History

In 1888, Holden experimented by removing the side rods of T19 No. 721 to form a 2-2-2. [1] In 1889 the first of a new class appeared: initially No. 740 (later 789 and 780) which had been built on a 'Locomotive and Machinery' account. This was followed by two batches of ten on the more normal 'Letter' account. [2] in 1893. They were built with 18 in × 24 in (457 mm × 610 mm) [3] inside cylinders powered by a 140 lbf/in2 (965 kPa) boiler. They were later rebuilt with 18 in × 25 in (457 mm × 635 mm) and 160 lbf/in2 (1,103 kPa) boilers. [2]

One of their main spheres was on the Joint Line working expresses to York. In 1896 the class inaugurated the epic making non-stop run to North Walsham using oil-firing. Rous-Martin [4] found that the singles climbed Brentwood Bank more rapidly than the 2-4-0s. See also Ahrons (1951).

Nine locomotives were withdrawn between 1901 and 1903. The surviving eight locomotives in the 770-series were transferred to the duplicate list in July 1904, and had their number prefixed with a "0". The remaining fourteen were withdrawn between 1904 and 1907. [5]

<span class="mw-page-title-main">GER Class G58</span>

The GER Class G58 is a class of 0-6-0 steam tender locomotives designed by James Holden for the Great Eastern Railway in England. The class consisted partly of new locomotives built from 1905 to 1911 and partly of rebuilds of the earlier GER Class F48 built from 1900 to 1903. The rebuilding started under GER auspices from 1921 and was continued by the London and North Eastern Railway (LNER) after grouping in 1923.

<span class="mw-page-title-main">GER Class T19</span>

The GER Class T19 was a class of 2-4-0 steam tender locomotives designed by James Holden for the Great Eastern Railway. Some were later rebuilt with larger boilers while others were rebuilt with both larger boilers and a 4-4-0 wheel arrangement. Unusually, both the 2-4-0 and 4-4-0 rebuilds were classified as GER Class T19 Rebuilt. All the 2-4-0s had been withdrawn by 1920 so only the 4-4-0s passed to the London and North Eastern Railway in 1923 and these became the LNER Class D13.

At the 1923 grouping they all passed to the London and North Eastern Railway, who classified them E4. Eighteen survived into British Railways ownership in 1948, and the last was withdrawn in 1959, making them the last 2-4-0 tender locomotives at work in Britain. Their BR numbers were 62780–62797.
