Egyptian State 0-4-2 Locomotives in Egypt


Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 10364)

Data from "The Egyptian Government Railways and Locomotives," The Locomotive Magazine, Vol IX (12 September 1903), p. 155. Boiler pressure is an estimate.

Resembling the Mammouth-type goods locomotives delivered by Cail at the same time (Locobase 10363), the design replaced the three small driving sets with two taller sets of drivers, placed the third axle under the footplate, but retained the steam dome well forward and closed by a prominent cap, heavy plate frame, and stubby safety valve stand over the firebox.


Class unknown (Locobase 10476)

Data from E L Ahrons, "Thirty Years of Locomotive Progress in Egypt", Engineer, Volume 118 (11/27/1914), pp 499-501.

Locobase 10475 talks about the 2-4-0T sugar-cane engines the ERA borrowed when a bridge over the Nile proved too fragile to take the standard goods locomotives. At the same time, the railway ordered this trio of smaller, lighter tanks to do the job.
