EM-922 --- This magnificant 90 ton broad-gauge steamer with 'Atlantic' type 4-4-2 wheel array, was built by North British Loco Co. Atlas Works, Glasgow, UK, in the year 1907 as an E1 class loco. This humongous locomotive has the distinction of being the biggest wheels to have ever run on Indian soil with wheel diameter of nearly 7 feet. It was an inspiring engineering feat that the entire loco structure has been assembled without the use of welding technique but through the use of bolts only. This loco is equipped with Waelsharts walve system and comes with standard two cylinder setup and has an inside plate frame. So, the connecting rods as well as all the working mechanism, the wheel turning axle, is actually within the plates. A small turbine was used in the locomotive for generating electricity for the cabin lights - a feature which was later standardised in all models of locomotives.
This loco was an automatic choice to haul many VIP and Royal trains and used to have many names such as 'Lord Clyde', "Roosevelt' and 'Queen Empress'. Apart from which it was used for passenger mail and express trains on the Great Indian Peninsular Railway and later on the North Western Railway. It was converted to a superheated locomotive in 1922 and rebuilt in 1941 at Mughalpura Workshops re-classified from E-1 to EM. Now resting at National Rail Museum, New Delhi as a prime outdoor exhibit. Photographed by Rudranil RoyChowdhury. D.O.P. - 19th September 2018.
