FGW's 158852 passes through the Oldfield Park area west of
Bath working the 08.30 Cardiff Central to Portsmouth Harbour service. In my youth when cutting my trainspotting teeth in this area trains such as this were composed of a rake of Mk. 1 stock with a BG marshalled somewhere in the consist topped off with a Class 31 or a 33 hauling. Is a three-car DMU a suitable modern-day replacement; I will leave you to decide!
