GWR Castle No 5082 Swordfish near Denham with the down 'Cambrian Coast Express' in August 1957.

Peter kerslake says "Old Oak Common's 5082 "Swordfish" will work through to Shrewsbury on this down "Cambrian Coast Express" from where, after reversal the train will head into Cambrian territory bound for Aberystwyth and Pwllhelli, both sections headed by a lighter engine and later splitting in two portions after arrival at Machynlleth later in the afternoon.
Renamed in January of 1941 from its previous "Powis Castle" name 5082 was withdrawn from its home at Old Oak Common in July of 1962."
