The Lenz Type C are meter-gauge steam locomotives with a 1'C1 'wheel arrangement
history
In 1927, the Vulcan locomotive factory delivered three meter-gauge superheated steam locomotives with a 1'C1 ' wheel arrangement to the Danish government office on Als (ABA). Until 1920 the railway was operated by Lenz & Co. , whose house supplier was Vulkan. They were given road numbers 40 to 42.
In 1928 the Greifenberger Kleinbahn (GbKB) in Pomerania also got two similar locomotives, they had the numbers 22 and 23. In 1930 two more locomotives were delivered to the Regenwalder (RKB) and the Kolberger Kleinbahn (KKB), which, like the Greifenberger, were also delivered Kleinbahn, belonged to the association of small railways in the Pomerania region . They were numbered 5 (RKB) and 30 (KKB). Since Vulcan had handed over locomotive production to Borsig in 1928 , these two locomotives were built in Berlin. The Pomeranian locomotives, based on the Lenz types, had a capital "C" after the locomotive number, which led to them being referred to as Lenz type C , the Alsen machines did not have this designation. The C at Lenz was actually intended for three-axle standard-gauge locomotives.
In 1933, the Alsener Kreisbahn stopped operating the meter gauge, the three locomotives were sold to Pomerania, one went to the Kolberger Kleinbahn (40, in Kolberg 31) and two to the Greifenberger Kleinbahnen (41 and 42, they kept their numbers). All seven locomotives were included in the numbering plan of the Pomeranian State Railways in 1940 and numbered as 146–152. Except for the KKB locomotive 30, all locomotives were taken over by the PKP in 1945 and given the numbers Twn1-3631 to 3636, later they were classified as Tyn6-3631 to 3636. Tyn6-3631 and 3632 (locomotive 5 RKB and 22 GbKB) came to the Warsaw supply railways. All locomotives were retired by 1977.
Constructive features
All locomotives had the 1'C1 'wheel arrangement, the running axles were designed as Bissel frames. The frame was a sheet metal frame. There were differences in the chassis. The coupling axles of the Alsen locomotives had a larger distance between the first and second axles than between the second and third, and on the Pomeranian locomotives all coupling axles had the same wheelbase. The Alsen locomotives also had smaller running wheels. The first three locomotives (Alsen) were powered on the second axle, the following on the third axle. The locomotives had Heusinger controls and piston valves.
All locomotives had a steam dome and a sandpit on top of the boiler, the Pomeranian locomotives also had a dining dome in front of the steam dome. All locomotives had a Ramsbottom safety valve . The water tank was housed in the frame, to the right and left of the boiler were only low containers with the filler neck. Behind the cab was a coal box with a vertical back wall. The locomotives had suction air brakes in addition to the throw lever brake, later the suction air brakes were replaced by compressed air brakes. Locomotive KKB 31 also got a compressed air brake for the train, the compressed air tank in front of the smoke chamber was noticeable. The outlet pipe on the Alsen locomotives was fitted with a sloping cladding on the side of the smoke chamber, and on the Pomeranian locomotives with a vertical one. The closed driver's cabs of the Alsen locomotives had a large recess above the driver's cab door, the Pomeranian had a smaller one only the width of the door, but there was a larger side window.
Whereabouts
Two locomotives (GbKB 22 and 42) came to the narrow-gauge railway museum Gryfice , where they have been prepared as an exhibition object. The former Regenwald locomotive was brought to Belgium in 1977, and the IHS took over this locomotive in 1984 . She has been using them on her route since 1990 after processing. In 2008 it was shut down because of a defective boiler. In 2010 a new boiler was manufactured. A work-up is still planned, but the completion cannot be scheduled.
