TRAINS between Glasgow and Edinburgh will not start until 11am on Sunday mornings.

And the rail route will stop at 8.30pm from Thursday to Sundays with buses making up the rest of the journey.

ScotRail has announced a new timetable to begin on Sunday, September 4 with changes to one of Scotland's main train lines.

The disruption is to allow for engineers to work on electrification of the railway.

David Dickson, ScotRail Alliance infrastructure director said: “Central belt electrification will allow us to run faster, longer, greener trains and cut journey times while increasing the number of seats available.

"The work we are delivering represents a huge investment in Scotland’s railway that will help transform travel on our network.

“We understand the inconvenience this work will cause our customers and every effort has been made to minimise disruption as much as we possibly can."

Trains between Glasgow and Edinburgh will start later on Sunday mornings and will only operate on part of the route between Sunday and Thursday evenings, after 8.30pm.

Buses will replace trains on portions of each route at these times.

Customers travelling from Glasgow to Edinburgh and back will be able to use train services to and from Glasgow Queen Street Low Level, via Airdrie and Bathgate.

Replacement buses will run on Sunday mornings before 11am from Sunday, September 4 to Sunday, December 4 and from Sunday, January 8 until Sunday, March 27.

After 8.30pm on Sunday to Thursday evenings, trains will run between Glasgow and Polmont only with replacement buses travelling between Polmont, Linlithgow and Edinburgh.

The service alterations run from September 4 until March 31, 2017 with a break for the festive period.

Mr Dickson added: "We are urging people to check their journey now and certainly before they set off.

"All of the information that people will need to plan their journey during these improvement works is already available on the ScotRail app and website.

"We will of course have extra staff on hand at key stations to assist customers.”

The move comes just weeks after previous disruption on the line came to the end.

Queen Street Station's high level was closed for 20 weeks for engineering works, reopening on August 7.

Routes between Edinburgh and Perth, Dunblane and Stirling are also affected, as are those between Glasgow and Inverness, Aberdeen, Dundee and Alloa.
