Overview
Clyde Metro is a proposed, multi-decade, multi-billion-pound mass transit system for the Glasgow City Region, first identified as a national transport investment priority in Transport Scotland’s Strategic Transport Projects Review 2 (STPR2), published in 2022 (Glasgow City Council). It envisages an integrated network combining existing rail and Glasgow Subway infrastructure with new lines, and is being developed across eight local authorities in the Glasgow City Region (Glasgow City Council). The National Wealth Fund, which has provided advisory support on funding and governance options, describes the project’s potential to connect more than 1.5 million people to employment, education and health services over a roughly 30-year investment horizon (National Wealth Fund).
Leadership and funding
On November 24, 2023, Strathclyde Partnership for Transport (SPT) was designated to lead development of Clyde Metro’s Case for Investment (CFI) — described as the project’s next critical phase, establishing a strategic business case and arrangements for initial delivery. Glasgow City Council leader Susan Aitken called Clyde Metro “the transformational, ambitious and deliverable public transport system that the Glasgow metropolitan region has been waiting for” (Glasgow City Council). On March 5, 2024, the Glasgow City Region approved £12.155 million in City Deal funding — split equally between the Scottish and UK Governments — to accelerate CFI development, with SPT adding a further £2.2 million of its own (Glasgow City Council). No funding beyond this development stage has been secured.
Current status as of September 2026
CFI Stage 1 was completed in March 2025, producing a “case for change,” a vision and objectives, and a set of corridor-based network options for further study (Glasgow City Council). As of SPT’s most recent published board papers, from November 2025, the project was in CFI Stage 2: a Preliminary Options Appraisal of corridor alignment options was under way, an Environmental Impact Assessment consultation with statutory bodies had been completed and was under review, and Equality Impact Assessment scoping had identified accessibility and multi-modal integration as key themes. SPT told its board that public consultation on shortlisted network options was planned for February-March 2026, and that delivery was “on track and on budget,” with the full Case for Investment expected to complete in early 2027 (SPT). Transport Scotland’s most recent national delivery-plan update lists continued Clyde Metro CFI development as one of SPT’s stated priorities for 2026 (Transport Scotland). That same Transport Scotland document separately describes SPT as “aiming to deliver a transformational mass transit system by 2027” — looser wording that sits awkwardly against SPT’s and Glasgow City Council’s own, more precise statements that only the business case, not the built system, is due by that date.
Relationship to the Glasgow Airport rail link
Transport Scotland’s 2022 Clyde Metro proposal subsequently absorbed the long-running, twice-scrapped Glasgow Airport Link as one of many components under evaluation, rather than as a standalone project with its own funding or timeline. As of September 2026, no source read for this profile identifies which specific mode, corridor or phase of the eventual Clyde Metro network an airport connection would occupy.
What this profile does not claim
This profile does not claim that any version of Clyde Metro will be built, since as of its most recent independently verified status the scheme remains in business-case development with no construction funding secured. It does not resolve the discrepancy between Transport Scotland’s 2027 “delivery” language and SPT’s and Glasgow City Council’s more precise account of 2027 as only the Case for Investment’s completion date, and it does not attempt to predict which of the network options under appraisal will ultimately be chosen. It also does not independently verify the National Wealth Fund’s ridership-potential or population-reach figures beyond what that source itself reports.
Timeline
- 2022
- Transport Scotland publishes its Strategic Transport Projects Review 2 (STPR2), which identifies Clyde Metro as a national transport investment priority for the following 20 years.
- 2023-11-24
- Strathclyde Partnership for Transport (SPT) is designated to lead development of the Case for Investment (CFI), described as the project's next critical phase; Glasgow City Council leader Susan Aitken calls Clyde Metro "the transformational, ambitious and deliverable public transport system that the Glasgow metropolitan region has been waiting for."
- 2024-03-05
- Glasgow City Region approves £12.155 million in City Deal funding (split equally between the Scottish and UK Governments) to accelerate the Case for Investment; SPT confirms a further £2.2 million of its own funding for the same work.
- 2025-03
- CFI Stage 1 is completed, establishing a "case for change," a vision and objectives, and a set of corridor-based network options for further assessment.
