Class 121 (Locobase 21181)

Data from "Steam Locomotive Portraits - Anatolian Railway (CFOA Turkey) 2-8-0 steam locomotive Nr. 124 (August Borsig, Berlin)" in Flickr's Historical Railway Images photostream at [], last accessed 2 May 2024 . Works numbers were 5255 in March 1904, 5256-5259 in April, and 5260 in June.

The HRI document gives a rigid wheelbase of 9 ft 6 in (2.9 m), which is unlikely to be the full adhesion wheelbase.

Trains of Turkey's steam locomotive roster does not show this cross-compound sextet. According to a general roster note, that means the class was not taken into the TCDD.

Class 131/45.101 (Locobase 1627)

Data from "45101 to 45115" on the Trains of Turkey website at [], last accessed 9 June 2022. Works numbers were 9496-9501 in 1909.

Trains of Turkey credits the 45.101s with fifteen class members. But that seems to include a later batch of Henschel 0-8-0s that had different specifications; see Locobase 21026.

Class 45.001 (Locobase 1626)

Data from A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966); and "TCDD 45001-062" in Wikipedia at [], last accessed 26 December 2021. Additional data from [] (25 Dec 2003). Works numbers were 1781-1786 in 1927, 1803-1812 in 1928; 1848-1849, 1858-1869 in 1931; 1928-1935 in 1934; 1936-1937 in 1934-1935, 1938-1951 in 1935. Tubize works numbers were 2075-2082 in 1928

Shared boilers, cylinders, wheels, etc. with three other engines delivered as pusher 0-8-0s. The design is said by Demirylou to be a Prussian G8 with a boiler lengthened by 400 mm (15.75"). Nohab's builder's photo shows a stubby, high-boilered locomotive with a Belpaire firebox. These were big, powerful Consolidations by any measure. Delivered with Knorr feed water heaters, the class later received Friedmann steam injectors.

Filling a need for more power, the 45.001s served as the "backbone of heavy freight train traffic until the TCDD acquired 2-8-2s in the later 1930s. The network continued to use 45.001s right to the end of steam operations in 1990.

Class 45.121 (Locobase 1628)

Data from A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966); and [] -- the home site of the Turkish train magazine Demiryolu (consulted 25 December 2003), with the latter preferred. Works numbers were 798-809 in 1912.

Durrant puzzled over why these engines should have proved so popular. Examples were supplied to the Damas-Hama railway by Maffei in 1910, to SCP in 1912, and to the CO in 1924. The were, he complains, "very ordinary little 2-8-0s." (Their charm was likely based on a simplicity of mechanism, more boiler per cylinder volume than the average, a low axle loading ... and having been paid for.)

TCDD absorbed all of them as 45.121-132.

Class 45.501 (Locobase 1629)

Data from A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966); and [] -- the home site of the Turkish train magazine Demiryolu (consulted 25 December 2003), with the latter preferred. Schneider works numbers were 4412-4421 in 1924. Batignolles works numbers wre 2124-2135 in 1924.

Originally supplied to the Oriental Railway by Batignolles and Le Creusot. Eighteen taken into Turkish State Railway service as 45.501-518.
