The EMC E5 is a 2000hp, A1A-A1A passenger train-hauling diesel locomotive manufactured by Electro-Motive Corporation, and its corporate successor, General Motors' Electro-Motive Division (EMD) of La Grange, Illinois. It was produced exclusively for the Chicago, Burlington and Quincy Railroad (“The Burlington Route”), and its subsidiaries between 1940 and 1941.
The E5 was distinguished from the otherwise very similar E3, E4 and E6 by being clad in polished stainless steel to match the Burlington's Zephyr trains. It also featured unique small grill-like ornamentation on both sides of the upper headlight. Like the other pre-war models in the E-series, the E5 had a sloping “slant nose” design and was equipped with two headlights—a regular stationary headlight above a gyrating Mars signal light. The E5 was the sixth model in the EMD E-unit series.
The E5 was powered by twin 12-cylinder prime movers, developing a total of 2000hp at 800 rpm. Designed specifically for railroad locomotives, the mechanically aspirated, two-stroke, 45-degree V-type engine, with an NaN0NaN0 bore by 100NaN0 stroke, giving 567cuin displacement per cylinder. This engine design remained in production until 1966.
The E5 was originally intended to look very different with the cab section looking very similar to the streamlined diesel passenger trains that the CB&Q was famous for. Power for the locomotive's traction was provided by two direct-current generators, one for each prime mover. This generators powered four traction motors, two on each truck, in an A1A-A1A arrangement. This truck design was used across all E units, as well as on the MP 7100 AA6, CB&Q 9908, and CRI&P AB6 power cars. Since 1939, EMC/EMD has manufactured all of its major components.[1]

Only one E5 unit of the original 16 built survives today. The last surviving EMD E5 diesel, CB&Q No. 9911A Silver Pilot, is owned and operated by the Illinois Railway Museum in Union, Illinois. The locomotive was last used on the Fort Worth and Denver Railway (a CB&Q subsidiary) for the Texas Zephyr. It is now paired with one of the Burlington's Nebraska Zephyrs, a 5 car, articulated, stainless steel passenger train from 1936.
This equipment has been featured in several film productions, including the 1992 movie A League of Their Own and the 2006 movie Flags of Our Fathers. E5 9911A Silver Pilot was used with 4 stainless steel passenger cars relettered to resemble the Zephyr trainset. 9911 is equipped with dual horns, which is a WABCO E2 and a Leslie Controls RS2M.
