It has meant journeys from Colchester to Ipswich, which normally take 20 minutes by train, instead take 35 minutes by bus. Journeys from Colchester to Harwich have instead taken more than an hour instead of 25 minutes. Weekend train services will return to normal from October. Simon Milburn, infrastructure director for Network Rail Anglia, said: “We’re really sorry for the disruption, but these four September weekends will give us the time to complete a series of vital jobs that we simply can’t get done while trains are operating. “A rail replacement service will run while Network Rail carry out these projects, and passengers are advised to check before they travel and allow more time for their journey.”
