The Idar-Oberstein tram was the tram operator of the Rhineland-Palatinate city of Idar-Oberstein . The only line ran from 1900 to 1956 and connected the two districts merged in 1933. It was later replaced by the Idar-Oberstein trolleybus, which opened in 1932 . In both cases, the responsible transport company was Stadtwerke Idar-Oberstein , the power supply was provided by Oberstein-Idarer Elektrizitäts-AG ( OIE ), a subsidiary of RWE . However , the Idar-Oberstein transport company (VIO) is responsible for today's bus traffic .
The largest city in the Birkenfeld district has had a train station on the Nahe Valley Railway , which connects Bingen with Saarbrücken, in the Oberstein district on the southwestern edge of the city since 1859 . The railway runs upwards in the narrow valley of the Idarbach to the Idar district. Because of the sometimes considerable distances to the train station, an inner-city mode of transport was sought early on.
On November 7, 1899, the Elektrizitäts-AG, formerly Schuckert & Cie in Cologne, founded the Oberstein-Idarer Elektrizitäts-AG. This built a power station and on October 8, 1900 opened a meter-gauge tram that was electrically operated from the start, connecting the two neighboring cities.
The route now turned north into the valley of the Idarbaches and had at the end of the main road at the bus stop Stadtwerke a passing loop . Then it led past the depot through the main road from Idar to the end point at Alexanderplatz at the old industrial hall. A transfer terminal was located there. The route was 3.8 kilometers long.
In 1930, on the occasion of the incorporation of Tiefenstein , four kilometers further north, discussions were held about extending the tram there. Due to technical problems, the Rheinisch-Westfälische Elektrizitätswerk AG , which had been the sole shareholder of the electricity company since 1926, decided to set up a trolleybus route to Tiefenstein. Since then, the new mode of transport has complemented the tram. The trolleybuses were also housed in the tram depot.
After more than fifty years of operation, a renovation was due in 1955. In addition, there were frequent problems with the rest of the traffic in the narrow streets of the city. In addition, the hairpin in Oberstein made operations more difficult. The decision was made to replace the entire tram operation with trolleybuses that could run from the station to Tiefenstein. The Idar-Oberstein tram was shut down on July 29, 1956.
The four two-axle railcars 1–4 were initially available for passenger transport, and from 1907 onwards, the railcars 5–7 (manufacturer MAN and Siemens-Schuckertwerke ) were also available. Railcar 2 was converted into a sidecar in 1925 and a control car in 1928 . The two sidecars 11 and 12 manufactured by MAN in 1900 were also converted into control cars in 1928. The Herbrand sidecars 13-15, acquired from the Kleinbahn Wermelskirchen-Burg used in 1920, were also converted into control cars, but were withdrawn as early as 1930. Thus, the push-pull trains typical for this operation were used from 1928. All vehicles were retired in 1956.
