Great Eastern Railway followed by London and North Eastern Railway
The Great Eastern Railway (GER) was a pre-grouping British railway company, whose main line linked London Liverpool Street to Norwich and which had other lines through East Anglia.  The company was grouped into the London and North Eastern Railway in 1923.
Formed in 1862 after the amalgamation of the Eastern Counties Railway and several other smaller railway companies the GER served Cambridge, Chelmsford, Colchester, Great Yarmouth, Ipswich, King's Lynn, Lowestoft, Norwich, Southend-on-Sea (opened by the GER in 1889), and East Anglian seaside resorts such as Hunstanton (whose prosperity was largely a result of the GER's line being built) and Cromer. It also served a suburban area, including Enfield, Chingford, Loughton and Ilford. This suburban network was, in the early 20th century, the busiest steam-hauled commuter system in the world.
The majority of the Great Eastern's locomotives and rolling stock were built at Stratford Works, part of which was on the site of today's Stratford International station and the rest was adjacent to Stratford Regional station. The GER owned 1,200 miles (1,931 km) of line and had a near-monopoly in East Anglia until the opening of the Midland and Great Northern Joint Railway in 1893 although there were a number of minor lines, such as the Mid-Suffolk Light Railway that stayed resolutely independent until after the grouping in 1923.Infrastructure

Engine sheds
The Great Eastern had one of the largest engine sheds in the country at Stratford which in January 1923 had an allocation of 555 locomotives. At the other end of the scale, small engine sheds at the end of country branch lines had perhaps one or two locomotives in their charge. At this time the locomotives were generally allocated to the major shed in the area and the smaller sheds had no actual allocation.Before 1914 the engine sheds were organised into districts, with sheds at: Stratford; Ipswich; Norwich; Cambridge; Peterborough; King's Lynn; and Doncaster. In 1914 this was reduced to five with King's Lynn and Doncaster being abolished. By 1915 they were organised onto four districts (primary sheds in parenthesis): Southern (Stratford); Eastern (Ipswich); Northern (Norwich); and Western (Cambridge/Peterborough).
The Great Eastern did not see the maintenance of engine sheds as one of its top priorities. Many original structures it inherited from constituent railways struggled on in various states of disrepair, not only through Great Eastern days, but through its successor company London & North Eastern Railway from 1923 until 1947 and indeed to the end of steam on the Great Eastern in 1959.
Coaling at engine sheds was generally done by hand with the coaling stages constructed of wood. At a busy engine shed such as Stratford, each individual coaler employed on the coaling stage was expected to empty the contents of a 10-long-ton (10 t) coal truck during his shift.
Turntables were generally small – in 1900 the longest was 50 feet (15 m) – enough to turn the later B12 Class 4-6-0 locomotive. By 1932, with the advent of bigger locomotives and the working of other companies' locomotives onto GE territory, turntables had grown, with the major sheds generally having 60-or-65 ft (18-or-20 m) turntables.
In 1922 the GER locomotive allocation across its sheds was: Cambridge - 178; Colchester - 47; Doncaster - 5; Ipswich - 131; King's Lynn - 37; Lincoln (Pyewipe Junction) - 12; Lowestoft - 22; March - 97; Norwich - 119; Parkeston - 20; Peterborough East - 86; Stratford - 555; Wisbech - 7; and Yarmouth - 20. Each main shed had a number of sub-sheds and locomotives would work from these sheds for significant periods. For instance it is estimated that some 150 engines were outbased from Stratford at any one time.
