Ambitious plans for a third attempt at a new public transport system for Leeds have been dragged into the General Election campaign.
The Conservatives have claimed they would back the plan if they secure a majority government.
In a statement they said would put £4.2bn into boosting public transport across the country which could be used to fund public transport projects, including "a new metro or light rail" service in West Yorkshire.
The Tory statement is the first hint that another Supertram style system would be favoured.
Officials at West Yorkshire Combined Authority had not yet committed to what mode of transport was being considered.
As first revealed by LeedsLive last year, the new mass transit system has three lines, one of which goes into Pudsey and Dewsbury, both key Tory targets in the upcoming general election.
Leeds remains the largest metropolitan area in Europe without an urban transit system and earlier this year Prime Minister Boris Johnson described this situation as "madness".
The Conservative statement said: "A new, devolved and long-term Local Public Transport Fund will give eight combined authority areas, including West Yorkshire, the control and certainty of funding they need to invest.
"While local leaders will have the final say over how to spend it, projects it is expected to help fund include a new metro or light rail, including to Dewsbury, Pudsey and the Spen Valley."
Elsewhere, Liberal Democrat deputy leader Sir Ed Davey visited Leeds last month, promising that the party would build Leeds its mass transit system if elected into power.
Labour meanwhile want to reinstate 3,000 bus routes and will deliver rail electrification across the country while slashing rail fares by a third.
Under WYCA's plans, line one would then serve Holbeck, Armley, Bramley and Pudsey before heading into Bradford and North Kirklees, ending at Dewsbury.
Line two shows routes serving Leeds Dock, Temple Green, a new park and ride at Tingley, Woodlesford and Castleford.
Line three appears to go through Leeds central station to the arena, St James' Hospital, Harehills, Seacroft and on to Thorpe Park.
Plans for a Leeds Supertram emerged in 1993 but were ditched in 2005 when the Government withdrew the promised funding.
A second scheme for the NGT (New Generation Transport) trolley buses was unveiled in 2006 but was cancelled ten years later.
It is thought more than £72m was spent on the failed proposals.
