Passengers are suffering “substantial inconvenience” from a series of faults plaguing Scotland’s newest railway, with disruption nearly every day so far this month.
A log of incidents shows more than 80 trains have been cancelled or delayed on the Borders line since 31 March.
They include a range of faults to the signalling system, which was installed during construction of the £350 million Edinburgh-Tweedbank line, which opened last September.
One such incident led to nearly half the trains on the route last Saturday being cancelled or delayed.
Other difficulties include “crewing issues” – staff shortages – and trains breaking down.
Most services on the 35-mile line are operated by ScotRail’s least reliable train fleet.
The Campaign for Borders Rail (CBR), which compiled the log, said passengers were further disrupted by delayed trains not stopping at some stations to make up time.
