COST OF the £600M East London Line Extension could soar if plans now being considered to extend station platforms on the existing line go ahead.
Along with new escalators at Canada Water, Wapping and Rotherhithe underground stations, bigger platforms would be needed for eight car trains, an option being considered by a Strategic Rail Authority (SRA) review of the project which started last month.
The platforms currently only cater for four car underground trains. An SRA spokesman confirmed this week: 'If there was a decision to have eight car trains running through those stations it is likely that there would need to be an extension to those platforms.'
He added: 'Whether that is the case depends on the outcome of the audit we are carrying out.'
Under the scheme, the East London Line will be extended from Shoreditch to Dalston in north east London with a possible link further north to Finsbury Park. The line would also be extended south to connect with Railtrack's Croydon line at New Cross Gate and new track south of Surrey Quays would also join into Railtrack's South London line to Wimbledon.
The SRA audit is expected to be complete in two months. from six to 18 an hour.
