Though our plans are to electrify the entire route, the current programme, predicated on our average annual implementation rate of single track kilometres, indicates that we may only be able to electrify the section from Aberdeen to Inverurie by 2035. That will facilitate local cross-Aberdeen electric services. However, as new, innovative approaches develop, the pace of implementation and the industry’s capability to deliver may increase further and thus allow us to achieve full electrification of the route by 2035. As that increased pace is currently unknown our planning assumption is that alternative bi-mode traction, capable of achieving the speeds necessary to deliver our improved journey time aspirations, will be required to operate on the route as an interim measure with an expectation that the route, with an extension to Tain, will be fully electrified in the years shortly after 2035.
