P42 "Genesis" Diesel|
General Electic P42 locomotive is also known as the "Genesis" locomotive.
The P42 is a modern 4200 horsepower passenger locomotive used across the United
States and Canada.
Amtrak's P42 has replaced the EMD F40PH in revenue service. Today they are used throughout the United States and often operated in a mixed consist of Phase IV and Phase V schemes.
The Amtrak P42 locomotive was pre-dated
by the P40, which was originally known as the AMD-103, or "Genesis"
locomotive. "Genesis locomotive" collectively refers to the P40, P42,
and P32. (The P32 is a third-rail capable locomotive that operates only in the
Northeast). The P40 was originally delivered in 1993 with the first order of P42's
following in late 1996 and early 1997. The P40 is a 4000 horsepower locomotive,
while the P42 is a 4200 horsepower locomotive.
Amtrak's P42 and P40 locomotives have virtually replaced the EMD F40PH, once the mainline passenger locomotive of choice. As of today, there are only 6 F40PH's in active service, although additional F40PH's are occasionally called upon in emergencies.
