The E9 is a {{convert|2400|hp|0|adj=on}}, A1A-A1A passenger train-hauling diesel locomotive built by General Motors' Electro-Motive Division of La Grange, Illinois, between April 1954 and January 1964. 100 cab-equipped A units were produced and 44 cabless booster B units, all for service in the United States. The E9 was the tenth and last model of EMD E-unit and differed from the earlier E8 as built only by the newer engines and a different, flusher-fitting mounting for the headlight glass, the latter being the only visible difference. Since some E8s were fitted with this, it is not a reliable way to distinguish the two. The E9 has two {{convert|1200|hp|0|abbr=on}}, V12 model 567C engines, each engine driving one generator to power two traction motors.{{cite book |last1=Foster |first1=Gerald L. |title=A field guide to trains of North America |date=1996 |publisher=Houghton Mifflin |location=Boston |isbn=0-395-70112-0 |page=100}}

Engine and powertrain

The E9 uses twin 12 cylinder 567C engines developing a total of {{convert|2,400|hp|kW|abbr=on}} at 800 rpm. Designed specifically for railroad locomotives, this Roots-blown, mechanically aspirated 2-stroke 45-degree V-type, with an {{convert|8+1/2|by|10|in|mm|0|abbr=on}}, bore by stroke, giving {{convert|567|cuin|L}} displacement per cylinder, remained in production until 1966. Two DC generators, one per engine, provide power to four motors, two on each truck, in an A1A-A1A arrangement. This truck design was used on all E units and on MP 7100 and CB&Q 9908 power cars. EMD has built all of its major components since 1939.{{sfn|Pinkepank|1973|pp=13, 26, 106, 124}}{{sfn|Ross|2003|pp=273–274}}

Operation

The E9 powered American passenger and mail trains from the 1950s into the late 1970s. Many of America's finest trains — such as Union Pacific Railroad's "City" fleet, Burlington's "Zephyr" fleet and Southern Pacific Railroad's Coast Daylight and Sunset Limited — had E9s pulling them. E9s and their E7 and E8 kin ran throughout the country on lesser-known passenger trains, Chicago's network of commuter trains and many mail and express trains. As America's passenger train network shrank due to unprofitability, Union Pacific, Rock Island and Illinois Central began using E9s on freight trains while Burlington Northern began upgrading their fleets of E9s with Head-end power and EMD 645 power assemblies for commuter operations in the Chicago metropolitan area into the early 1990s.

Amtrak, founded in 1971, bought 36 E9As and 23 E9Bs from the Union Pacific, Milwaukee Road, B&O and SCL. Amtrak used the E9s until 1979 and converted some E9B units to steam generator and head end power cars.{{cite web |url=http://hebners.net/amtrak/amtE9B.html |title=The E8B, E-9B including heater cars, HEP cars made from E-9Bs |website=Amtrak Photo Archive: an unofficial Amtrak site |archive-url=https://web.archive.org/web/20160326024338/http://www.hebners.net/Amtrak/amtE9B.html |archive-date=March 26, 2016}}{{sfn|Pinkepank|Marre|1979|pp=143–145}}

Surviving examples

As of 1997, 42 E9 locomotives survived.According to Andrew Toppan's list of March 5, 1997, 42 survive. Many of these have been donated to several museums and tourist railroads. A number of railroads keep a small number in service for hauling inspection specials, charter passenger trains, investor tours and other special trains.
