Texas" type steam locomotives built between 1942 and 1944. The J1 had over 95,000 pounds-force (422.6 kN) of tractive effort, plus an additional 15,000 lbf (66.7 kN) if the booster engine was used.
The "10" is the ball diameter in millimeters. The "3000" is the force in kilograms force. The hardness may also be shown as XXX HB YYD 2. The XXX is the force to apply (in kgf) on a material of type YY (5 for aluminum alloys, 10 for copper alloys, 30 for steels). Thus a typical steel hardness could be written: 250 HB 30D 2. It could be a ...
