Very unusual motive power on the Great Western Mainline at Circourt Bridge, Denchworth, on 5 January 1985. Class 203 1032 & Class 202 1017 head west with the Hertfordshire Railtours 1Z27 07:20 Watford Junction to Maerdy 'Cymru DEMU' railtour. A mad panic set in during the mid 1980s to take these narrow bodied Hastings units to far flung places that they had never visited before, prior to their withdrawal in 1986 with the completion of the Hastings Line electrification.
