Avanti

Avanti West Coast said all lines were blocked between Lockerbie and Carstairs and services would be affected until 14:00.

Strikes planned by Avanti West Coast train managers have been suspended to allow negotiations in a long-running dispute over rest day working.

The RMT described the latest postponement as a "breakthrough", while Avanti said it remained open to working with the union to resolve the dispute.

But Mr Lynch warned that Avanti must "demonstrate a real willingness to compromise" if it wanted to avoid an escalation of this dispute.

Avanti West Coast said it was pleased the strikes had been suspended.
