37406 The Saltire Society pilots 66019 on the 6M65 18:21 Didcot to Carlisle Enterprise service on 6 July 2006, seen here passing Yarnton. This train has for years been the favoured way of getting surplus locomotives back up north, and 37 / 66 combinations were common at this time. Obviously in this case the driver is an enthusiast and used the 'tractor' as the train engine. Unfortunately, nearly a year later with the same combination, at the same location, I wasn't so lucky!
