Product Features and Details
Prototype: German Federal Railroad (DB) class E 50 freight locomotive. The locomotive looks as it originally did around 1960.
Model: Both trucks powered. The wheel treads are dark nickel plated. Length over the buffers 88 mm / 3-7/16".
Highlights:New tooling based on the prototype of the "Power House".
50 Years of the E 50 ... The German Federal Railroad's new construction electric locomotive program at the beginning of the Fifties also envisioned a heavy freight locomotive in the E 50, which was intended as a replacement for the E 94. The E 50 was designed first for heavy freight service on steeply graded routes; hence, it was supposed to provide performance that exceeded all electric locomotives previously built in Germany. Embedded in the total program of development for the new standard design electric locomotives, the lead management for the E 50 was given to the consortium of Krupp/AEG. The nominal power at 80 km/h / 50 mph was 4,500 kilowatts / 6,035 horsepower; the continuous power at 70 km/h / 44 mph was 4,218 kilowatts / 5,656 horsepower. With a view to the future, the E 50 was already designed for a maximum speed of 100 km/h / 63 mph, which could not be used to advantage for a long time in freight service because of older freight cars not suitable for such speeds. The higher performance requirements could only be achieved with appropriately larger designs of the essential components compared to the components for the other standard design electric locomotives. The transformer and the blower motors in particular required more room in the E 50. Three-axle trucks (C-C wheel arrangement) had to be installed so the axle load of 21 metric tons was not exceeded. The long trucks meant that the frame for the body had to be longer, so that the E 50 was about 3 meters / approximately 10 feet longer than the E 10/E 40. The first units were placed into service beginning in April of 1957; the last E 50 locomotive was placed into service in July of 1973. A total of 194 locomotives were built. As with the other standard design electric locomotives, the E 50 (designated as the class 150 starting January 1, 1968) underwent numerous structural changes and improvements. The most noticeable changes externally were the removal of the rain gutters, the handrails on the ends with grate-style footrests, as well as the equipping of the locomotives with the "Klatte" design vent grills. The technical progress on the E 50/150 did not stop at the turn of the century with the class 152 and 185 electric locomotives being placed into service. In 2003, the last of the class 150 was taken out of service. Only two units remain preserved as museum locomotives for future generations.
Model & Prototype Information
Prototype: The Class E 50 is an electric heavy freight locomotive built for German Federal Railways between 1957 and 1973. It belongs to the Einheits-Elektrolokomotiven (standardised electric locomotives) program and was built as heavy freight hauler to be used on the increasingly electrified main lines of the DB, where they were set to replace the steam traction. In 1968 the series was redesignated as class 150 (E50). Originally the Class 150 was also suitable for passenger service, however it did not have any steam or electric heating capability for the passenger coaches. In 1957 the first locomotive, 150 001, was delivered by AEG and Krupp. Altogether 194 locomotives were ordered and delivered. To date, the Class 150's starting tractive
effort of 450 kN (100,000 lbf) remains unparalleled on German rails, in fact it was very close to the breaking force of the chain couplings used at the time of its production. Some engines were therefore fitted with automatic coupling (type unicupler AK69e) to haul heavy ore-trains. By 2004 all class 150 locomotives except 150 091 and 150 186 were scrapped.
