SCOTLAND on Sunday speculated that the electrification of the Edinburgh Waverley – Glasgow Queen Street line would not be completed in 2016 and could be delivered up to three years late (News, 31 March).

That is not the view of Network Rail, the owner-operator of the railway, and the company that will be delivering the enhancements. We remain confident of completing the necessary electrification works, and other related infrastructure projects, between the two cities by 2016 as planned.

We are working closely with Transport Scotland, local authorities and wider stakeholders to plan for the delivery of this electrification programme, which will bring real benefits for passengers through faster, greener trains, improved journey times and more seats.
