Ottoman Railway / Turkish State 2-8-2 Locomotives in Turkey

Class 46.051 (Locobase 1631)

Data from A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966); "TCDD 46 051-061" in Wikipedia at [], last accessed 26 December 2021; and [] -- the home site of the Turkish train magazine Demiryolu (consulted 25 December 2003). Works numbers 23135-23137, 23654-23661

Operated between Ankara and Haydarpasa pulling 400- to 500-ton trains. "[T]ruly eminent machines," wrote Durrant, "better really than the Germans built for themselves!" (Henschel's design was based on the DRG's Baureihe 41, but had taller drivers.) Cylinder bore and stroke was nearly "square", as was true for many Turkish classes.

Note that the rigid wheelbase on these machines was 3.8 meters (12 ft 5 1/2"), which suggests a Krauss Helmholz truck uniting the front pony truck and the first driving axle.

Class 46.101 (Locobase 1632)

Data from "Ottoman (Smyrna-Aidin) Railway - Mikado (2-8-2) Type Locomotive", Melesco Superheater Company, Ltd Brochure, p. eleven [sic]; "New Locomotives for the Ottoman Railway", Railway Gazette (12 July 1929), in p 80; A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966); and "46101 to 46106" on the Trains of Turkey at [], (first accessed 25 December 2003, last accessed 27 March 2021. ) Works numbers were 3993-3996 in 1929 and 4073-4074 in 1932.

Built for the ORC to work the Smyrna-Aidin line, these engines had a Belpaire firebox, superheaters, piston valves, and outside constant-lead radial valve gear. Durrant, writing in 1966, commented "Although remarkably small for a 2-8-2, they do good work and are still around today ..."
