There is disruption on trains to and from Largs and Ardrossan this afternoon after an incident in Glasgow.
A bus hit a low bridge earlier in the day, with services between Glasgow Central and Paisley disrupted as a result.
Newtork Rail said: "We're assisting the emergency services, who are responding to a bus trapped beneath a bridge between Glasgow Central & Paisley Gilmour Street.
"We need to complete a safety inspection of the bridge before trains can use it again, we can only do this once the bus has been removed."
Scotrail is attempting to run trains where it can but disruption may continue.
