from Balloch to Motherwell via Whifflet Line Developments In 2006, Network Rail announced tentative proposals to electrify the Rutherglen - Whifflet section, as part of a £1.4bn upgrade to Scotland's railways. The main benefits of this scheme were to provide an enhanced frequency for the Whifflet to central Glasgow routes and to provide an electric diversionary path for long distance WCML services. The new timetable came into operation on 14 December 2014, the Whifflet Line has been added to the Argyle Line system with services through Glasgow Central Low Level to the western suburbs.
