Summer disruption for train commuters between Edinburgh and Glasgow
Commuters travelling between Edinburgh and Glasgow are due to have six weeks of disruption this summer.
Part of the main Edinburgh-Glasgow route, which normally takes about 50 minutes, will be closed from 13 June to 27 July.
Slower routes via Airdrie/Bathgate and Shotts will still run.
The Winchburgh tunnel in West Lothian is being closed as part of the £750m electrification of the line to enable faster and longer trains to run.
During the work, journeys are expected to take up to 50% longer than normal because trains will be diverted via Dalmeny, beside the Forth Bridge, then have to reverse on to another line.
ScotRail's new Dutch operator, Abellio, takes over the franchise in April from First ScotRail.
A Scottish government spokeswoman said: "The works are planned to commence during June 2015 and last for 44 days, and Transport Scotland continues to work closely with both Network Rail and ScotRail to minimise the duration of the closure."
