Turkish State 4-8-0 Locomotives in Turkey

Class 46.001 (Locobase 1630)

Data from [] (visited 25 Dec 2003), the website of Demiryolu, the Turkish train magazine, and D[ennis] Rock Carling, 4-8-0 Tender Locomotives (New York: Drake Publishers, Inc, 1972), p. 68. and serials 79-80 on Table VII [7], pp. 100-101.

These Twelve-wheelers were derived from the Prussian P8 4-6-0, or perhaps more directly, from a Prussian 4-8-0 proposal. As Twelve Wheelers went in Europe, this design had a small grate and a large boiler. Also, the adhesion weight ran relatively high as well.

Although built in batches six years apart, the first ten (Henschel, works #20709-20718) had boilers with two steam domes and two sand boxes arranged dome-box-dome-box from front to rear.

The later batch came in small lots in 1932-1935. The differences between the two were the addition of smoke deflectors on the later engines. Matching bread-load domes held sand (front dome) and collected steam (rear dome).

The engines arrived as follows:

Henschel 1932 22079-81 46.011-013

Krupp 1932 1238-39 46.014-015

Henschel 1933 22205-07 46.016-018

Krupp 1933 1290-91 46.019-020

Krupp 1935 1471-72 46.021-022

Henschel 1935 22738-40 46.023-025

The class were originally bought to work the expresses between Haidar Pasha and Ankara. Others operated in Turkey's extreme south,some on the Taurus Express. At the time, the TCDD rated these as able to haul 315 ton trailing loads up a 1.3% grade at 35 kph (21.5 mph).

They remained in service for decades, moving first to suburban operations, then to helper duty.
