The Lancashire, Cheshire and North Wales Colliery Enginemen's, Boilermen's and Brakesmen's Federation was a trade union representing engine operators and related workers at coal mines in parts of England and Wales.
This was organised by Thomas Watson, who became the general secretary of the new union.
The union affiliated to the National Federation of Colliery Enginemen and Boilermen, and also to the Trades Union Congress (TUC), with Watson serving a term on the Parliamentary Committee of the TUC.
Watson died in 1921, and was replaced by William Forshaw, who served a term on the General Council of the TUC.
In both areas, former members of the union were placed in their own branch, although over time, some chose instead to join the area's branch for their pit.
