Edinburgh City Council set out plans for nearly £900M worth of transport investment last Friday when it published its Local Transport Strategy.
Top of the council's wish list are North and West Edinburgh Tram, costing £375M, and South Edinburgh Tram, costing £177M.
But the council warned that realisation of these projects hangs on the provision of funding from the new regional transport partnerships.
'There is no long-term guarantee that funding will be available for local schemes, ' said a council spokeswoman.
'Executive funding sources that local authorities used to be able to bid for, such as the Public Transport Fund, are no longer available.
'Most Scottish Executive funds will be channelled through the local transport network partnership, which in south east Scotland is Sestran.' Sestran has already approved extension of Edinburgh's bus tracking system and bus priority measures at a cost of £14M, and cycle route improvements costing £18M.
Edinburgh Council also wants to push ahead with additional rail improvements costing £4M, rapid transit on the City Bypass costing £9M, additional maintenance costing £50M, and 20mph zones costing £21M.
Proposals to upgrade Waverley Station and build the Edinburgh Airport rail link are waiting for funding from the Scottish Executive.
