The Class HG (Heavy Goods) is one of seven standard classes of steam locomotives designed by the British Engineering Standards Association (BESA) for use in the British Raj in the mid-1900s.
This design was used by various railway companies of the British Raj, later passing on to Indian Railways and Pakistan Railways after the partition, the latter of which continued using these locomotives into the 21st century to haul the Khyber Steam Safari on the rugged Khyber Pass Railway.
The British Engineering Standards Committee (BESC, later renamed to the British Engineering Standards Association), founded in 1901, envisioned standardised locomotive classes for use in British India, to enable more efficient production and maintenance. [2] In the second plan of the scheme in 1907, the HG class, designed for heavy goods trains, was first mentioned. As with the AP and HP classes of passenger locomotives, the HG was offered with three different tenders: the smaller 3000 gallon and 4000 gallon three-axle tenders, and the larger 4500 gallon bogie tender.
In addition, the 1907 BESA report also catalogued two variants: Variant A with 5 ft 1+1⁄2 in (1,562 mm) diameter driving wheels, which was proposed by the Indian Railways Ministry, and Variant B with 4 ft 8+1⁄2 in (1,435 mm) diameter driving wheels, in common with several other locomotives already in use on various railways, including the Bengal Nagpur Railway. Variant A, however, never saw production. [3]
From 1912, the HGS class was introduced, fitted with the Schmidt superheater - the S denotes superheated. The saturated HG locomotives that were later retrofitted with a superheater were given the classification of HGC - the C in the designation stands for converted.
In 1947, after the British Raj was partitioned, 133 HG series locomotives of the North Western Railway ended up in the hands of Pakistan Railways. Indian Railways, who inherited the remainder, retired their HG series locomotives first in the 1980s, though by this point, most of the remaining saturated HG class had been converted to the HGC class.
Pakistan Railways however, despite steam traction being mostly phased out in Pakistan in the 1990s, retained HGS 2216, 2277, and 2306 for use on the Khyber Pass Railway, where two of them worked top and tail on tourist trains to Landi Kotal, until 2006, when the railway suspended operations owing to the damages caused by monsoon rain. [4] [5] At the time, the Khyber Pass Railway was one of the last remaining locations in the world where broad-gauge steam locomotives were still being used on passenger trains. [6]
Two of the Indian HG series locomotives have been preserved:
