Borders Railway bosses say they are continuing 'efforts to improve' after missing punctuality targets.
Results of the last rail four-week period from May 29 to June 25 2016 showed that only 45.5% of trains arrive at Tweedbank on time - the target is 64.8%.
But Train Operating Company ScotRail points out that the standard measure throughout Great Britain for measuring train service performance is the Public Performance Measure (PPM) - made up of punctuality and reliability.
On this measure, the results showed the showed a PPM score of 86.1% - against a target of 93%.
A ScotRail spokeswoman explained June had been a particularly difficult period on the line.
For the four weeks in question, we experienced two points failures plus one instance where a train had to be removed from service due to a fault with one of the doors. On another occasion a train was cancelled due to a driver being unavailable at short notice due to illness. These four incidents generated the most delays. We believe customers should have access to on-time stats as well as the industry standard figures, so we publish both on our website and at stations. We do our utmost to keep passengers moving and only cancel trains when we have exhausted every alternative. On this occasion, we did not meet our targets but will continue our efforts to improve." >
The Borders Railway that was re-opened for the first time since 1969, with 30 miles of extra track and costing £294 million is a vital commuter link between the Borders and Edinburgh.
A South of Scotland MSP, Rachel Hamilton, has been critical though, saying commuters on the line have been "consistently and persistently let down."
