Class E 41 - The Firecracker of the German Federal Railroad. A total of 451 class E 41 locomotives were purchased between 1956 and 1971. For several decades, they left their stamp on more than just the commuter service from the Bavarian Alps to the German coast. This successful design can be considered as a general-purpose locomotive, since it was used as motive power for practically every kind of train service during its long service life. It did not last long in the rigorous S-Bahn service, because it did not have electric brakes required for it. Its traditional task remained commuter service, in particular in push/pull operation with "Silberlinge / Silver Coins" commuter cars. Due to the required low axle load distributed over 2 two-axle trucks, the E 41 could be used with no problem on electrified branch lines. The 4 traction motors on the locomotive represented a further development of the ET 30, and the Siemens-Schuckert Plant / SSW was responsible for the drive gear. They equipped the E 41 like the other standard design locomotives with a rubber ring drive gear system. The oil-cooled transformer was equipped with a relay layout on the low voltage side, which was the source of a characteristic noise on the class E 41. This locomotive soon picked up its nicknames "Champagne Cork" or "Firecracker" on the German Federal Railroad. More than a few railroad passengers, upon hearing this sound, thought the locomotive was damaged and were more or less irritated about it. The maximum speed for this 15.62 meter / 51 foot 3 inch long locomotive was 120 km/h / 75 mph. When the German Federal Railroad raised the maximum speed for express trains at the end off the Fifties to 140 km/h / 88 mph, E 41 locomotives coming after that were only painted in green, since the elegant blue was reserved only for fast locomotives in long distance service. During its entire service life, the class E 41, from 1968 on the "141", had double-arm pantographs. Otherwise, it changed externally as the result of rebuilding and ran in Germany from the Alps to the North with three or five lights at each end, with or without rain gutters, with rounded or square cooling vents and in the color schemes that changed over time. The train safety systems were also adapted along the way and the "firecracker" was considered a proven, reliable design right up to the end of its service.
