Class Details by Steve Llanso of Sweat House Media

Class 57.001 (Locobase 1638)

Data from A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966); and from [link] (visited 25 December 2003; later link is [link], last accessed 25 December 2003), the website of Demiryolu, the Turkish train magazine..

Examples were supplied from 1933 to 1937 by Henschel

and Schwarzkopff (BMAG?)

1936 10395-10397 57.017-19

ToT writes that this class was basically the KPEV's G10 0-10-0 (Locobases 1283 and 12575) with leading and trailing trucks added. Perhaps that was so, but areas for both the boiler and the superheater given in the ToT entry are much larger.

Working mostly in the Izmir area where their light axle loading was much appreciated, these "Santa Fes" saw steam out.


Class 57.01 (Locobase 1637)

These tank engines were used as helpers ("banking engines") on a 3% grade between Bilecik and Krakoy.

Two delivered by Henschel (works 20550-557) in 1951, two by Jung (11481-82) in the next year. Data from A[nthony] E[dward] Durrant, The steam locomotives of Eastern Europe (Abbot Newton: David & Charles, 1966) and [link] (visited 25 Dec 2003), the website of Demiryolu, the Turkish train magazine.
