Rory O’Neill, Transport for London’s general manager for London Overground, said: “Major investment in modern signalling is key to ensuring we can continue to offer a safe and reliable service while maintaining sufficient capacity to meet the growing demand for our services.
“There will also be some weekend closures in the same area before and after the October half-term closure.”
Previous system amendments between East Croydon and London Victoria in 2022 saw signalling related delays cut by more than a half with rail operators hoping for the same success this round.
