Introduced in 1956 as class E10, the 110.1 series was the first modern, post-war design introduced by the DB and was intended for principal passenger services. Development of this class followed the introduction in 1952/53 of five prototype locomotives (10 001 to 10 005) incorporating various forms of control equipment and transmission. Extensive trials with these machines led to the appointment of Krauss-Maffei and Siemens Schuckert Werke as principal contractors for the production run. Construction was shared by Henschel and Krupp, with electrical equipment provided by the Allgemeine Elektrizitäts Gesellschaft (AEG) and Brown Boveri Company (BBC).
In 1963, the E103 (now 110.3) variant appeared and the original series was reclassified as E101. Performance and equipment of this later series is similar to the 110.1 but the body design has a cleaner and more aerodynamic treatment. Two of these units, E10 299 and E10 300 (now 110 299 and 110 300) were regeared experimentally for 125 mph (200 km/h) running in 1963. During the previous year, six locomotives were modified before delivery for 100 mph (160 km/h) running on TEE services and were appropriately painted red and beige. Designated E1012 and numbered E10 1265 to E10 1270, these were joined eventually by 25 similarly adapted units to form the DB’s class 112. Gaps occurring in the class 110.3 number series are those originally allocated to the 112s. The important class 139/140 development of this design appeared in 1956.
