The Württemberg KL of the Royal Württemberg State Railways (KWSt.E.) were steam locomotives equipped with a Kittel boiler for branch line operations.
Originally four locomotives from a series of the Esslingen machine factory were delivered to the West German Railway Company (WeEG). Two of them came to KWSt.E. and were designated as KL 1 and KL 2 . In 1917 a locomotive was sold to the Osnabrück copper and wire works , where it was in use until 1970. The locomotive is now in the German Museum of Technology in Berlin .
history
Order
The trigger for ordering the locomotives was the efforts of the Moselle Railway in 1909 to replace several larger locomotives with smaller locomotives with one-man operation. For this purpose, small locomotives with a standing boiler and double existing control elements were considered. The locomotives should serve the short distances.
Different sources mention four tram locomotives for the WeEG and the Strohgäubahn , others the delivery of four locomotives with the factory numbers Maschinenfabrik Esslingen 3480–3483 .
After a short test, the vehicles were returned to the manufacturer's works in 1910, where some were retrofitted with the Kittel boiler . There are different details about the further use: in one source three locomotives are used for KWSt.E., in another the serial numbers ME 3480 and 3481 are used as KWSt.E. KL 1 and KL 2 mentioned.
Royal Württemberg State Railways
To the KWSt.E. the locomotives were delivered in 1911 and used in light passenger train service in the Tübingen area. The log book of KL 2 has been preserved, from which it can be seen that the locomotive had covered 94,856 km before the next inspection. After a major boiler repair, the machine achieved an annual operating performance of over 90,000 km. In 1916 the machine was stationed in Ulm , where it was in operation until 1917. The fate of the other locomotives is not known.
Private companies and museum railways
In October 1917 the former KL 2 was sold to the Osnabrück copper and wire works , where it was used as number 2 as a shunting locomotive until the end of the 1960s. It was damaged in World War II , but was repaired again. In 1970 it was sold to the German Railway Association in Bruchhausen-Vilsen , where it carried out special trips. In 1972 the locomotive received another general inspection. From 1971 to 1976 it was loaned to the Weserbergland steam railway , where it was only used briefly. The historically valuable locomotive has been part of the inventory of the German Museum of Technology in Berlin since 1984, and in 1985 it was exhibited in Nuremberg on the anniversary of '' 150 Years of German Railways ''.
technology
The locomotives are intended for one-man operation. In the middle of the locomotive is the standing boiler with fire doors on both sides. In addition to the controls, which are arranged on both sides and mechanically connected to each other, the coal reserves and water boxes were evenly distributed over both halves of the locomotive. The train driver could always do his duty alone in the required driver's cab and change his location without having to get out. The driver's cabs are equipped with a transition door so that the train attendants could change to the driver's cab during the journey.
There are different details about the technical equipment: while one source specifies a Serpollet boiler and mentions the Kittel boiler as a modification variant after 1911, the Kittel boiler as the original variant emerges from the operating log of the surviving KL 2 1911. The enlargement of the wheelbase speaks in any case for a different type of boiler than for delivery. The power was transmitted to the two drive axles via two cylinders and an engine with Heusinger control . The performance of the locomotive was specified with a train weight of 100 t on the flat with 55 km / h, on a gradient of 10 ‰ the locomotive could still reach 22 km / h. During test drives, the machines on the Strohgäubahn were able to transport a tensile load of 65 t to 20 ‰ at 15 km / h.
The brake equipment was originally specified with the Hardy brake , which was common on the Moselbahn at that time , after the conversion they had a compressed air brake . In addition, pulling and buffing devices and signaling devices were available.
