    The Great Western Railway (GWR) 4900 Class or Hall Class is a class of 4-6-0 mixed traffic steam locomotives designed by Charles Collett. A total of 259 were built, numbered 4900–4999, 5900–5999 and 6900–6958. The LMS Stanier Class 5 4-6-0 and LNER Thompson Class B1 both drew heavily on design features of the Hall Class. After nationalisation in 1948, British Railways gave them the power classification 5MT
    The prototype of the new class was rebuilt in 1924 and the cylinders were realigned in relation to the driving axle and a more modern 'Castle'-type cab was fitted. Saint Martin emerged from Swindon in 1924 and embarked on three years of trials. During this period Collett introduced other modifications such a changing the pitch of the taper boiler and adding outside steam pipes.
    After extensive trials during 1925-1927, Collett was satisfied with the performance of his prototype, subject to minor amendments and placed an order for eighty more with Swindon works (Lot 254) in 1928. The prototype was renumbered 4900 in December 1928 and the new locomotives were numbered 4901-80 and appeared at regular intervals until February 1930. They were named after English and Welsh country houses with 'Hall' in their titles and so became known as the 'Hall Class'.
    They differed little from the prototype; the bogie wheel diameter had been reduced by two inches from 3 ft 2 in (0.965 m) to 3 ft 0 in (0.914 m) and the valve setting amended to give an increased travel of 7.5 in (191 mm). The overall weight of the locomotive had increased by 2 long tons 10 cwt (5,600 lb or 2.5 t) to 75 long tons 0 cwt (168,000 lb or 76.2 t) but a tractive effort of 27,275 lbf (121.33 kN) compared favourably with the 24,935 lbf (110.92 kN) of the 'Saint'. The original locomotives were built with Churchward 3,500 imp gal (16,000 l; 4,200 US gal) tenders but after 4958 Collett's larger 4,000 imp gal (18,000 l; 4,800 US gal) types became standard although a few later locomotives were fitted with smaller tenders if these were available as they entered service.
    The first fourteen examples were despatched to the arduous proving grounds of the Cornish main line. They were so successful here and elsewhere on the GWR system that by the time the first production batch had been completed a further twenty were on order (Lot 268, 4981-99 and 5900). Further orders followed throughout the 1930s and early 1940s. By 1935, 150 were in service and the 259th and last Hall, No. 6958 Oxburgh Hall, was delivered in 1943. Thereafter further deliveries were of the '6959 Modified Hall' class
    All but one of the original Collett Halls entered British Railways service in 1948, the exception being No. 4911 Bowden Hall. Official withdrawals began in 1959 with the prototype Saint Martin. Its accumulated mileage, both in its original form and rebuilt form, was a remarkable 2,092,500 miles. Further withdrawals of the production series took place during the 1960s and the class was extinct by 1965.
