Engineering works are set to disrupt seven weeks of train travel for passengers at Bishopbriggs and Lenzie this summer.
The main route between Glasgow and Edinburgh will have replacement buses in effect near Linlithgow, as the Winchburgh tunnel is closed in preparation for electrification of the line from Saturday, June 13, until Monday, July 27.
Anyone travelling to Edinburgh will change trains at Croy for a service to Linlithgow and will then have to board a third train via a diverted route or take an express bus to the city centre.
For the return journey back to Glasgow, or Lenzie and Bishopbriggs, passengers will be able to take a low level service via Airdrie and Bathgate, a journey which takes longer to travel.
A ScotRail spokesperson said: “We will have extra staff at key stations to guide passengers to the next available travel option.
“We are advising commuters to set off earlier than normal as most journeys will take longer.
“Some people may be able to amend their travel times so that they can use trains that are less busy.”
Normal fares will apply for these diverted journeys. For up-to-date travel information: scotrail.co.uk/winchburgh
