There is widespread damage and 42,000 homes remain without power after Storm Amy swept across Scotland overnight.

Despite Met Office warnings, Network Rail said the high winds hit “much harder and more quickly” than it expected – with fallen trees, flooding and debris blocking lines.

Scottish and Southern Electricity Networks (SSEN) said it had reconnected 33,000 properties, but work continued to be impacted by weather conditions.

An amber weather warning remains in place until 21:00 in the north of Scotland, with a wider yellow warning extending to northern England and parts of Wales until midnight.

Network Rail Scotland said there were more than 170 incidents, including 60 in the first two hours of the storm.

Several lines in the north of Scotland had been closed ahead of Storm Amy’s arrival, after Met Office alerts were issued earlier in the week.

However, the railway operator said it was forced to close all lines out of Glasgow and routes in southern Scotland without warning on Friday evening, when the storm hit harder than it expected.

Ross Moran, route director at Network Rail Scotland, said: “Our teams are working tirelessly to assess the damage, inspect the railway.

“Safety remains our top priority. We must ensure our teams can work safely on the ground and confirm that lines are secure before passenger services can run.”

Gusts of 96 mph were recorded on the Island of Tiree at the peak of the storm.

All Scotrail services out of Glasgow Central and Glasgow Queen Street low level were suspended until lunchtime on Saturday.

It said there were about 80 trees brought down on lines and engineers were checking routes before resuming services.

SSEN said power had been restored to 33,000 homes but warned further weather disruption was expected later.

Fraser Wilson, of SSEN, told BBC Radio’s Good Morning Scotland programme: “We expect because of the extent of damage to the network and conditions we are still going to be facing today that this will take some time, this storm is not over by any means.”

Winds of 60-70mph are forecast with occasional gusts of up to 85mph also possible, so some damage is still likely throughout Saturday.

In Aberdeenshire, about a dozen passengers were stranded on a train that hit a tree on the line from Inverurie to Aberdeen on Friday evening. No-one was injured.

Several flights and ferry services were cancelled, while some road bridges are either closed or have restrictions on high-sided vehicles.

A number of ferry crossings between Cairnryan, in Dumfries and Galloway, and Northern Ireland were cancelled.

The junior and mini Great Scottish Run in Glasgow, due to take place later, have been cancelled due to the weather warning.

Organisers said the strong winds and rain would create a risk of debris for the event on Glasgow Green.

The Met Office said that Storm Amy set a new record for the deepest area of low pressure in the UK for October.

The earth’s atmosphere exerts pressure on the surface and is measured in hectoPascals (hPa), also called millibars.

Storm Amy showed central pressure of 947.9hPa at Baltasound, Shetland. This exceeds the previous record of 950.9hPa in 1988.

In an area of low pressure the weather is often unsettled.
