Advert The bulk of the work begins in March and will run until early June, with a full train service able to run once more from June 7, 2021. Trains will be able to run to and from London King’s Cross station for the vast majority of the work. Once works are completed in June, more than 6km of new track and over 15km of overhead wires will have been installed. Network Rail teams will make essential changes to the signalling and tracks in the area to allow reduced services to operate between February 26-28. For this work to be carried out safely, the following changes will be in place.
