Egyptian State 2-4-0 Locomotives in Egypt


Class Details by Steve Llanso of Sweat House Media

Class 154 (Locobase 10435)

Data from "The Egyptian Government Railways and Locomotives," The Locomotive Magazine, Vol X (15 January 1904), p. 10. Boiler pressure is an estimate.

These locomotives were originally produced for the Azizah-Mussrieh railway in Turkey, but, as the author of the LM history delightfully, if ambiguously, puts it, "...like many good things intended for Turkey, never arrived there."

What the ERA received were some pretty lusty locomotives, at least in terms of the ratio of grate area and firebox heating surface to overall heating surface. The profile suggested a burly character with outside frames curving over the coupled-axle axle boxes. The author notes that other than the stack and the cab, the design "bore a strong resemblance to Mr Sturrock's Great Northern design of the period."

When Trevithick rebuilt the class in 1887, he removed the compensating beams between the springs of the coupled axles and adopted a straightline boiler. The spark-arresting stack originally intended to control wood-burning byproducts had long since been replaced by a much smaller "chimney".


Class 86 (Locobase 10399)

Data from "The Egyptian Government Railways and Locomotives," The Locomotive Magazine, Vol IX (7 November 1903), p. 268.

Similar to the Medocs in service in eastern France and Italy, these Medocs were built fo the Lombardy-Venetian Railway in Italy and shipped to Egypt. They had large domes placed well forward on the boiler. In service for close to 30 years


Class Class 2 (Locobase 10466)

Data from E L Ahrons, "Thirty Years of Locomotive Progress in Egypt", Engineer, Volume 118 (27 November 1914), pp 499-501. Neilson works numbers were 3918-3929.

Ahrons said that the motion, cylinders, and boiler were exactly the same as those of the Singles, described in Locobase 10456. In addition to Neilson and Company's dozen, Franco Belge constructed 48 at La Croyere and 18 at Raismes.


Class Class 3 (Locobase 20258)

Data from E L Ahrons, "Thirty Years of Locomotive Progress in Egypt", Engineer, Volume 118 (27 November 1914), pp 499-501.
