Data from E L Ahrons, "Thirty Years of Locomotive Progress in Egypt", Engineer, Volume 118 (27 November 1914), pp 499-501.
This decade of deGlehn compounds were priced at 4,800 pounds sterling each. They used a relatively high compounding ratio while sampling the divided drive qualities of the deGlehn design. Another difference from most Eyptian State locomotives was the installation of larger-diameter, internally finned Serve tubes in the boiler.
