155310 passes Sherrington on a bitterly cold 15 January 1991 with the 2O13 11:29 Cardiff Central to Portsmouth Harbour Regional Railways service. This picture is now just as historic as the pictures of Class 33s working these trains that I took on this route just a few years before. The reign of Class 155s on this line was to be very brief, and in fact this unit would not see out the year as a two car set, being converted into Class 153 single units 153310 & 153360 , which both re-entered traffic in November 1991.
