Flooding at Golspie disrupts rail services between Inverness and Wick
Scotrail says services are being delayed by around 30 minutes following flooding on the Highland line.
The first service affected was the 8.02am Wick to Inverness service, which ran 37 minutes late from Invergordon.
The 10.41am Inverness to Wick service was held up by 30 minutes and there were similar delays on subsequent services to and from Caithness.
Scotrail has warned passengers to expect delays and the use of replacement bus services on some parts of the route.
A spokesman said: “There are delays of around 30 minutes because of flooding. We apologise to passengers for any inconvenience. Passengers are advised to check their journey before travelling.”
Network Rail, which owns and maintains the railtrack, said the flooding was not above track level but had forced train drivers to reduce speeds to 20mph.
A spokesman said: “The problem was first reported at roughly 9.30am with water gathering over a stretch of track near Golspie.
“It was about halfway up rail height but not above it, but after engineers inspected the standing water the line remained open but at reduced speed on that section.
“It is going to cause some issues throughout the day. Once the services have stopped, engineers will have more time togo in and improve drainage and make sure water doesn't build up further.”
