BBC Scotland is reporting that strike action by ScotRail workers will take place on Monday 10 October after the RMT union rejected the latest pay offer.
There will be no services between Glasgow and Edinburgh and just a handful on three central belt routes.
An improved pay offer was made on Tuesday but the details of that were not made public.
The RMT union confirmed on Thursday afternoon that it would not be recommending members accept it.
ScotRail said only three services would be running during the day on Monday.
Next week’s strike is part of a wave of industrial action on the railways across the UK.
One involves a dispute by Network Rail staff who maintain the infrastructure, such as tracks and signalling.
They are unhappy about the future of jobs, as well as pay and conditions, and are due to walk out on Saturday, 8 October.
ScotRail is expect to run a limited daytime service on a number of routes around the Central Belt and the Borders including trains every 30 minutes between Glasgow and Edinburgh.
