Croxley Rail Link
The Croxley Rail Link, or the Metropolitan Line Extension, was a proposed railway engineering project in the Watford and Three Rivers districts of Hertfordshire, England, that would have connected the London Overground and the London Underground's Metropolitan line at. The Metropolitan line's terminus at Watford Underground station would have been closed and the line diverted and extended from Croxley to Watford Junction via a reopened section of closed line. The main proponent of the scheme was Hertfordshire County Council but it failed to win the support of Transport for London which owns the Watford branch. The engineering works would have consisted of the realignment of the disused Watford and Rickmansworth Railway's line between and, with the construction of a viaduct over the Grand Union Canal, River Gade and A412 road and two new stations before branching into the London Overground line near and continuing to.
The proposed route was featured in a Transport for London network map for 2016 and the Transport for London Indicative 2025 Transport Map on which Watford tube station does not appear. Were the link to be built, direct services between Watford Junction and would be possible but were not included in the business case for the scheme.
The project was approved by the Government on 14 December 2011 and vegetation clearance started during 2013. The project received final Government approval through an Order of the Transport and Works Act on 24 July 2013 and was signed off and formally given the green light by the government on 17 March 2015 when it was confirmed that Transport for London would be responsible. Work on the extension stopped in 2016 due to anticipated cost overruns and an unresolved dispute over funding.
History
The present-day London Underground Watford Met station is situated close to Cassiobury Park and somewhat peripheral to the town centre. Watford Urban District Council objected to the proposal to drive a railway across the park, resulting in the terminus of the Watford branch being a mile from the High Street.Also in the area was the single-track Watford and Rickmansworth Railway that opened in 1862 between and. British Rail withdrew passenger services from the Rickmansworth branch in 1952 and ran a skeleton service on the Croxley Green branch until 1996.
Over the years, various schemes were considered to extend the Metropolitan line into the centre of Watford, including an abandoned plan in 1927 to open a Metropolitan Railway station on the High Street,. In 1948, the London Transport Executive, part of the British Transport Commission, considered a proposal to link the Metropolitan line to the BR Croxley Green branch line. A similar proposal was put forward by London Regional Transport around 1994. Because the line lay entirely within Hertfordshire, it was championed by the county council who lobbied for funding from LRT and the Department for Transport for 16 years.
Funding
In 2005 Transport for London tentatively committed to providing up to £18m of the estimated cost of £65m, predicting that the link would be operational by 2010. Difficulties arose in securing the remaining funding from the Department for Transport and a revised project submission, under new guidelines, was prepared, with a view to obtaining Programme Entry status. A business case was submitted to the DfT in February 2008, with revised costs of £95m. The proposal was rejected in March on the basis that no guarantee of financial backing had been received from TfL. In July 2008 the East of England Regional Assembly declared the scheme a "priority" and agreed to contribute £119.5m towards the estimated cost, now £150m. Hertfordshire County Council agreed to allocate £25.8m which it hoped to recover through ticket sales and other London Underground revenue. It was predicted that the link could be operational within seven years.A revised business case was produced in autumn 2009 and the costs and scope reviewed. Following the Cameron–Clegg coalition's Comprehensive Spending Review the project was placed in the pre-qualification pool and a further submission made to the Department for Transport in January 2011. In February 2011 the Department for Transport placed the project into a qualification pool of works that would be subjected to further assessments in order to bid for funding. A Best and Final Funding Bid was submitted to the Department in September 2011. On 14 December 2011, the Department for Transport agreed to fund £76.2m of the £115.9m cost, with the remainder from the local authorities and third parties.
In December 2014, Hertfordshire County Council announced that the projected cost of the scheme would rise to £230 million. It was also reported that London Underground could take over construction of the link from Network Rail. According to TfL, HCC had significantly underestimated the costs and the project was faced with "significant project slippage and cost escalation", and for this reason an agreement was reached with the DfT and HCC whereby London Underground would assume full responsibility for the project, subject to a suitable funding package. Hertfordshire County Council would now contribute £230m, £34m would be provided by central government, and LU was to contribute £16m. The opening date was put back to 2020.
