The four locomotives that were registered as E 03 were 19.500 mm long and weighed 112,0 tons. They were manufactured until the transportation exposition in Munich in June of 1965. Interestingly enough the E 03 002 was already consigned on February 11 1965 in a festive celebration with the plates of the E 03 001 to the DB. The sustained power output of the E 003 was 5.940 kW, the pulling power was 314 kN and the top speed was 200 km/h. During the transportation exposition test runs with a good PR effect were conducted with modern wagon stock between Augsburg and Munich with speeds of up to 200 km/h. After the exposition the locomotives were still used in the express train traffic and logically especially in front of fast and heavy TEE trains. When the serial machines BR 103.1 commenced regular service, the star of the pre series machines started to sink. In 1979 they arrived in test service in Munich and Minden.