- 2025-11
- SPT reports to its board that CFI Stage 2 is under way, with a Preliminary Options Appraisal of corridor alignment options, a completed Environmental Impact Assessment consultation with statutory bodies, and Equality Impact Assessment scoping; public consultation on shortlisted network options is planned for February-March 2026, with programme delivery described as "on track and on budget."
- 2026
- Transport Scotland's national delivery-plan update lists continued development of the Clyde Metro Case for Investment as one of SPT's stated 2026 priorities, alongside a separate note that SPT is "aiming to deliver a transformational mass transit system by 2027" — phrasing that appears looser than SPT's and Glasgow City Council's own, more precise statements that only the Case for Investment (not the mass transit system itself) is due to complete by early 2027.
What we could not verify
These claims came up in research and could not be confirmed. They are recorded here rather than published as fact or quietly dropped. If you hold a source that settles one, please tell us.
- Transport Scotland's own 2026 delivery-plan document states SPT is "aiming to deliver a transformational mass transit system by 2027," while SPT's and Glasgow City Council's own, more detailed publications consistently describe 2027 as only the target date for completing the Case for Investment (a business case), after which detailed appraisal, engineering design, funding cases and delivery planning would still need to follow. This profile follows the more precise SPT/Glasgow City Council framing and flags the looser Transport Scotland wording as an unresolved discrepancy rather than silently adopting either version.
- No source read for this profile gives a fixed total cost or construction completion date for Clyde Metro; it is described only in general terms as a "multi-billion-pound" investment spanning up to three decades, and no funding beyond the CFI development stage itself has been secured as of September 2026.
- No source read for this profile specifies which mode, phase, or corridor of the eventual Clyde Metro network the former Glasgow Airport rail link proposal would fall under; as of September 2026 it remains only one of several options under evaluation.
Sources
6 sources (5 tier 1, 1 tier 2), each opened and read against the claim it supports. Every source is independent of the subject; no first-party material is cited. See the source policy.
Glasgow City Council's own published announcements (glasgow.gov.uk, local government records, tier1) were fetched and read in full for the STPR2 origin, SPT's November 2023 designation, the March 2024 City Deal funding decision, and the CFI's stage-by-stage timeline. SPT's own committee papers (a public body's committee agenda and report, tier1) were fetched and read in full for the most current (November 2025) status of CFI Stage 2. Transport Scotland's national delivery-plan publication (tier1) was fetched and read in full for Clyde Metro's place among SPT's stated 2026 priorities. The National Wealth Fund's published case study on its advisory role (tier2) was fetched and read in full for corroborating scale and scope figures. Wikipedia's article on Clyde Metro was checked purely as a lead index before any of the above were independently fetched, and is not cited.
- Clyde Metro Supports: Clyde Metro's origin in Transport Scotland's 2022 STPR2, the involvement of eight local authorities, the CFI Stage 1 (complete March 2025) and Stage 2 (under way) breakdown, the early-2027 target for CFI completion, and the £12.155 million City Deal funding split.
- Clyde Metro Development Takes Major Step Forward Supports: SPT's November 24, 2023 designation to lead the Case for Investment, the two-year CFI development timeline beginning in 2024, and Cllr Susan Aitken's quote.
- City Deal funding to advance Clyde Metro development Supports: The £12.155 million City Deal funding approval, its 50/50 Scottish/UK Government split, and SPT's additional £2.2 million contribution.
- Clyde Metro: Case for Investment - progress update Supports: The November 2025 status of CFI Stage 2, including the Preliminary Options Appraisal, Environmental and Equality Impact Assessment work, the planned February-March 2026 public consultation, and the "on track and on budget" characterisation.
- Regional Transport Partnerships: 2025 Progress and 2026 Priorities Supports: Confirmation that continued Clyde Metro CFI development is listed as an SPT priority for 2026, and the verbatim "aiming to deliver a transformational mass transit system by 2027" wording flagged as an open item.
- Delivering better connectivity through mass transit in Glasgow Supports: Corroboration of Clyde Metro's multi-billion-pound, roughly 30-year scope and its potential to connect over 1.5 million people to jobs, education and health services.
