Notes on Table
- Boiler Pressure is given in the SI unit of bar, where 1 bar = 105 N.m-2 = 6.894758×10-2 lb.in-2;
- For steam locomotives the Tractive Effort is calculated at 75% of boiler pressure and for diesels at 25% track adhesion, where 1 kN = 103 N = 4.448222×103 lb;
- The total operational weight of the locomotive is given, including the tender;
- The total length of the locomotive is given, including the tender;
