ScotRail trains cancelled north of Inverness on Far North Wick and Thurso and Kyle lines
Train services north of Inverness are being cancelled after a signalling fault at Muir of Ord.
ScotRail passengers onboard the 5.12pm Inverness to Ardgay service, due in at 6.40pm, were first to be affected with customers disembarking at Muir of Ord.
That train has now been sent back to Inverness where it will terminate.
The 6.31pm train north out of Inverness, the last service heading for Wick, was also cancelled.
At present, ScotRail says no replacement buses have been booked
With the disruption likely to last until 9pm at least, all passengers on the Far North and Kyle lines are advised to check their journeys.
A ScotRail spokesman said: “Due to a fault with the signalling system at Inverness disruption is expected until 21:00.
