Sixty-six new colour light LED signals, 22 power-operated points and a remote computer-based signalling control system will be installed on the Wherry Lines routes from Norwich to Great Yarmouth/Lowestoft by Spring 2019 (RAIL 835).
Work starts this month, with a nine-day closure of the Great Yarmouth line from October 21 until midday October 30, while the Lowestoft line will operate at peak periods only.
It is part of a £68 million plan to replace some of the oldest semaphore signalling in the country.
Manually operated level crossings will be replaced by modern barriers controlled using CCTV cameras.
