The Brohltalbahn VT 50 was a four-axle, narrow-gauge railcar of the Brohltalbahn . It was manufactured by Deutsche Werke Kiel AG in Kiel in 1926 and was intended to streamline the company's operations.

The railcar was converted to a wood gas drive in 1932 and a sidecar in 1939. The car is still there today and is operated by the company as a volcano express .

History and commitment

The VB 50 as a Vulkan-Express

In order to end the mixed traffic on its network, the Brohltalbahn procured a railcar from DWK in Kiel and named it the VT 50 . With the vehicle, the passenger traffic could be carried out according to species and the travel time on the Brohltalbahn between the end points could be halved.

After the advent of the diesel railcar, the VT 50 was no longer economical and was equipped with a wood gasification boiler. This saved fuel and local raw materials could be used. The costs for the benzene operation amounted to around 30 RM per day of operation, they could be reduced to 5.4 RM with the wood gasifier. By 1934, the railcar had driven 430,000 kilometers since it was put into service. Before the conversion, the consumption of benzene should have been 100 l / 100 km drive. With the arrival of further railcars of the KBE 305 ... 311 series and their conversion to diesel engines, the VT 50 was no longer used. By removing the engine, it was converted into a sidecar in 1939.

The car remained in use until the end of regular passenger train service in 1961. With the 11 nm locomotive he was used in the last passenger train on the Brohl Valley Railway. The car was preserved and was used as a route coach.

After the first special trips with the Vulkan-Express were carried out on the remaining stretch of the Brohltalbahn in 1977, this offer was carried out regularly from 1992 by the Brohltal Schmalspureisenbahn (IBS) interest group . The VN 50 was converted into a saloon car for this purpose.

Constructive features

The railcar belonged to the DWK model series V. In this model series, the entire machine system, including its trough-shaped machine support frame in the center of the bogies, was stored in the track sockets for the first time with DWK railcars . The machine system could be exchanged without lifting the car body. In addition, the machine system was freely accessible and exchangeable by lifting flaps. The car body was made of all-steel construction as a rivet construction and had the typical head shape of DWK cars. It was supported by coil springs on the weighing beams of the bogies. The underframe carries the box frame, which is clad with two millimeter thick sheet metal. All sheet metal connections are riveted. The interior was made of plywood.

The gasoline engine transferred its power to a four-speed gearbox via a foot-operated dry clutch . This was switched mechanically with gear shifts and enabled speeds of up to 35 km / h in the individual gears. The inner wheel sets of each bogie were driven by cardan shafts and axle drives. The wheel sets were stored in roller bearings.

Several lamellar coolers were arranged on the roof for water cooling. The passenger compartment was heated by the engine cooling water. The fuel container was also on the roof. The fuel was fed to the gasifier via protected pipes through the natural gradient.
