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 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.
