Powlesland and Mason (railway shunting contractors)

Powlesland and Mason were a company that provided steam locomotives and crews for shunting within Swansea Docks.

Latterly, some P&M locomotives were based at locomotive sheds away from the immediate vicinity of Swansea docks,[2] including Danygraig shed, to the east of Swansea, which was located to the west of Jersey Marine railway station.

[3] Powlesland and Mason utilised a fleet of nine 0-4-0ST saddle tank shunting locomotives on their railway duties within Swansea docks.

The oldest, P&M No.7, was a former Raven Class broad gauge locomotive constructed for the South Devon Railway Company in 1874, and was sold by the GWR to P&M in 1906.

[1] Four of the locomotives survived to be taken into ownership of British Railways Western Region in 1948 and the last to be withdrawn from service was Peckett-built BR No.
