47625 City of Truro passes Duffryn on 15 August 1987 with the 1V02 06:20 Crewe to Cardiff Central service. At the time this train was sometimes worked by a Class 37/4, but while the 47 may have been a slight disappointment at the time, a Rail Blue 47 on a short set of vacuum braked Mk1s is a very acceptable substitute!
