The DR class E 170 was a four-axle electric locomotive developed for shunting service , which was built in 1913 for the Spandau port railway . From 1924, the unique piece was used from Berchtesgaden on the Berchtesgaden – Hangender Stein railway line and the Königsseebahn . After the Königsseebahn was converted to a contact wire voltage of 15 kV 16 2⁄3 Hz alternating current , the E 170 01 was converted into a battery locomotive and served until it was retired in 1959.
history
Overhead line operation
The locomotive was built in 1913 by Borsig and SSW for 44,112 Reichsmarks for the Spandau port railway intended for electrification. Since this no longer took place due to the First World War , the Deutsche Reichsbahn took over the locomotive as E 170 01 and stationed it on June 20, 1924 at the Berchtesgaden depot. The locomotive's tasks were to provide trains for the Königsseebahn and occasional freight train services on this route, as well as on the Berchtesgaden – Hangender Stein route until it was closed on October 2, 1938. During one of these missions, the locomotive in Marktschellenberg derailed due to an incorrect switch position.
Battery operation
When the Königsseebahn was converted to alternating current in 1942, the previous area of use was no longer applicable. The Deutsche Reichsbahn therefore decided to convert the E 170 01 locomotive into a battery-powered locomotive. The renovation was carried out in 1942 in the Neuaubing Reichsbahn repair shop . The locomotive kept its original name. From then on, the work tasks were limited to the provision and occasional services of goods on the Königsseebahn as well as shunting services at Berchtesgaden station. In addition, transfer trips to Berchtesgaden mine were carried out on the former local railway to Hangender Stein . After 1945 these services were still intensive, but in the mid-1950s the services continued to decline until the German Federal Railroad decommissioned the locomotive in 1959.
Constructive description
Overhead line operation
The locomotive was a front-end locomotive with a central driver's cab that was common at the time. The electrical equipment was housed in the front end. The main frame was solid and strong. A regular pulling and buffing device was attached to each end . The running gear consisted of two two-axle motor bogies with an outer frame of a simple design. The clearers were trained as snow plows. In the delivery condition, the wheels were covered with facings on the sides, which were removed later. The locomotive had an unsprung, single-sided pawl bearing drive .
The pantograph in a special design, designed for 1,000 volts DC voltage, was originally equipped with three, later with two contact strips. There was also overvoltage and overcurrent protection equipment on the roof. The locomotive was controlled by a manually operated drive switch , which enabled twelve starting and two continuous speed levels. The two traction motors of a bogie were always connected in series , both groups could be controlled either in series (speed steps 1–7) or in parallel connection (speed steps 13–17). The speed steps 8-12 were designed in series-parallel connection. Self -ventilated direct current series-wound motors were used as traction motors .
Originally the locomotive had a Westinghouse brake. The compressed air system consisted of the air compressor , the main air tank and the main air line . There was a signal whistle, a signal bell and the sand spreading device. A spindle handbrake served as the parking brake.
Battery operation
When converting to a battery locomotive, the AFA Hagen batteries were installed in the front end. These consisted of 270 cells that delivered a terminal voltage of 500 volts. Because of the greater load, the frame and the stems had to be reinforced with riveted profile bars. After the conversion with a new drive switch, the control system had twelve start-up and six continuous speed levels.
