Train stations were deserted this morning and long queues formed at bus stations as the rail strike began to bite.
Severe disruption is expected on the rail network throughout today as a union takes industrial action.
Members of the drivers’ union Aslef will walk out for 24 hours in a row over pay.
No GWR trains to Devon, Cornwall or South Wales will run, and only one round-trip from Leeds to London will be in operation.
This latest round of industrial action involves drivers who are members of the Aslef union working at seven operators: Greater Anglia, GWR, Hull Trains, LNER, London Overground (Arriva Rail London), Southeastern and West Midlands Trains.
Schedules from the train operators who are involved are likely to be severely disrupted. But because Network Rail signallers will not be striking, other train firms’ services should operate normally.
