37350 passes Compton Beauchamp on 14 August 1992 with what is presumably the late running Didcot Power Station to Cardiff Tidal empty oil tanks. At this time the working timetable showed a long gap between the 6V99 Hamworthy to Cardiff steel at around 18:20 and the 6V29 Furzebrook to Hallen Marsh LPG at around 23:00, so this was something of a surprise.
