Key Points
- The City of Edinburgh Council’s Transport and Environment Committee voted to approve plans prioritising the southern tram route over the northern extension.
- The proposed southern line will run from Princes Street to the Royal Infirmary of Edinburgh and the BioQuarter.
- Plans for the northern route to Granton are on hold following route difficulties and political disagreements over the Roseburn Path.
- Councillors passed the recommendation by a seven-vote majority, with support from SNP, Labour, and Scottish Green members.
- Scottish Conservatives voted against all tram network expansion, while Liberal Democrats sought specific protections for the path.
- Total costs for the wider expansion plan are estimated between £1.7bn and £2.9bn, with funding required from council, Scottish, and UK government sources.

EDINBURGH (Edinburgh Daily) September 10, 2026 — In a significant political decision regarding the capital’s transit infrastructure, local representatives approved recommendations that designate the southern line to the Royal Infirmary of Edinburgh and the BioQuarter as the immediate priority for further development.
As reported by Keiran Fleming of STV News, Edinburgh City Council approved the plans for the £1.7bn southern tram extension during Thursday afternoon’s committee session. The decision was secured after councillors from the SNP, Scottish Labour, and the Scottish Greens joined forces to pass the recommendations by seven votes.
The resolution establishes that council officers will focus technical resources, modeling, and economic analysis on connecting Princes Street across the city centre to major healthcare and life-science hubs in the south-east. Concurrently, the northern line to Granton has been placed on hold.
Why Was the Northern Route to Granton Sidelined?
The decision to pause the northern extension stems from operational challenges, public consultation outcomes, and unresolved political disagreements regarding the proposed corridor.
As reported by The Herald Scotland, the northern expansion toward Granton was sidelined in favor of the southern spur following a vote at the Transport and Environment Committee. As detailed by Josh Pizzuto-Pomaco of The Herald, local political factions remained divided over whether the northern route should utilise the Roseburn Path—a former railway corridor currently used as a popular walking and cycling greenway—or an alternative on-street route via Orchard Brae and Dean Bridge.
According to committee reporting, the lack of a clear, unified consensus on the route, combined with complex engineering demands and localized objections, led officers to recommend prioritizing the south, where high-density transport demand to the hospital complex is already established.
How Did Political Parties and Public Figures Respond to the Decision?
The vote highlighted distinct divisions within City Chambers regarding infrastructure spending and route selection.
As detailed in official reporting from The City of Edinburgh Council, Transport Convener Stephen Jenkinson stated:
“Whilst we’re prioritising the southern section of the planned expansion, I’m clear that the whole city should ultimately enjoy the many benefits of a truly integrated public transport system. One of the key questions around this project is rightly on funding. To progress not only to the next phase of the business case but potential future construction costs, we need to demonstrate clearly how our plans will positively impact our region and Scotland as a whole.”
As reported by Keiran Fleming of STV News, the Scottish Conservatives voted against the motion, maintaining an absolute opposition to any new tram expansion. Conservative members argued that the overall £1.7bn project remains unfunded and unsupported by local residents in affected communities.
Furthermore, as noted by Phyllis Stephen of The Edinburgh Reporter, Transport Convener Stephen Jenkinson acknowledged that final construction funding could range up to £2.9bn across the wider master plan, requiring multi-agency contributions. Jenkinson observed that capital would likely need to be drawn from “multiple sources – whether it is The Scottish Government, The UK Government or a combination.”
As cited by Michael MacLeod in The Edinburgh Minute, local representatives and Members of Parliament had previously expressed concern that shelving the northern segment risks neglecting residents in northern communities who require improved links to the broader transport grid.
What Is the Timeline and Next Phase for the Southern Line?
With the priority vote finalized, work shifts toward the formal business case framework.
Officers are preparing a comprehensive Strategic Business Case (SBC), which will incorporate data from the wider regional SEStransit study. The completed strategic evaluation is scheduled to return to the council for formal review by late summer.
Current estimates from transport planners indicate that even under favorable approval conditions and secured funding streams, it will take up to a decade before passenger services become operational on the southern extension.
Background of the Edinburgh Tram Development
Edinburgh’s modern tram system opened in May 2014 after years of public debate, construction delays, and significant budget overruns surrounding the initial line from Edinburgh Airport to York Place. That first phase was built following the defeat of a 2005 congestion charge referendum that had originally been intended to fund a multi-line network.
Despite initial political fallout, the network saw substantial progress with the opening of the £207m Newhaven extension in June 2023. The extension ran down Leith Walk to the waterfront and saw passenger numbers double within its first year of operation.
Following the success of the Newhaven line, the City of Edinburgh Council initiated a major public consultation in late 2025 regarding a prospective north-south axis. The consultation presented options linking Granton in the north to the Royal Infirmary and BioQuarter in the south-east. The consultation concluded in November 2025, culminating in the analytical reports that led to Thursday’s decision to divide the project and prioritize the southern leg.
Prediction: How This Development Will Affect Key Groups
The council’s decision to prioritize the southern extension will have distinct impacts on local demographics, transport users, and municipal planning across the capital.
Patients, Healthcare Workers, and Visitors
The decision directly addresses long-standing congestion along the South Bridge and Old Dalkeith Road corridors. Connecting Princes Street directly to the Royal Infirmary of Edinburgh and the expanding Edinburgh BioQuarter life-sciences campus will reduce travel times for thousands of NHS employees, outpatient visitors, and emergency services accessing the capital’s central hospital.
Residents and Active Travel Advocates in Northern Edinburgh
For communities in Granton, Pilton, and Western Harbour, the shelving of the northern line delays anticipated direct light-rail connections to the city centre. However, active travel groups and local walkers using the Roseburn Path will temporarily see the greenway preserved in its current form, avoiding immediate construction disruption or conversion into a shared transit corridor.
Commercial Businesses and Real Estate Developers
The decision provides planning clarity for developers operating along the south-eastern corridor. The confirmed transport link is expected to increase commercial investment and commercial lab-space development around the Edinburgh BioQuarter. Conversely, retail and hospitality businesses along Princes Street and South Bridge will need to prepare for eventual major utility diversions and infrastructure works as civil engineering plans advance.
