New Locomotives on Southwest Pennsylvania Railroad

Last week, Southwest Pennsylvania Railroad accepted delivery of locomotive SWP 4006 & SWP 406.  This fuel-efficient pair features a GP40-2 mated to a GP38 core that was rebuilt into a slug unit. The resultant locomotive, which we call an “HD40-2”, is essentially a 3000 HP diesel-electric with 8 powered axles and two fuel tanks.  SWP 4006 was rebuilt and repainted, and SWP 406 was constructed from a former Penn Central GP38 as a tractive effort booster unit.  This work was completed by Metro East Industries, Inc. of St. Louis, Ill.
