ScotRail warns of 'significant disruption'published at 08:21 British Summer Time 4 August

David Ross of ScotRail has been speaking to BBC Radio 4's Today programme about the major disruption facing passengers today.
There are speed restrictions across the whole network because of the amber weather warning, he says.
"That means we will operate significantly fewer services than we normally would, and across a number of routes there will be no services at all throughout the course of the entire day."
He says the advice to passengers is to take a look at the ScotRail website or the app, to see exactly what’s running and when.
