Update as at October 2026
The best that can be said is that the RTS appears to be continuing. The latest update from the RTS team itself is from May 2026, see above.

The update states “We aim to submit it [the revised outline business case] to Defra and HM Treasury before summer 2026, for their approval.” A subsequent update provided to the Spelthorne Partnership Assembly (14 Sep 2026) mentions a £17M funding to keep the project alive. It also predicts submitting the business case to Defra in the “autumn” [of 2026]. So the project is slipping further.

Note this is only an “outline” business case. Previously we had been tracking the anticipated date for the Development Consent Order (DCO) application, not a new business case. That DCO application date must now be a long way ahead.
