Network Rail Chief Executive Andrew Haines says "it (strikes) could go on for a long time"

Train services across Scotland will be severely disrupted on Thursday and Saturday with only a handful of services running as rail staff take further strike action.ScotRail has warned passengers a very limited number of services will run on Thursday as a result of industrial action by the Rail, Maritime and Transport union (RMT) which has been locked in an ongoing battle over pay, jobs and conditions with Network Rail.Services will operate between 7.30am and 6.30pm and ScotRail has urged passengers to check services ahead of travel and only travel if it is necessary.The operator has also warned passengers to expect disruption on Friday August 20 and Sunday August 21 following the strikes as services are restarted.RMT picket lines will be in place at Glasgow Central and Edinburgh Waverley from 7am on Thursday, with a “picket at the fringe” at 10am on Waverley bridge.
