66004 passes Baulking on 23 April 2015 with the 6C48 13:30 Appleford to Whatley Quarry Mendip Rail stone empties. Hard to believe that at nearly 17 years old, this loco has now lasted longer in traffic than the venerable Class 52 'Westerns', which were the principal motive power on this route in the late 1960s and early 1970s.
