The standard gauge tank locomotives WLE 0121-0123 of the Westfälische Landes-Eisenbahn (WLE) were in operation with the private railway until 1971 and were then decommissioned and scrapped.
history
The construction of the locomotives was necessary when the freight traffic at the WLE increased sharply in the mid-1930s . The cement works in the Beckum and Ennigerloh area required larger amounts of additional material from the quarries around Warstein to enrich the limestone found here . These transports could no longer be managed with the locomotives available at the WLE.
In coordination with the mechanical engineering office of the WLE, two locomotives were initially built at the Borsig works in Hennigsdorf in 1937, which were given the road numbers 121 and 122 . The same locomotive was delivered in 1942 with the number 123 .
For these transports, the locomotives had to cope with the Westphalian Semmering between Anröchte and Belecke with gradients of up to 20 ‰ and curve radii of up to 200 m radius. Here the locomotives were able to move a load of 500 t at a speed of 30 km / h.
In 1950 they were given a four-digit number and given a leading 0 in front of the previous numbers . With the dieselization from the mid-1950s, the vehicles were gradually replaced, as the WLE VL 0631-0633 took over the services. Nevertheless, they were still in use for years.
It was not until 1968 that the 0121 and 0123 were scrapped , after they were parked in 1966, which required an inspection . The 0122 followed three years later, during which it still handled special operations in passenger train service. In 1971 it was scrapped as the company's last steam locomotive.
construction
The locomotives were developed as two-cylinder locomotives for superheated steam . They had a conical smoke box door. While the entire construction was made using welding technology, the water tanks were riveted.
The boiler was a welded steel structure, as was the fire box . He had two Ackermann type safety valves . The boiler was fed by a Friedmann type jet pump and a live steam jet pump for 250 l / min each. The locomotive had Müller-Schieber .
The frame made using welding technology was designed as a bar frame . The drive was designed for good cornering: the 2nd to 4th axes were firmly mounted in the frame. The 1st and 5th axes were designed to be laterally displaceable with a deflection of ± 25 mm. The designed as a driving axle middle drive axle had weakened mm by 15 flanges . The locomotive had a wheel tire wetting device . The running axles were connected to the adjacent coupling axles as a Krauss-Helmholtz steering frame.
The locomotive had a sandpit. Five sand downpipes could be pneumatically controlled on each side of the engine. The compressed air was generated by a double-compound air pump type Nielebock-Knorr , with which the bell and the low-pitched steam whistle of the Reichsbahn type were operated. Since the locomotives were intended for both freight and passenger train service, they had a steam heater .
