Windsor Link Railway

The Windsor Link Railway is a proposed new railway in Windsor, Berkshire, connecting the Great Western and South Western franchise areas and potentially linking both to London Heathrow Airport.
George Bathurst originally proposed the scheme in 2009 as part of David Cameron's "Big Society" initiative with the aim of improved rail services to Windsor which is served by two railway stations, and appears as a very narrow gap in the subregion. Originally the cost estimate was £125 million at the most which included contingency. 
Proposed in 2013, the project is promoted by Windsor Link Railway Limited (WLR), led by businessman George Bathurst. The promoter's aim is for the railway to be entirely privately initiated and financed. The enhanced plans' cost was then estimated as £200 million the link would enable direct trains between Clapham Junction, Richmond, Twickenham, Staines-upon-Thames to the east to and from Slough to the north. Further cost would accrue as to roads and buildings.
The initial plan was this short tunnel through central Windsor. A proof-of-concept was supported by a major rail infrastructure company.
Approval process.
In June 2013, the company announced that Network Rail had approved the next phase of development which entailed seeking private investment. Network Rail stated that was wholly misleading; it did as yet not support or reject the scheme.
On 11 December 2013, the Royal Borough of Windsor and Maidenhead (the Borough) received 1,423 signatures in support of the project. This resulted in the project being discussed at full council on 25 February 2014. A unanimous motion was passed in support of the project, noting the petition, encouraging WLR to engage in the planning process and looking forward to further submissions.
In August 2014, WLR announced that it had retained Turner & Townsend to run a competition to select an investment partner. As of August 2019, no investment partner had been identified for the project
In November 2014, a working group of the Borough, recommended support of the proposals in its local plan if the national heritage body could confirm no substantial harm to heritage assets would occur. This was confirmed by the borough's cabinet on 26 February 2015.
The Borough passed a unanimous motion encouraging plans to come forward.
Also, the local neighbourhood plan included the associated regeneration of the Windsor riverside area in its 'vision day'. The "Windsor Observer" reported on 31 July 2015 that plans for a public consultation on the Windsor Link Railway have been delayed. This is to allow the rail link to be considered in the wider context of a "Windsor regeneration project".
In 2016 "BBC News" reported that the company had released a 'master plan' for the Windsor Riverside area.
This has been followed, in 2017, by the company also announcing that it had completed a "GRIP 2"-style feasibility report and submitted it to Network Rail. In response the council has announced that it was interested in the proposals for improving the riverside area and was appointing its own consultants GL Hearn.
In a post on the Thamesweb forum on 13 December 2012, Bathurst stated "no houses in Windsor or Datchet are necessary to be demolished to provide either the new tunnel in Windsor or the road underpass in Datchet" which was changed later on in the planning process impacting a number of houses in Bridgewater Terrace.
There were multiple local concerns to be addressed, including improving and protecting the riverside environment, views, those raised by Cllr Colin Rayner on technical challenges and disruption during construction. The local concerns include the fact that the link railway track and new station complex and roadways, with its additional commercial offices and related facilities, is planned to be constructed on National Trust land. The construction will be funded by building residential properties along much of the riverside area that overlooks ancient Eton College flood meadows.
Proposals for both phases of the project were submitted to the government on 31 July 2018.
It was rejected by the government in December 2018.
However, in February 2019, two months after being rejected, a letter was sent to the promoters from the Department for Transport stating they had reassessed the case for Phase 1 of the scheme (Slough-Staines via a new station at Windsor Royal) and stated this could have big benefits. This section of the project could be running in five years. This letter has not been publicly shared or published to verify the claims of the promoter of the scheme.
In March 2019, an independent political party set out its policies in a document called "the BOROUGH first" where it said that it will oppose the Windsor link railway and "For many years Windsor has endured the threat of the Windsor Link Railway" which were clear statements against the project 
Route.
Phase 1.
Phase 1 of the scheme would run from Slough to Staines, via Chalvey, Windsor, Datchet, Wraysbury and Sunnymeads. A new all-in-one station in the Windsor Goswells would replace the existing two nearby stations (Riverside and Central).
