A timetable and funding plan for the long-delayed Croxley Rail Link proposal has been drafted.
Hertfordshire County Council has announced it hopes to have the £26million project complete by January 2014.
The recently published East of England Regional Authority's funding advice document suggests a £119.5million government grant for the project. London Underground is set to contribute an additional £18.5million.
The East of England Regional Authority indicated that the project would be delivered around 2017 but Hertfordshire County Council says it hopes to bring this date forward.
Public consultations are planned for this summer with a Transport and Works application set to be submitted in May next year. A public inquiry is proposed for February 2011.
The rail project would link the Metropolitan Line on the London Underground with Watford Junction rail station with new stations being opened in Ascot Road and near the proposed Watford Health Campus and Vicarage Road Stadium.
