City of Edinburgh Council Approves Strategic Business Case for £1.7 Billion South Tram Extension to BioQuarter and Royal Infirmary

A Transformative Mass Transit Link to Scotland's Premier Health Sciences Precinct

EDINBURGH, Scotland — In a monumental statutory milestone for public transport in Scotland's capital, the City of Edinburgh Council’s Transport and Environment Committee has officially voted to approve the Strategic Business Case (SBC) for the new south Edinburgh light rail corridor. The decision firmly prioritizes the £1.7 billion southern tram extension, establishing a high-capacity, zero-emission mass transit spine connecting Edinburgh City Centre directly to the Edinburgh BioQuarter and the Royal Infirmary of Edinburgh (RIE).

Running from Princes Street via Newington and Cameron Toll, the dedicated route will serve more than 15,000 healthcare professionals, medical students, patients, and biomedical researchers every day, relieving extreme automotive congestion along the capital’s arterial southern corridors and slashing travel times to the region's primary trauma center.

Regional Transit Integration and Heavy Rail Feasibility Alignment

The approved Strategic Business Case will now be formally integrated into the broader regional findings of SEStransit, the South East of Scotland regional transit framework. In tandem, municipal transport planners are aligning the tram corridor with ongoing feasibility studies investigating the potential reintroduction of scheduled passenger rail services along the Edinburgh South Suburban Railway (Sub).

On the highway network, the Scottish Government confirmed that site investigations are complete for the £120 million grade-separation of the Sheriffhall Roundabout on the A720 City Bypass under the Edinburgh and South East Scotland City Region Deal, with heavy civil construction scheduled to eliminate one of Scotland's most notorious traffic bottlenecks.

£208 Million Capital Allocation Combats Declared Housing Emergency

The transit investment arrives as City of Edinburgh Council accelerates delivery under its officially declared housing emergency, deploying a £208 million capital development budget for the 2026/27 financial year as part of an overarching £1.3 billion five-year housing plan. The council confirmed it exceeded statutory affordable housing targets by completing or acquiring 1,473 high-quality sustainable homes over the past twelve months.

Massive master-planned residential regeneration is progressing rapidly across key urban growth zones, headlined by the flagship Granton Waterfront development along the Firth of Forth—which will deliver 3,500 net-zero homes, creative studios, and coastal parklands—alongside major transit-oriented mixed-use communities in West Edinburgh.

Delivering a Resilient, Net-Zero Capital City

City leaders emphasized that linking world-class clinical research institutions and teaching hospitals with modern light rail, while simultaneously unlocking brownfield waterfront land for energy-efficient council housing, provides an integrated model for sustainable urban growth. By diverting millions of private car trips each year onto electric trams, Edinburgh is safeguarding its UNESCO World Heritage architecture while making measurable strides toward becoming a carbon-neutral capital.
