The two preserved 421cig units make the line a popluar destination for rail-fans. Unit 1497 "Freshwater" was painted in British Rail White and Blue while 1498 "Farringford" was painted in BR Green. The units were given names of places on the Isle of Wight as they only ran on this line. Until 22 May 22 2010 they were the only EMU slamdoor units still in operation anywhere in Britain.