Phase 2.
Phase 2 of the project involves linking to Heathrow Airport. As the Heathrow Airtrack scheme has been dropped by Heathrow Airport Holdings, the proponents say a much cheaper method of connecting Heathrow to the north west, west and south would be via a bridge over the M25. This would also have benefits for the proposed intermodal freight depot at Colnbrook.
Possible links.
Eventually it was hoped to spur reconnecting the Great Western railway to Bedford via High Wycombe, Aylesbury and Bletchley, by reopening the link from Bourne End station (achieveable by extending the Bourne End branch line a few miles). Other direct services to Heathrow would be enabled from Oxford and from Reading (and the rest of the Great Western routes).
To the south, alternating services from Basingstoke could go to Heathrow and Slough via Frimley (via a re-opened chord), Camberley, Ascot and Virginia Water. This would give most of Hampshire's railway towns a direct connection to Heathrow as well as possibly Dorset's south coast.
By contrast only enabling Heathrow to be directly accessed from London Paddington or London's Piccadilly line and minor stop Hayes & Harlington fetters rail competition and makes for long rail journey times.
"Railnews" sees any such link as a step towards a railway round most of London and notes south-central England's East West Rail (Varsity Line) gives another sector renewed connectivity.
Planning process.
WLR announced in the presentation to the Windsor Neighbourhood Plan, on 16 September 2014, its expected planning process, as follows:
Despite the fact that 9 years have passed since the original idea was proposed no planning application has been made, and the plans have been rejected by the Government and a local meeting held in December 2018 showed significant opposition to the plans
Background.
The project is promoted by the Windsor Link Railway Limited, led by businessman George Bathurst. When initially proposed, one resident described the proposal as a "fantasy". Some local politicians have supported the proposal: Councillor Mohammed Rasib, for Chalvey ward and leader of the opposition Conservative group, expressed strong support. Fiona Mactaggart (Member of Parliament for Slough, 1997–2017) said, "Any proposal to bring better rail links is welcomed, although this plan looks a long way from being realised."
"Ministers welcome the proposals for the Windsor Link Railway and look forward to further work on the business case to confirm whether the scheme is viable."
Chris Grayling, Secretary of State for Transport, had called for 'new ways of working, new ways of funding improvements'.
The Hansford Review, published on 31 July 2017, included the Windsor Link Railway as a case study and called for funding for 'market led schemes' and for pathfinder projects to progress.
In November 2017, the scheme was featured in the "Spectator". Charles Moore wrote, 
Windsor has always had two stations — Central and Riverside — a fact which causes multiple inconveniences. Considering that it is the most visited tourist site outside London, it is absurdly badly connected… [the] Windsor Link Railway scheme would create a single Windsor station (putting the historic buildings of the old ones to other uses). Its first phase would link the Great Western region with the South Western, going from Slough, via Windsor, into Waterloo.
The scheme was also featured in "The Daily Telegraph" on 7 December 2017 'More privatisation could be the best way to save the rail industry'.
In December 2017, the government announced its Strategic Vision for Rail, calling for more private investment in the rail as a way of opening more lines.
"New Civil Engineer" on 7 December 2018 reported that "The Department for Transport (DfT) told Bathurst that it did not think that the scheme’s expected fare revenue matched the capital cost of building the line".
In February 2019, "New Civil Engineer" reported that the DfT had changed its position and demurred on whether it had carried out an economic assessment. The DfT confirmed the scheme proposed had been rejected, quoting "Government’s call for ideas for privately funded railways will hit the buffers because acceptance criteria keep changing, the boss of the rejected Windsor Link Railway (WLR) scheme has claimed".
That same month the "Windsor Observer" reported on a letter to the proponent that had given the scheme a 'surprise boost'. The letter, balanced with risks, said the scheme "'creates the potential for town development by removing the rail corridor from the surface', adding that 'this could generate significant local benefit'".
