The class Щ (German transcription Schtsch) of the Soviet Railways (SŽD) was a class of Russian narrow-gauge locomotives for use on forest railways. Several locomotives came to Germany during the Second World War . One copy was taken over by the Deutsche Reichsbahn and was later designated as 99 4541 .

history

Some locomotives of the series Щ came to the Căile Ferate Române in Romania . There they were used with their original numbers. Three of these locomotives, 159-420, 159-331 and 159-334, were parked on the Saxon narrow-gauge network after the end of the war. Due to the lack of locomotives, they should be made operational again, which only happened with the 159-420, the other two (built in 1936) were parked in Mügeln until 1955 and were then scrapped.

99 4052

The 159-420 was given the number 99 4052 by the Deutsche Reichsbahn and came to Wilsdruff on February 20, 1949 after repairs at the Zittau depot, which lasted two and a half months. Until her interim examination at Raw Görlitz, she was deployed for a total of 204 days and covered 20,363 km. From May 29, 1951 it belonged to the Bad Schandau depot, where the machine was used as a brake locomotive for the dismantling of the narrow-gauge line Goßdorf-Kohlmühle-Hohnstein in Saxon Switzerland . On August 4, 1951, it was transferred to the Thum depot and was used for shunting work and the transfer trips to the local paper mill. According to the operating log, the locomotive ran 196 days up to May 1952 and covered 26,913 km.

On February 8, 1953, she came to the Eisenach depot for repairs, where she received a compressed air locomotive brake. From April 1, 1953, it was under the Trusetal locomotive station in Meiningen depot. Up to January 1957, the locomotive was used on the Trusebahn on 469 days and covered 66,161 kilometers, which is documented by the logbook. In the period from April 21 to August 25, 1958, it was prepared in the Raw Görlitz for its use in the Rathenow-Senzke-Nauen district railway and received its final number 99 4541. In connection with the suspension of passenger traffic on this route it was turned off on January 24, 1961. On October 19, 1961, the locomotive came to the Jüterbog depot, where it was in service for exactly 100 days until November 14, 1962. On February 15, 1963, after an investigation in Raw Görlitz, she was transferred to Burg to the former small railways of the Jerichow I district and was used there on 20 to 28 days a month. After an interim inspection at the Burg depot in March 1964, the locomotive was only rarely used because Reko locomotives had already taken over their work. It was last used in August 1964, served as a reserve locomotive until October 1964 and was parked on October 20, 1964. On March 5, 1965, the locomotive was in the z-position and on November 4, 1965 it was decommissioned in Raw Görlitz and dismantled the following year.

technical features

The locomotives had a Heusinger control . The third axle was used as a driving axle and had no flange for better cornering . The frame was a sheet metal frame. The locomotives had a Ramsbotton safety valve on the boiler in front of the driver's cab, in front of it there was a round sandpit, and in front of it there was a steam dome in the direction of the chimney. The boiler was fed with two steam jet pumps. The supplies were carried in a two-axle tender and in side water boxes. At the DR, the locomotive had a Knorr type air pressure brake, and a reel for the lever brake was available as a train brake .
