Cambridge South will be the city’s third railway station and is being built next to the biomedical campus, which has 23,000 staff.
The letter from Katie Frost, Network Rail’s route director for Anglia, said it was “working closely” with the principal contractor “to integrate the replacement sub-contractor, reallocate resources to minimise the delay as far as possible and manage the remaining risks that remain to the programme”.
“We are confident that we can overcome these challenges and deliver the new station in June 2026 so that trains can start to call at Cambridge South,” she said.
“We will also continue to pursue all opportunities with our contractor to accelerate the delivery where possible and, if we are successful, we will aim to open earlier.”
Liberal Democrat city councillor Olaf Haulk, who represents Trumpington ward where the station will be located, said it was “really disappointing news”.
“The station is expected to serve around 1.8 million passengers a year. Its opening has already been delayed by several months – meaning more than a million journeys will now not be made by train, with many instead made by car.
“Residents in my area had been really excited about the station opening soon – and it’s just been dashed, again.”
