Quite right Sedayne, nowt wrong with trainspotting as long as you call it gricing!

Actually, the A4 Pacific "Silver Link" which you saw was really 60019 "Bittern" under several coats of aluminium paint (covers a multitude). "Bittern" is now restored at enormous cost and back on the main line after about 30 years. See rather nice phot in the link -
