I don't think it's a great stretch to consider that diesel-electric locos might run in electric only modeJFTR, the term "diesel-electric" does not mean dual-mode. It refers to diesel locomotives whose diesel engines power electric generators that in turn power traction motors. That is about 100 percent of revenue US diesel power, which does happen to include dual-mode locos (P32AC-DM, DM30AC and ALP-45DP). There are two other types, which are diesel-mechanical and diesel-hydraulic, not in use here since Southern Pacific retired their Krauss-Maffei diesel-hydraulics. |
