Question: When did the railroad that featured the Victorian Railways H class locomotive receive its current name?
Context: The Victorian Railways F class locomotives were built in 1874 (the pattern engine), 1876–77 and 1879–80 by Beyer Peacock and the Phoenix Foundry in Ballarat as 2-4-0 tender locomotives.  They were normally used on passenger trains.  In 1911 the Victorian Railways decided to convert seven of them into "motor" locomotives.  These became 2-4-2 tanks.  They kept their numbers 172–184 (evens only).  The unrebuilt tender engines were taken off register between 1916 and 1922.  The "motors" were taken off register between 1920 and 1929.  Fortunately, one of the class, number 176, survived after being sold to HV Mackay Sunshine Harvester works in 1920, where it stayed there shunting until 1961.  It was then donated to the ARHS in Williamstown and is now the oldest surviving Victorian Railway locomotive, being built in 1880. The Overland is an Australian passenger train service between Melbourne and Adelaide.  It first ran in 1887 as the "Adelaide Express", but South Australians have always referred to the train as the "Melbourne Express".  It was given its current name in 1926.  Now operated by private company Great Southern Rail, the train completes two return trips a week covering 828 kilometres between the state capitals.  Originally an overnight train, it now operates during the day. The Victorian Railways operated in the Australian state of Victoria from 1859 to 1983.  The first railways in Victoria were private companies, but when these companies failed or defaulted, the Victorian Railways was established to take over their operations.  Most of the lines operated by the Victorian Railways were of .  However, the railways also operated up to five narrow gauge lines between 1898 and 1962, and a line between Albury and Melbourne from 1961. The Victorian Railways X class was a mainline goods locomotive of the 2-8-2 'Mikado' type operated by the Victorian Railways (VR) between 1929 and 1960.  They were the most powerful goods locomotive on the VR, aside from the single H class, H220, which was confined to the North East line, until the advent of diesel-electric traction, and operated over the key Bendigo, Wodonga, and Gippsland mainlines. The Palestine Railways H class was a type of standard gauge mixed traffic steam locomotive on the Palestine Military Railway and its civilian successors Palestine Railways and Israel Railways.  The PMR introduced the class in 1919 and Israel Railways withdrew the last ones in 1960. The NZR H class locomotive was a unique class of locomotive used by the New Zealand Railways Department on the famous Rimutaka Incline, the 3 mi section of 1 in 15 (6.67 %) gradient between Cross Creek and Summit, over the Rimutaka Ranges.  The locomotives worked on the Fell mountain railway system and had four horizontal driving wheels between the frames, gripping a centre rail and providing the extra adhesion needed for the climb.  The outside engines drove the rear pair of coupled wheels of 32 in diameter, and the inside cylinders four spring-loaded grip wheels of 22 in diameter.  On the descent, powerful hand-brakes bore against the centre rail, and brake vans with similar braking gear were interspersed at intervals in the train.  The locomotives were never required to run at speeds higher than 15 mph , and their usual operating speed was between 4 and ascending the incline, about 10 mph descending. The Victorian Railways S class was a class of 4-6-2 express passenger steam locomotive operated by the Victorian Railways (VR) in Australia between 1928 and 1954.  Built when the VR was at its zenith and assigned to haul the broad gauge-leg of its Melbourne to Sydney interstate express passenger services, the S class remained the VR's most prestigious locomotive class until the advent of diesel electric locomotives in the early 1950s. The Victorian Railways J class was a branch line steam locomotive operated by the Victorian Railways (VR) between 1954 and 1972.  A development of the successful Victorian Railways K class 2-8-0, it was the last new class of steam locomotive introduced on the VR.  Introduced almost concurrently with the diesel-electric locomotives that ultimately superseded them, these locomotives were only in service for a relatively short time. The DC class was a class of diesel locomotives in New Zealand and Tasmania.  Originally built by General Motors Canada and Clyde Engineering between 1955 and 1967 as New Zealand Government Railways DA class locomotive.  Eighty-five DAs were rebuilt as the DC class locomotive. The Victorian Railways H class was an express passenger steam locomotive operated by the Victorian Railways from 1941 to 1958.  Intended to eliminate the use of double heading A2 class locomotives on "The Overland" services on the steeply graded Western line to Adelaide, wartime restrictions led to only one locomotive being built.  Nicknamed "Heavy Harry", H220 was the largest locomotive ever built in Australia and the largest non-articulated steam locomotive to run on Australian railways.
