On current form it looks neck and neck.
TfL announced this week that it has descoped the proposed four tracking of the North London Line between Caledonian Road and Camden to a two track affair.
The grounds for this was the poor condition of a number of bridges along the route that would have required renewing.
By not four tracking throughout the project saves £40 million.
However, the removal of two platform faces at Camden will prevent the delivery of an 8 train-per-hour service throughout the day.By not four tracking throughout the project saves £40 million.
Which may disappoint the cash strapped ODA who are reported to have put £100m into the scheme to help move people to and from the Olympic site.
Poor BoJo. What looked like a £40m saving may soon turn into a very large bill from the ODA.
