The O&K MV 8 Schmalspur series are two-axle diesel locomotives with hydraulic power transmission that were built by Orenstein & Koppel for various narrow-gauge railways. Ten locomotives are known that went into operation from 1957 to 1961. Some locomotives are still available in 2020.

history

The locomotive was developed by Orenstein & Koppel at the Dortmund-Dorstfeld plant as a narrow-gauge variant of the O&K MV 8 series from the first post-war program.

Wandsbeker Industriebahn 2 and 3

The first locomotives of the series were delivered as meter- gauge locomotives to the Wandsbeker Industriebahn in October 1957 and were located there until 1967. They were equipped with multiple controls and were often used as twins in trolley traffic . In this form, the locomotives could move freight trains weighing up to 300 t.

Then the locomotives were handed over to the Steinhuder Meer-Bahn and were named DL 101 and 102 there . In 1970, the two locomotives carried the last train on the narrow-gauge line.

While the DL 101 is available at the Ulm Railway Friends after a temporary job with the Appenzeller Bahn , the second locomotive was sold to Togo , where its track is lost.

RSE V 11 – V 13

The next locomotives for the Bröltalbahn were those built for the 785 mm gauge. They were in service until the cessation of operations on the route. All three machines were transferred to the Zillertalbahn after being changed to the Bosnian gauge .

The last machine built was taken over by the RSE Museum Asbach as a rollable exhibit, the former RSE V 12 is located as the D 12 on the Zillertal Railway. The third locomotive donated spare parts, its whereabouts are unknown.

Hohenlimburg small train 1–5

With the extension of the concession of the Hohenlimburg small railway, a demand was made for the use of diesel locomotives to replace the steam locomotives.

Four locomotives were delivered in 1960, followed by a fifth locomotive in 1961.

The locomotives have proven their worth in freight transport in the Nahmertal with only rolling wagons through the narrow streets with numerous factory connections with often tight curve radii. For almost 25 years they carried out the entire operation on the small railway. The V4 locomotive was parked in 1976 and continued to be used as a spare parts donor.

After operations ceased in 1983, the V1 and V5 were used on a meter-gauge railway operated by Transport en Commun in Belgium and were still in operation there in 2011. The V2 and V3 locomotives are on the Märkische Museum Railway . The V4 , which had already been taken out of service before the shutdown , was externally refurbished and erected as a memorial in Hohenlimburg at the end of the 1980s .

Constructive features

The locomotives, which Orenstein & Koppel and Lübecker Maschinenbau AG collaborated with , have a strong inner frame.

The machine system consists of a motor from Orenstein & Koppel and a hydraulic gear from Voith , followed by a reversing gear from Orenstein & Koppel. The power transmission takes place via a off-axis group jackshaft and fuels, as well as rods. In the case of locomotives for the meter gauge , the transmission takes place directly on the crank pins of the wheels, for the gauge of 785 mm and below it is done with the help of Hall cranks . With the locomotives, the Hohenlimburg Kleinbahn first used the Knorr type compressed air brake and a pneumatic multiple control . They are equipped with a safety driving circuit, which enabled one-man operation with double traction , whereby the locomotives were coupled to the driver's cab.

Special

In addition to these locomotives, a standard-gauge variant was built, of which no dimensions are known.
