The Swedish Railway Employees' Union (Swedish: Svenska Järnvägsmannaförbundet, SJMF) was a trade union representing workers in the railway industry in Sweden.
The union was founded on 12 May 1899 by 400 workers on private railways.
In 1906, both the Swedish State Railways Association of Foremen, Labourers and Office Workers and the Association of State Railways Engine Workers joined.
[1][2] In 1920, the Swedish State Railways' Guard Union joined, and in 1922, the SJMF affiliated to the Swedish Trade Union Confederation.
In 1925, the Swedish Guard Employees' Union split away, but it rejoined in 1940.
