Data from E L Ahrons, "Thirty Years of Locomotive Progress in Egypt", Engineer, Volume 118 (11/27/1914), pp 499-501.
Once Henschel's Class 30 0-6-0 goods locomotives broke the ice and introduced Walschaerts gear, virtually all subsequent design used that outside constant-lead radial valve gear. Ahrons explained that earlier trials with outside cylinders "led to frequent trouble with the slide bars, owing to the dusty nature of the road bed." In more recent years, however, permanent way upgrades on main and principal branch lines had included ballasting with broken stone.
The low drivers suggest a lower speed, but certainly increased the power of this relatively short-coupled, short-stroke design. It was used for hump shunting (switching) in the ESR's Alexandria yards.
