Passengers have been left stranded after early morning train services were hit by a signaling fault.  

Commuters travelling between Ayr and Glasgow along with those on routes from Ardrossan, Paisley and Kilwinning have all been caught up in the disruption. 

Network Rail said that engineers were on route and that problems would be fixed “ASAP”.  

Replacement buses have been introduced on some routes, but not others.  

Passengers have been advised to expect delays, and to expect cancellations. 

Scotrail tweeted:  “We're dealing with a signalling issue at Paisley. Services are unable to run between Paisley Gilmour St and Kilwinning.  

“Network Rail staff are on their way. Bus replacement is not confirmed, we'd advise to make your own arrangements. Apologies.” 

The rail operator added: “Glasgow Central to and from Ardrossan, Ayr and Largs services will be subject to delays, alterations and cancellations.
