GWR 42XX class 2-8-0T 4290 at Severn Tunnel Junction shed on April 14, 1957.

Peter Kerslake says "A fine portrait of Newport Ebbw Vale's heavy mineral tank 4290 here at Severn Tunnel Junction in Aprilof 1957, the class having been a development from the 2-8-0 class "2800" tender engines and built to fulfil a need for the increasing volume of South Wales coal, coke and mineral rail traffic in the early 1900's.
Initial plans had been for a design based on a 2-8-2 tank engine and when after the first war such traffic declined a number of the class were rebuilt at Swindon into such 2-8-2 form with extended frames and a larger capacity coal bunker increasing its capacity by two tons to a total of five and a half tons thereby enabling them to work longer distances from Wales."
