Collett Manor class 4-6-0 7826 Longworth Manor has evidently seen better days. However, I had no knowledge of the location until the gentlemen below kindly helped out back in Fotopic days.
However, David Goddard comes to the rescue: No.7826 is on a Carmarthen to Aberystwyth train which has stopped at Llanpumpsaint station where my grandfather was signalman.
And more from Stephen Davies: Just to confirm the location as the down platform at Llanpumpsaint on the Carmarthen to Aberystwyth line. This section (actually Pencader to Aberystwyth) formed the only built part of the grandiose Manchester and Milford Railway, a fascinating example of Victorian over-confidence and hubris. It was intended to carry American cotton to the mills of Manchester from Milford Haven, which would then rival Liverpool, but the project coincided with the American civil war (route survey 1861, start of hostilities - 1861)! But what a beautiful line.
