The Bombardier–Alstom HHP-8 (High Horse Power 8000) is a type of twin-cab electric locomotive manufactured by a consortium of Bombardier Transportation and Alstom for Amtrak and MARC. The locomotive's electrical drive technology is directly derived from the SNCF BB 36000 manufactured by Alstom. A small class size and reliability problems with correspondingly high per capita maintenance and replacement costs led Amtrak to retire all of its HHP-8s after only a decade in service. MARC initially made the decision to retire their HHP-8s, but later opted to refurbish their fleet from 2017 to 2018. |
