The series 5701 (as 57.01 respectively) of the Turkish State Railways (TCDD) is a tank locomotive for pushing services with the wheel arrangement 1'E1 ' .
history
The locomotives were developed as the last new series of mainline steam locomotives for the TCDD. Two were built in 1951 by Henschel and two in 1952 by Jung based on the German DR series 85 . In addition to the locomotives of the former DR class 44 , which were taken over from France and classified as TCDD 56 701–748 , these locomotives are the only three-cylinder locomotives procured by TCDD.
The four machines were stationed in Bilecik . From there, they performed the heavy ramp service as push locomotives on the 16 km long and up to 25 ‰ steep section to Karaköy . This ramp leads the important main line between Istanbul and Ankara , which opened in 1892 as the Anatolian Railway , from the southern coast of the Marmara Sea to the Anatolian plateau . They provided this service until the summer of 1972, after which they were used in shunting operations for a few years, most recently the 57.01 in poor condition (without functional inner cylinder) in Tavşanlı . They were decommissioned by the late 1970s. The first locomotive of this series, the 57.01, was preserved in the Çamlık Railway Museum.
technical features
Compared to the 85 series, their Turkish counterparts received slightly smaller cylinders, but the boiler was made somewhat larger in terms of the grate surface , the firebox and the boiler length. With an operating weight of 136 tons, they are somewhat heavier than the class 85 locomotives. Unusually for the intended purpose in relatively slow ramp operation was the equipment with two narrow smoke deflectors on the smoke chamber next to the chimney. The cow catchers originally attached under the front buffer beam were also unusual for push operation .
Similar to the 85 series, the locomotives were designed with a bar frame. The running gear was also identical to the 85 series in terms of its wheel bases and wheel diameters. The leading and trailing axles were combined with the first and last coupling axles to form a Krauss-Helmholtz frame . The outer cylinders drove the third coupling axle, the inner cylinder the second coupling axle. The central coupling axle was given a wheel flange that was 15 millimeters less .
