Class Details by Steve Llanso of Sweat House Media

Class 161/44.103 (Locobase 1624)

Data from [], last accessed 5 September 2021. Works numbers were 3359-3362 in 1913.

Trains of Turkey has very little to say about this quartet of eight-coupled goods locomotives. Compared to the 1910 Henschel nonet (Locobase 1925), the 161s presented about the same grate area and generated very similar starting tractive effort, but slightly less evaporative and supeheater area.

When the nationalized Turkish Railway (Tnrkiye Cumhuriyeti Devlet Demiryollari-TCDD) stood up in 1929, the 161s took class ID 44 (4 total axles, 4 driving axles) 103.

TofT reported that the class had left service "by 1956".


Class 201/44.501 (Locobase 1625)

Data from [] (25 December 2003); later moved to Trains of Turkey website at [], last accessed 5 September 2021. Henschel works numbers were 10059-10061 in 1911, 11334-11336 in 1912, and 11723-11725 in 1913.

Built for the Oriental Railway and taken into the TCDD in 1929 as 44.501-509


Class 201/44501 (Locobase 21026)

Data from "44501 to 44509" on the Trains of Turkey website at [], last accessed 9 June 2022. Works numbers were 10059-10061 in 1910, 11334-11336 in 1912, and 11723-11725 in 1913.

These eight-coupled goods locomotives resembled the Prussian State G8 class.


Class 44.001 (Locobase 5832)

Data from [] (25 December 2003); and [], last accessed 5 September 2021.

The engines specifically ordered for Turkish use were identical to the Prussian Railways G8 locomotive. Locobase 1278 provides the best match for the specification.

Most were supplied during the First World War to the CFOA. But TrainsofTurkey showed tThe Turkish G8s having ":a very complicated history and not all the records are available to trace back every unit".

TCDD's motive power roster eventually counted 83 G8s, but TofT could verify the origins of only 21.Two each would be ascribed to Henschel and Schishau,10 to a 1924 batch from Linke Hoffman to the Chemins de fer Smyrne Cassaba et Prolongements (the Smyrna-Cassaba, six built in 1910-1913 and supplied to Damas Hama et Prolongements (DHP), and two more that originally served the Prussian State Railways.


Class 44.091 (Locobase 1623)

Data from A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966); and "New Rolling Stock, Ottoman Ry," The Locomotive Magazine, Vol XIII (15 February 1907), p. 38.

Used in Anatolia to climb the grades from Izmir to the interior. LM reported that they ran between Smyrna and Aidin. The design cried out for a leading truck and had outside, inclined cylinders that appeared to have been bolted on, but was otherwise a handsome straightforward engine with Belpaire firebox, short capped stack, a full cab with arched windows. Side play of 3/4" to the rear axle allowed the locomotives to negotiate sharp curves; the coupling rods were fitted with ball joints.

TCDD numbered them 44.111-114 and later 44.091-094.


Class 44.101 (Locobase 5833)

[] (25 Dec 2003) - the website of demiryolu, the Turkish rail magazine..

These were two ex-KPEV G8.1 engines operated by the Turkish Army and later taken into the TCDD.

The data seem incomplete as the Prussian G8s had superheaters and the ToT table says "n/a".
