Steam enginesOn this page... (hide)
Warning: non TCDD steam loco (industrial or otherwise) and loco out of inventory before TCDD was founded are not in listed. OverviewDuring the Ottoman time, the various private companies procured their motive power mostly from the home country of their stockholders. Then, having no national engines manufacturing, TCDD continued to purchase imported engines. Consequently Turkish engines are coming mostly from Germany, England, France and United States. TCDD relied on existing proven design and the western railway enthusiasts will often recognize engines already seen at home. The Turkish network is quite demanding. It is a mountain network with steep gradient and sharp curves. On the Anatolian plateau the average altitude is near 1000 m. The weather is hot and dry in the summer. But it is often forgotten that, inland, the winter is very cold and with a lot of snow. For these reasons, Turkish engines are "small wheels", four and then five driving axles became quickly the norm, the first Decapod (1'E) where used in the 1920's. Since speed was not feasible, the same engines could be used on freight as well as passenger trains and most of the engines are of "mixed" type. Double heading plus banking was common: it was not rare to see four Decapods working on the same train. But articulated engines were not successful in Turkey: one Garratt have been tried and a few Mallets have been used in the 1920's but they were taken out very quickly. Mallet should have been very successful but my guess is that the lack of capital finance prevented TCDD from buying them. Maybe someone can provide additional explanation? Engines numberingThe numbering scheme used by TCDD for its steam engines relies on the number of axle:
For example:
As seen above, TCDD is not using a strict "class" number or designation for each type of engines. However in most cases, serial numbers in sequence are usually used for identical engines. Therefore, the first numbers of the series are used as a proxy for class number. For example 56301 refers to the Vulcan Foundry Decapods, 56501 is the type BR52 Kriegsloks. Unfortunatly, there are several case of identical engines numbered in non following sequence. A classic example is the CFOA 1'C numbered by TCDD 34001 to 34018 and 34046 to 34048. The serial numbers are not indicating the years of acquisition. For example, the 56301 are 1948/49 engines whereas the 56911 are 1926/27 engines. Numbers are not indicatives of the gauge either. And of course, like any self-respecting railway, TCDD as some overlapping numbers, missing numbers and other oddities! First World WarSoon after the start of the First World War fightings, The Ottoman Empire signed an alliance treaty with Germany (august 2, 1914) and declared war to France and UK on November 5, 1914. This started a time of great turmoil for Ottomans railways. The Ottomans had to fight on multiple fronts several thousand kilometers apart (Dardanels, Baghdad, Palestine, Erzurum, …) and the meager railways resources were soon stretched out. The German provided assistance to complete the Baghdad Railways and they send war engines, mostly G8 but also G51, G54, G71, G72 and G81. Some British ROD 060 GWR Dean Goods found their way to the ORC and then to TCDD. They were presumably shipped to Turkey when Istanbul and part of the CFOA was under British control in 1918/1922. Second World WarTCDD kept expanding its network throughout the 1930's opening important route (Sivas line in 1932, Zonguldak in 1937, Erzurum line in 1939). Thus motive power needs greatly increased and TCDD placed orders for locomotives in UK and Germany. The beginning of the Second World War disturbed the delivery of these new engines. Turkey remained neutral during the Second World War and the Turkish government played smartly the odds and found itself courted by the British and the German. Both agreed to deliver war engines to TCDD. Consequently, some of the most popular war engine could be seen working in the 50's in Turkey:
On top of all, these engines were working with units from world war one (mostly German G8), and at the Syrian Border, they met DHP Austerity 2-10-0! See also:

Steam railcarTCDD had one class of steam railcar. Reference of this odd unit is given here.
Articulated steam engine in TurkeyDespite a network combining sharp curves and steep gradients, TCDD never acquired articulated steam engines and stick to Decapods. Private companies before TCDD experimented some articulated locomotives. It is likely that some of these engines were still in operation when TCDD took over from their previous owners. TCDD itself reports some large engines to UIC. UIC statistics for TCDD, engines with 6 or more driving axles:
However, we have no evidence of TCDD actually giving inventory number to any of these locomotives.
The Russian army used briefly some 1067mm gauge Garrat on the eastern front during WW1. |
