History and design

The WG design was introduced in 1950; it utilised identical equipment (boiler, motion, springs, tender bogies, and rear truck) as used in the 4-6-2 WP class passenger locomotives. The first hundred units (No.s 8301 to 8400) were built by North British and subcontractor Vulcan Foundry (ten units). Number 8350 was exhibited at the Festival of Britain in 1951.[4]

Locomotives were also sourced from the Société Franco-Belge in Raismes, France,[5] Lokomotivfabrik Floridsdorf in Austria,[6] and from elsewhere in Europe and from Japan. The rolling stock works of Chittaranjan Locomotive Works in West Bengal initially manufactured locomotives from imported parts; by 1953, 70% of the locomotives were domestically produced, and by 1956 the works was able to entirely satisfy the domestic production need for WG locomotives. Production ceased in 1970; the final unit being named Antim Sitara (Last Star).[5]
