Travellers in the UK are bracing for the first of three days of rail strikes starting Monday night.
Members of the transport union RMT (Rail, Maritime and Transport workers) will be walking out on 21, 23 and 25 June, with reduced services on those days and days beside the strike days.
As RMT includes signal workers, the whole rail network will be impacted.
A temporary timetable with around 20% of normal service will be running, per Network Rail's limited service train timetable.
The reduced timetable means for instance that Scotrail will be running two trains an hour between Edinburgh and Glasgow (via Falkirk) between 0730 and 1830.
"We expect significant disruption across our network," Scotrail warns. "Most of our routes will be closed and we will only be able to run a severely reduced service, so we strongly recommend you plan ahead, and only travel if necessary on these days.".
RMT is striking over cuts in transport funding (Network Rail is state owned) demanding a rise in pay in line with UK rpi inflation. RPI inflation hit 11.1% in April.
Travellers who are impacted by the strike should be eligible for a ticket refund, says Network Rail.
