Data from "Ten-Wheel Compound Locomotive, Bagdad Railway," The Locomotive Magazine, Volume XI (15 May 1905), p. 82. For the railway history, see [] and [

This railway was emblematic of the Balance-of-Power economic and political struggle in the "Near East" at the turn into the 20th Century. See the two websites noted above for detailed discussions of the project. Suffice to say that considerations other than economy or engineering ultimately determined alignments, completion dates, and equipment.
The locomotive itself had a surprisingly heavy-looking bogie, large cab windows with "wind-cutter" fairing, and a pilot that resembled a plow.
