Turkish State 2-6-0 Locomotives in Turkey


Class Details by Steve Llanso of Sweat House Media

Class 34.001 (Locobase 1616)

Data from A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966). Additional data from [link] (25 Dec 2003).

These engines were built in two batches. Hanomag and Henschel delivered 201-211 to the Chemin de Fer de Ottoman Anatolien (CFOA) and 611-622 to the Baghdad Railway. (623-626, 631-633 followed in 1914).

To reduce the axle loading to a more acceptable 29,762 lb, machiniists on the CFOA inserted a small carrying axle between the second and third set of drivers, which were widely spaced. These then could be described as 2-6-(2)-0, wrote Durrant. (Given where it was, perhaps 2-4-(2)-2-0 might better represent the odd placement.) In any event, those modified carried the axle to the end of steam. This class was later redesignated 34.001-018 and 34.046-048.


Class 34.01 (Locobase 1614)

Check this data, because it doesn't fit with anything else.

To A[nthony] E[dward] Durrant, The steam loc, "their large wheels [sic] spelt 'passenger engine' and their first duties were almost certainly the Haydarpassa suburban service. After TCDD formation, eight were renumbered 34.01-08.


Class 34.041 (Locobase 1617)

Built for the Baghdad Railway. Five came into the TCDD as 34.041-045.

Class 34.051 (Locobase 1618)

Data from A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966); and [link] (accessed 1 January 2003) -- later redubbed [link] (last accessed 25 December 2003). NOHAB works numbers were 1838-1847 in 1930.

Ten delivered by Nohab in 1930, eight more by Henschel and Krupp in 1933-34 for operation on secondary lines.

Photos on the latter site show a true Mogul with high-pitched boiler.
