As a result of this defeat, in 1879, drivers and firemen from Griffithstown, Pontypool, South Wales, started to organise to form a craft union separate from the ASRS. At the time there were similar moves in parts of England towards founding an enginemen's union. A large number of drivers and firemen met in Birmingham met on 9 December 1879 and resolved to form a National Society of Drivers and Firemen. There was a similar move by Manchester, Sheffield and Lincolnshire Railway drivers and firemen at Sheffield, whom the Pontypool group called " "the first founders of the Society"". The Sheffield branch opened on 7 February 1880 with William Ullyott, one of its leaders, as the first member. Pontypool branch followed on 15 February, led by Charles H. Perry, one of the drivers who had unsuccessfully petitioned the GWR board the previous year. ASLEF officially records Perry as its founder. In the remainder of 1880 ASLEF opened branches at Tondu, Liverpool and Leeds (April), Neath (May), Bradford (June), and Carnforth (July).
