what is it?

The E7 is a 2,000-horsepower (1,500 kW), A1A-A1A passenger train locomotive built by General Motors' Electro-Motive Division of La Grange, Illinois. 428 cab versions, or E7As, were built from February 1945 to April 1949; 82 booster E7Bs were built from March 1945 to July 1948. (Circa 1953 one more E7A was built by the Los Angeles General Shops of the Southern Pacific by rebuilding an E2A.) The 2,000 hp came from two 12 cylinder model 567A engines.

  • power 1.5 MWpower output
  • weight 143 tin working order
  • built 429made in total

Bars compare against all trains: 600 km/h (maglev), 1,700 seats; power, weight and number built on a log scale up to 20 MW, 1,000 t and 20,000 built.

fun facts

  • First built 81 years ago, in 1945.
  • Top speed is 1.4× a car on the Dutch motorway (130 km/h).
  • At full speed it would cover Amsterdam–Utrecht (≈ 40 km) in 13 minutes.
  • 1.5 MW is about 18 family cars (~85 kW each) flat out.
  • Weighs about as much as 24 African elephants (~6 t each).
  • 21.6 m long: about 5 cars parked nose to tail.

multiple unit: A self-propelled train: motors are spread under the passenger cars, so no separate locomotive.
