Est 0.189 to 0.200 were 0-6-0 locomotives for freight traffic of the Chemins de fer de l'Est . They were put in service in 1857 and were retired until 1928. [1]
The machines were of similar design as the Est 0.33–0.120 and were built in the workshops of the Chemins de fer de l'Est at Épernay [1] in 1855–1856. [2] They mainly differed in the wheel diameter, which was reduced to 1.34 m (4 ft 4+3⁄4 in). [2] The locomotives had a Crampton firebox and boiler with a boiler pressure of 8 kg/cm2 (0.785 MPa; 114 psi). Beginning with August 1881 the machines received a new boiler with an increased pressure of 9 kg/cm2 (0.883 MPa; 128 psi), tractive effort increased from 3,861 kg (8,510 lb) to 4,698 kg (10,400 lb), while the weight increased from 27.9 t (61,500 lb) to 28.5 t (62,800 lb). [1]
The machines were coupled with two-axle tenders, containing 6 m3 (212 cu ft) of water and 2.5 t (5,510 lb) of coal, and weighing 22 t (48,500 lb). [3]
The locomotives were given the following names: [4]
The locomotives were used for freight trains, similar to the Est 0.63–0.120 for mixed service. [3] In 1875 the machines were listed at the depots Châlons, Bar-le-Duc, Troyes, Chaumont, Nancy, Epinal, Vesoul and Belfort and were used to run freight trains from Paris to Nancy and to Belfort, from Nancy to Belfort and on branch lines. [3] Later the machines were used on secondary lines and shunting. The last locomotive in service, the Est 0.198, was removed from service in 1928. [3]
