37603 leads the Pathfinder Tours 1Z87 09:45 Euston to Folkestone Harbour 'Atomic Harbour Master' railtour down the steeply graded Folkestone Harbour branch on 20 October 2007. It is just about to pass over the well used footpath crossing between the Tram Road and Dudley Road. As can be seen from the rusty rails, only one line is used, and the third rail supply was turned off years ago. A cautious descent of this 1 in 30 gradient is required, as the branch ends at the Harbour Station, after a sharp bend, so brake failure is not to be contemplated!
