The Indian locomotive class XP was a class of experimental Шаблон:Whyte "Pacific" type steam locomotives used on Шаблон:Track gauge broad gauge lines in India.Шаблон:SfnШаблон:Sfn[1]
The two members of the class were built by Vulcan Foundry in Newton-le-Willows, Lancashire, England, to an order placed by the Great Indian Peninsula Railway (GIPR) in 1935.Шаблон:Sfn
Background
The class XP was intended to have the power of the class XC heavy passenger Pacific locomotives, but the operating area of the light axle load class XB Pacifics.[2]
The performance objectives set for the class XP were running mileages of Шаблон:Convert between overhauls, and a monthly average mileage of Шаблон:Convert. Both of these objectives were very ambitious for the time.[2]
Design details
The basis for the class XP design was the boiler and firebox of the XB, with some modification to their details. The wheels and cylinders of the two classes had the same dimensions.[2]
The XP's boiler pressure was higher, and its tractive effort was greater, than those of both the XB and the XC.[2]
Both class XP locomotives were fitted with Caprotti valve gear, and roller bearings on all engine and tender wheels. The class leader's bearings were supplied by Timken, and its class mate's bearings were by Skefco.[2]
In 1946, when the Indian government ordered the 16 class WP prototypes, their design was based on that of the class XP.[2][3]
Service history
The class XP locomotives entered service with the GIPR in 1937, as nos. 3100 and 3101.Шаблон:Sfn[2]
The class leader was named King George, in honour of the then King-Emperor of India, and the other class XP engine was named Queen Elizabeth, after the then Queen-Empress.Шаблон:Sfn
In November 1951, the GIPR was incorporated into the Central Railway zone of the Indian Railways. In the All-India renumbering of 1957, the two class XP locomotives were given the numbers 22599 and 22600, respectively.Шаблон:Sfn[2]
Both locomotives had been withdrawn from service by 1970.[1]
