The DfT has launched a consultation about South East London train services and seems to be suggesting that the routes through Lewisham and Deptford might in future only terminate at Cannon Street although very little detail is given. The document says:
"There would be a limit to the improvements that could be made to the timetable without also reducing the number of central London stations served from certain locations at particular times. An example might be for all Metro services on the north Kent (between Dartford and Charlton), Greenwich and Bexleyheath lines to terminate at Cannon Street only.
"We believe that the simplicity of a regular service to a single London terminal throughout the day would benefit both regular and occasional passengers. A simpler service can help deliver a step-change improvement in the punctuality of both Metro and Mainline services. We are aware that losing direct connections to particular central London stations has the potential to inconvenience a number of passengers, by requiring them to change their usual journey patterns."
This obviously has some major issues if you don’t pay for the tube. It could significantly add to journey times travelling from Cannon Street to Victoria and put a lot more pressure on TfL There is aconsultation Sat 1st April 10:00-13:00 Lewisham Glass Mill Leisure Centre.
