COMPARISON BETWEEN FUEL EFFICIENCY OF RAILWAY DIESEL AND ELECTRIC TRACTION UNITS
This paper shows that efficiency chains for railway diesel and electric traction units can be combined with unit costs of fuel to give a valid comparison between diesel and electric traction options on a given railway service. The data have been derived from existing types of traction and rolling stock on British Railways. It is shown by taking all relevant factors into consideration that electric traction has higher thermal efficiency than diesel traction. An important feature of the electric traction chain is that the input energy can be obtained from any source including nuclear heat and mechanical energy to drive generators directly as in hydro or tidal energy schemes. Where oil is used in electricity power station furnaces the oil is a lower grade and therefore cheaper than that required for heat engines.
