Proposed tractive effort/train speed relationships for the gas-turbine powered version of APT P (IM-PD-007)

1. Introduction 1.1 The tractive effort/train speed characteristics of the Gas-Turbine powered APT P have to be specified. P.D.4 discussed the subject of possible power levels and this note discusses the particular tractive effort requirements for starting on, and climbing, gradients. 1.2 Because the gas-turbine powered version of...
