The CSD series 498.1 was for heavy express train service designed Train Locomotive of the former Czechoslovak State Railways (CSD). The locomotives, which have been further developed from the tried and tested ČSD class 498.0, represent the pinnacle of steam locomotive construction in Czechoslovakia and throughout Europe. Because of their elegant appearance, they were nicknamed Albatros jednička by the operations service .
history

As a further development of the 498.0 series, the most modern construction elements were used in the construction of the 498.1 series, which were collected worldwide in the construction of steam locomotives. The class 498.1 together with the French 242 A1 and 241 P from André Chapelon represent the absolute highlight in the development of steam locomotives in Europe.
Škoda in Plzeň delivered a total of 15 locomotives to ČSD between 1952 and 1954. Initially, the locomotives were located in Žilina , Praha and Přerov , later all 15 machines were combined in the Bratislava depot . The locomotives were used primarily in front of the international express trains weighing up to 1,000 t.
The range of services provided for trains with 600 t to be carried on the flat at 116 km / h and on a gradient of 14 ‰ at 30 km / h. The possible maximum speed of 120 km / h was comparatively low, but this was completely sufficient for the operating conditions on the hilly lines of the ČSD. The locomotives were also designed for higher speeds; on August 27, 1964, the 498,106 reached a speed of 162 km / h during test drives on the Velim test ring .
With the electrification of the main Czechoslovak main railways, the locomotives lost their field of operation and they were retired by the summer of 1973. The 498.104 remained as an operational museum locomotive in Bratislava Východ , the 498.106 as an exhibit in the National Technical Museum in Prague and the torso of the 498.112 in Louny .
technical features
The locomotives received welded boilers with a combustion chamber and steel fire box, roller bearings on all axle and rod bearings, mechanical grate loading , Kylchap double blow pipe and shaking grate.
