I found an extensive report on this from 2007 as to the S.F. Bay Area (BART) commuter rapid transit system: http://www.bart.gov/docs/BARTenergyreport.pdf

Analysis was done on a per-car/mile basis. Per the chart on page 2-1, car usage averaged between 3.37 and 3.62 kWh per car-mile. Later charts in the report show propulsion accounting for 83% of the total electrical usage.
