Every weekday morning a Great Western Railway four-coach 'Castle' class High Speed Train works a service from Gloucester to Penzance. Today it wasn't available so two-car 'Turbo' DMU 165133 has been pressed into service. It is seen at Exeter St Davids and continued to Plymouth where passengers were transferred to a modern five-car InterCity Express Train for the remainder of their journey.
