Rail bosses plan to build Northern Ireland to Scotland tunnel

Irish Sea project is part of plan to improve transport links between four UK nations

Rail industry leaders have proposed building a tunnel between Scotland and Northern Ireland to a group tasked with exploring ways to improve connectivity between the four constituent parts of the UK.

High Speed Rail Group (HSRG) has proposed tunnelling under the Irish Sea between Stranraer and Larne in its submission to a review led by Sir Peter Hendy, who is expected to publish his interim report within weeks.
