E-7 DIESEL ENGINES

Watch/Listen to the video showing you the sound quality of these engines. We think these are pretty impressive engines. Please remember this is low res video shot in bad lighting. The engine looks and sounds much better in person. The individual sounds can be turned on and off at will using a DCC system or the separate DC Contoller.

Most of the premier passenger trains including the AT&SF "Super Chief," various CB&Q "Zephyrs," Great Northern's "Empire Builder," New York Central's "Twentieth Century" and Pennsylvania Railroad's "Broadway Limited" were pulled by EMD "E" unit diesel locomotives from the 1940's to the 1970's. The largest percentage was the E7's with 428 units produced between February 1945 and April 1949. The railroads developed a love affair for the E units until most passenger trains on major railroads were powered by one of the bulldog nose diesel locomotives. Modelers have long been infected by the same bug as the railroads were.

When passenger trains became too long for a single E7A unit, most railroads added additional E7A's to gain enough power to handle such trains. A few railroads opted to have cabless locomotives built: E7B's, which could be controlled from the A unit. The "B" suffix indicates a booster unit. The railroads that used E7B locomotives included: PRR, Union Pacific, Southern Pacific and New York Central.