On 25 January 2017, the Watford Observer newspaper confirmed that work which had been ongoing since 2014 had stopped as there was an ongoing funding issue; Transport for London were stating that more than £50m additional funding was required. A Freedom of Information request revealed that £130m of the £284m funding had already been spent, but the only works that had actually been delivered were some utility diversions and route clearance.
In September 2017, Sadiq Khan, the Mayor of London, gave more clarity to the issue, relieving Transport for London of any obligation imposed on it by the previous Mayor, Boris Johnson, to fund a cost overrun. It was noted that at the budgeted cost of £284.4m, the cost-benefit ratio of the project was only 0.4, so funding a cost overrun now estimated at £73.4m on top of the £49.2m Transport for London were already contributing, would not give value for money. It stated that Transport for London's sunk expenditure on the project was £71.2m, of which £15.5m was for buying an additional train, which has been delivered and put into service.
In 2018, the government offered Transport for London the £73.4m additional funding it was apparently asking for, taking total funding available to £357.8m, subject to Transport for London accepting cost overrun risk again. This arrangement was turned down by the Mayor. The parties were later reported to be examining cheaper alternative schemes such as a rapid bus transit scheme and light rail.
Proposed route and stations
A key part of the project was the construction of the "missing link", a short line of track that would have connected the existing Metropolitan line to the former British Rail Croxley Green branch line at their closest point; this would have been achieved by a new junction near Baldwins Lane, about northeast of Croxley station and a viaduct and a bridge to carry the Metropolitan line over the A412 Watford Road dual carriageway and the Grand Union Canal to the former BR line. Double track would have been laid along the disused trackbed, reinstating the line as far as Watford High Street.None of the former BR stations that closed in 1996 would reopen. Two new stations were to be built: Croxley Green station replaced by and a second station,, would have replaced and the football specials halt,. The new stations would have had ticket machines instead of staffed ticket offices.
Stations
The name Ascot Road was initially chosen by consultants for the first of the two new stations; however, many local people and councillors felt that this name would not reflect the identity of the area. Transport planners also expressed concern that the new Tube station may be too easily confused with Ascot Station in Berkshire. The name was suggested due to historical connections with the area and because of a bridge over the Grand Union Canal, and after some consultation, it was confirmed in August 2013 that the Cassiobridge name would be used instead.The planned Watford Hospital station had its name changed to Watford Vicarage Road because it was felt that the association with Vicarage Road football stadium would ensure wider recognition outside the local area.
Watford Met station
Transport for London had stated that passenger services on the Metropolitan line from Croxley to Watford would cease when the Croxley Rail Link opened; Watford Met station would close, although the short branch might remain in operation as a reversing siding. Following closure, the nearest new station to Watford Met would have been, about away. The plan to close the station had been the subject of some local opposition, and campaigners argued for a reduced shuttle service to be operated on the branch.Ending services on part of the line and closing a station require a formal closure process involving London TravelWatch. The London TravelWatch Board set up a Watford Station Closure Panel; the panel held a public meeting in Watford on 14 June 2012 to present arguments to TfL against the station closure.
Amersham link
There was a further suggestion that with use of the existing, but seldom-used, Metropolitan line chord which allows trains to run from Watford towards via in conjunction with this rail link, direct services between Watford Junction and Amersham might have been possible some time in the future. London Regional Transport's adapted internal planning Tube map of 1994 illustrated this idea.The proposal was included in a Greengauge 21 report "Capturing the Benefits of HS2 on Existing Lines"." The report proposed that High Speed Two would increase capacity on the West Coast Mainline, increasing the benefits of an "Amersham Link" to the Croxley Link. These benefits would be further increased by the planned substantial increase in service to Watford Junction and London Euston. It was claimed that this could support a new service from Aylesbury and other London to Aylesbury Line destinations to Watford Junction."
