SCOTRAIL operator Abellio was “let off the hook” by being allowed to continue to run the service - despite repeated failures including late and cancelled trains.

Customer satisfaction targets were lowered two years in a row to avoid the Dutch firm failing to meet standards.

This would have allowed the Scottish Government to strip them of the franchise.

Scottish Labour’s transport spokesman Colin Smyth said the Scottish Government was allowing ScotRail to get “off the hook” over its franchise obligations.

He said: “Instead of hauling these chancers in and demanding they deliver what they are paid to do so by the taxpayer, the SNP Government let them off the hook and granted them a licence to fail.”

Transport Scotland said to end the contract would prove to be costly for taxpayers.
