On their final day in traffic before being sold to DRS, 37603 & 37601 worked the Pathfinder Tours 'Atomic Harbour Master' railtour from Crewe to Folkestone Harbour on 20 October 2007. They are pictured here passing Great Chart (near Ashford) with the 1Z87 09:45 Euston to Folkestone Harbour section of the tour. Although the day started sunny, and was clear again in the afternoon, around midday there was a lot of cloud in Kent, which meant that many photographers didn't get the pair of 37s in the sun, so I was very lucky with this one. The locos were split at Ashford to work the two branches in top'n'tail mode, and there was no chance of a picture later in the day when they paired up again, as due to late running it was dark!
