It was designed for the side- busbar network of the Southern Region and could only be used there.
From the series with the wheel arrangement wheel arrangement 24 machines created with numbers E5000 through E5023, E5000, the E5024 was renamed 1,962th In the Total Operations Processing System (TOPS) they were given the class 71 series designation in the 1970s. Power was drawn from the busbars via sliding contacts . They were also equipped with a pantograph for safe operation under an overhead contact line on sidings .
The Class 71 was a powerful locomotive with an hourly output of 1900 kW. The top speed of the 78.24 t machine was 145 km / h. Depending on the area of application, it ran with 650 V (eastern and central area of the "Southern Region" network) or 750 V direct current (western area). At first the machines were painted green, later they were given a blue livery with yellow fronts.
The Class 71 was mainly used in freight traffic , but it also pulled high-quality passenger trains such as the Golden Arrow and the Night Ferry . The decline in freight transport by rail led to the shutdown of 10 machines in the 1960s. In 1967/68 10 units were converted into diesel-electric locomotives and assigned to the HB series (later: Class 74 ). The remaining HA were renumbered in the TOPS system in 71001 to 71014 and shut down in November 1977. The 71001 locomotive (formerly E5001) escaped scrapping, it was preserved by the National Railway Museum .
