Amtrak HHP-8 with Northeast Regional Train Crossing Susquehanna
An Amtrak Northeast Regional train crosses the Susquehanna River
bridge connecting Havre de Grace and Perryville in northeastern Maryland.
On the point is a Bombardier-Alstom HHP-8 electric locomotive. HHP stands for high horsepower, and the 8
is shorthand for 8,000 hp. The letters led to a humorous nickname for these machines, "Hippo," although the
resemblance of these sleek high-speed locomotives to the bulky four-legged animal goes no further than that!
Like the more plentiful AEM-7 locomotives (*) along the corridor, the "Hippos" were being phased
out at about the time I made this photograph (from the Havre de Grace side of the river), in favor
of Amtrak's choice of the Siemens ACS-64 "Sprinter"-class locomotives (**) as standard power
along the high-speed mainline linking Washington, New York, and Boston.
Thus, it was nice to spend time at favorite locations along the corridor to be able to
document both the HHP-8s and AEM-7s in the twilight years of their careers.
