37377 & 37098 round the sharp curve at Roman Bridge on 18 April 1998 with the Hertfordshire Railtours 1T54 14:57 Trawsfyndd to Euston 'Roman Nose' railtour. So sharp is the curve, that 59205 L Keith McNair can clearly be seen on the rear of the train, just passing the diminutive Roman Bridge station. 59205 had earlier led the train down the Trawsfyndd branch.
