The type Henschel AA12 is a series of four-axle diesel-electric locomotives , which the company Henschel 1960/61 to the Egyptian National Railways gave Egyptian National Railways (ENR). It was sister machines of the more powerful, six-axle type AA16 , 38 of which were built in 1959/60.
History and description
The AA12 was created using licenses from the US General Motors Electro-Motive Division (GM-EMD). With the locomotive ends known as "Bulldog Nose", which appeared for the first time in the EMD E-Series , it belongs to the EMD F7 family like the Victorian Railways Class B 60 and the NoHAB AA16 .
As early as 1957, Henschel had delivered thirteen optically similar locomotives of the KK16 series to Egypt . These two-engine machines were created as freight locomotives for the operation of ore trains. The AA12, on the other hand, was designed for use in front of passenger trains .
Unlike the KK16, the AA12 only had a diesel engine . The 12-cylinder engine of the type 12-567 C from EMD developed 1048 kW. Via a generator, it supplied the power for four electric motors that drove the axles of the two two-axle bogies with the Bo'Bo ' wheel arrangement. With a length over the buffers of 18,972 mm, the AA12 was approx. 2.5 m shorter than the AA16, with a service weight of 88 t, 24 t lighter. The top speed of the AA12 was 100 km / h (AA16: 120 km / h). With their headlights arranged one above the other, their fronts were strongly reminiscent of their US models. The front windows were provided with protective grilles to protect them from falling rocks.
A total of 70 machines of this type were built by Henschel and delivered to ENR. In Egypt they were given the road numbers 3601 to 3670. The locomotives were painted blue and had three parallel decorative stripes in the Egyptian national colors of red, white and black underneath the fan band , which were drawn downwards in a V shape on the fronts.
