of the older E&M engines, often much rebuilt. The famous Beyer-Peacock engines survived in this way from the early 1880s to the mid-1930s. The best contemporary designs were acquired by the Joint in the 1893 – 1901 period, but as there were no more modern engines forthcoming, the light 0-6-0s and 4-4-0s provided much of the motive power on the line until 1936. From then on the LNER tried various designs on the line, not necessarily bigger or even more recent than the Joint's own engines, but as the M&GN's engines were scrapped, newer engines such as the K2 2-6-0s and B12 4-6-0s became common. The ex-GER D16 "Claud Hamilton" 4-4-0s provided the locomotive backbone of this later period. From the 1950s, Ivatt 4MTs became the dominant motive power on the system, which achieved a higher degree of standardisation than any other part of British Railways—more than 50 of these "mucky ducks" were allocated here. But there were other types still in use, and among them the line saw Ivatt 2MTs and occasional Standard 4MT and LNER B1 and B17 types. British Railways' Eastern Region was an early adopter of diesel motive power and the M&GN lines were used by Brush Type 2 locomotives and several early DMU types including Class 101 and Class 105s. A fleet of the latter was commissioned in the mid-1950s to take over all the long-distance locomotive-hauled passenger services, but the line's closure in 1959 saw them re-allocated (especially to the Great Northern suburban commuter workings out of King's Cross, for which they were particularly unsuitable). One M&GN boiler from a Hudswell Clarke 4-4-0T survives, it is hoped this will be rebuilt as a static exhibit. Badge and livery The M&GN device consists of images derived from the coats of arms of the four principal cities and towns it served: (clockwise from top left) Peterborough, Norwich, Great Yarmouth and King's Lynn. For much of the company's life the locomotives were painted a light golden brown, often referred to by paintshop staff as "autumn leaf" or "golden ochre". From 1922 the goods engines were painted dark brown, followed by the rest of the locomotives in 1929. The LNER painted the survivors black. Most of the carriages were ex-GNR and were varnished teak, but some of the older stock and rebuilds were painted and grained to look like teak. Wagon stock was generally brown oxide, the same
