A pair of 4-CEP units, with refurbished 1516 leading, head south through Petts Wood in autumn 1989. Headcode 18 is
Charing Cross to Margate via Tonbridge, Ashford, Dover, Deal and Minster. The Minster call means that train would
have had to reverse there after using the south to west curve rather than going direct to Ramsgate via the south to
east chord. Thanks to Paul C for info about the Minster reversal.
