The locomotives 11-28 of Ottoman Railway Company (ORC) were Schlepptender locomotives of the type 1B n2, in several construction series 1869 to 1888 from Sharp Stewart were delivered to the ORC.
The first six copies with the numbers 11 to 16 were delivered to the ORC in 1869. Obviously, they had not only proven themselves in use, but also in terms of long-term operating costs at ORC, because twelve years later Sharp delivered three more identical copies with the numbers 21 to 23. 1884 followed six pieces with the numbers 17 and 24 to 28, the gap in the numbering was finally closed in 1888 with the last three copies with the numbers 18 to 20. As was common with British locomotives at the time, they received an internal engine. The leading running axle with its bearings was in the outer frame used. The British locomotive historian AE Durrant describes the series as "with classic British proportions that would have looked perfectly at home on the GER ."
When the ORC was nationalized in 1935, 6 locomotives came as 23.001–006 to Türkiye Cumhuriyeti Devlet Demiryolları (TCDD), which they decommissioned by 1956. The most recently in Yedikule in Istanbul on the route of the former Orient train employed 23,004, formerly ORC 20 manufactured in 1888 under the serial number 3501, was preserved and is now without a Tender as a memorial in front of the train station Haydarpaşa in Istanbul. The tender is located in the Çamlık Railway Museum .
