P-7 is an EMD E9-B power (heater) car. It has a generator which provides steam to heat passenger cars. It was built for Union Pacific as E9B #970B (builder #20510) in October 1955. It later became Amtrak #468 (E9B), then Amtrak #1919 (heater car). It later became Alaska Railroad P&. Finally, Union Pacific reacquired and rebuilt it as E9B with a 2000-hp, 645 engine. This picture was taken in Anchorage yard stored on the old main next to the old CEA power plant. This engine only had steam boilers in it - no prime mover for tractive effort.  |
