Locomotive for Persia (Iran)
The Final minutes with the Loco Testing in Steam, was of a Class 52 Iranian State Railways Locomotive ( Assyrian Lion with Sword, Arabo-Persian Script on Cab sides.)
4'8-1/2" Gauge (Standard)
The erecting sheds can be seen with a multiplicity of Gauges ( Metre, 3'6", Standard, 5'0", 5'3" and 5'6".)
The Diesel Electric Cab Engine was a design used in most British Colonies and Dominions, usually fitted with English Electric Power Plants, and in Metric, 3'6'' (Colonial) and Latin American 5'6" Gauges.
Nearly all those Skills have disappeared...although the principles are the same today ( Foundry, Forging, Machining, etc) but the Knowledge of Building Steam Locomotives is held by a swiftly decreasing band of enthusiasts.
China (PRC) can still build New Steam Locos to order ( but has not built any for its own railways for nearly 15 years) and India still has active Loco Workshops, but they are mostly into repairs these days. NO other country in the world has the experience/facilities or need for Steam Locos.
Thank-goodness Vulcan commissioned a professional Film Co. to make this explanatory film, short as it is...The Core of the Industrial Revolution, and the basis for today's Engineering Profession ( along with Firearms and Bridge Building).
