Network Rail says hundreds of its engineers, as well as those from its supply chain, worked “night and day” while the West Coast Main Line was blocked for much of the period.
Improvements include London Overground power supply upgrades between Watford and Euston, new switches and crossings at Kensal Green in North London, new track and ballast near Tring, embankment strengthening in Harlesden, drainage worked near Leighton Buzzard, and re-tensioning overhead lines at Euston.
This should solve some of the issues that can cause delays in each area, Network Rail said.
Network Rail Capital Delivery head of track, Brian Paynter, said: “We’ve invested millions of pounds to improve future journeys on the southern end of the West Coast Main Line this Easter, at a time of year when we know passenger numbers are lower so we can minimise disruption to one of the country’s most important rail routes.

“In the long term though, our ongoing investments will see smoother and more reliable journeys and better facilities for passengers travelling to and from London Euston.”
