National Union of Railwaymen; Associated Society of Locomotive Engineers and Firemen; National Busworkers' Association.

The National Union of Railwaymen (NUR) was formed in 1913 by the amalgamation of the Amalgamated Society of Railway Servants of England, Ireland, Scotland and Wales, the General Railway Workers' Union and the United Pointsmen's and Signalmen's Society. The Amalgamated Society of Railway Servants of England, Ireland, Scotland and Wales was the dominant partner in this amalgamation. In 1953 the National Association of Transport Employees was formed and National Union of Railwaymen members in the Irish Republic and Northern Ireland transferred to that union. In 1990 the National Union of Railwaymen amalgamated with the National Union of Seamen to form the National Union of Rail, Maritime and Transport Workers (RMT).
