SNP MINISTERS were accused today of “shifting the goalposts” to save Scotland’s national train-operating company from losing its contract for poor performance.

ScotRail’s serious delays and cancellations are its worst in 20 years, according to a report published last week.

The Scottish government had set a performance target of 92.18 per cent, but only 88 per cent of trains arrived within five minutes of the scheduled time between August 19 and September 15.
