The electric locomotives of the E 16 series (from 1968: 116 series ) were procured by the Bavarian Group Administration of the Deutsche Reichsbahn-Gesellschaft and were designed for express trains.

history

The locomotives were initially designated ES 1 according to the Bavarian class scheme for electric locomotives, before they became E 16 in the DR numbering plan of 1927. The first series (E 16 01–10) was delivered in 1926, the second (E 16 11–17) in 1927. The third, revised series (E 16 18-21) was handed over to the Deutsche Reichsbahn in 1932 and 1933.

The E 16 11 and 13 were lost in the war, the E 16 12 was retired in 1967 after an accident. With the introduction of the DB series scheme on January 1, 1968, the remaining 18 machines were re-designated as the 116 series. Between 1973 and 1980 the machines were then gradually shut down. On January 31, 1980, the 116 009, the last locomotive of the 116 series, was retired.

technology

A special technical feature is the Buchli drive , in which a high-lying motor drives the axle via an external large wheel mounted in the frame. This fully sprung drive gives the E 16 two different viewing sides, one looking at the Buchli drive, the other looking at the bare spoked wheels. The E 16 is the only German locomotive series with the Buchli drive, which was much more widespread in Switzerland and France (e.g. SBB Ae 3/6 I ). To compensate for the drive masses arranged on one side, heavy equipment parts also had to be installed asymmetrically and off-center in the engine room.

Another special technical feature is the control of the E 16, which manually controls a low-voltage slide switchgear (also known as a flat track selector), the level selector of which consists of contact blocks that are assigned to a straight track. These 18 contact blocks (corresponding to the 18 continuous speed levels) are connected to the individual transformer taps. A 'slide' main and secondary contact then slides down the respective step with each actuation, whereby the previous contact always touches the next higher step. The resulting transformer winding short-circuit of the half-stages is dampened by the transition resistors in the transformer tank. This enables an almost jerk-free start-up. Accordingly, the train driver was only allowed to stand in the half steps for a few seconds, as otherwise the transition resistors would heat up too much or even be destroyed. Since the selector is not a circuit breaker, however, eight load switches (one pair due to the very high currents per drive motor), which are arranged to the right and left of the slide, switch off the current during the switching process by opening and closing again. This slide switchgear , which was first used in this form on the E 32 , was further developed into the later high-voltage switchgear N28h and N28i of the standard electric locomotives . There, however, the transition resistors were built air-cooled on the transformer and the tap selector closed under oil for better insulation against leakage currents. The BBC was responsible for both developments.

The following class 116 locomotives have been preserved:
