Network Rail says "lessons will be learned" after a train derailment which is likely to cause two weeks of disruption.
Two trains involved in engineering work collided on Saturday. No one was hurt but the line between Dumfries and Kilmarnock is closed.
Katie Hunter reports:
Passengers travelling between Dumfries and Kilmarnock will face delays for the next two weeks, as work gets underway to repair the railway line.
The damage was caused when two engineering trains collided, leading to them being derailed.
At Dumfries station, there were mixed views on how the situation has been dealt with:
Last night on the internet we couldn't understand why there was no train service. We couldn't even pick up that there had been an accident. It's only this morning we've realised there was a train crash."
I believe there's two buses now, possibly delays to get to Glasgow, but I'll get the direct bus to Kilmarnock."
I heard yesterday that that is what happened, but somebody said there were putting buses on so that's fine."
Replacement buses have begun transporting passengers from Dumfries to Kilmarnock this morning, because of repairs to the railway line.
On Saturday (3 August) two engineering trains collided near New Cumnock.
No one was hurt, but for the next two weeks work will be taking place to repair the line, causing delays for passengers travelling between Cumbria and Scotland.
Scotrail says passengers travelling between Carlisle and Glasgow via Dumfries will face delays from Monday morning.
Two engineering trains collided on Saturday morning damaging the track. No one was hurt.
Trains between Glasgow Central and Carlisle via Dumfries will terminate at Kilmarnock and start back from Dumfries. Replacement buses will run between Kilmarnock and Dumfries.
A crane is being brought in to remove the wagons before the repairs can begin. The line is expected to be closed for about two weeks.
Once the derailed wagons have been recovered the repair work will take approximately three days to complete. Therefore it is expected that the line will remain closed for a number of days. During this time passenger services will start and terminate at Dumfries and Kilmarnock and freight traffic will be diverted via West Coast Main Line and Paisley.
Virgin Trains has cancelled all its West Coast mainline services on Monday and Tuesday ahead of an anticipated strike by Network Rail workers over the Bank Holiday.
Members of the RMT and TSSA unions have voted for a 24-hour strike, starting at 5pm on Monday, amid an ongoing dispute over pay.
In a statement on its website, Virgin Trains said that if the strike goes ahead as planned, then no services will run on either the 25 or 26 of May.
If this industrial action goes ahead, there will be no Virgin Trains services running on the West Coast Mainline on either Monday 25 or Tuesday 26 May.
If the industrial action is called off, some services will be reinstated but we cannot be specific at this stage.
Customers planning to travel on the affected dates will need to make alternative arrangements. If you are planning to travel on Sunday 24 or Wednesday 27 we recommend that you check before you travel for more information on how your journey may be affected.
A spokeswoman for the company told ITV News that East Coast services - which are run by a different operator - would continue on a reduced timetable, and advised customers to check for the latest updates before travelling.
She said bosses were monitoring talks between Network Rail and the unions to see whether the situation may improve.
Anyone with tickets for those dates can use them for either the Sunday or Wednesday, in line with any restrictions on the tickets bought.
The full statement, as well as details about how to get a refund, are available on the Virgin Trains website or by calling 0344 556 5650.
People travelling from Carlisle to Scotland, via Lockerbie, may be delayed by up to 20 minutes.
It's because of a train fault, and disruption is expected to last until 6pm.
Today, the Government announced plans to increase rail services in the North. But what does it mean for Cumbria?Read the full story ›
Cumbria County Council has welcomed today's announcement of what it calls "major changes and investment in the rail network'.
It says the tenders, which will commence in April 2016 and will last for a minimum of seven years, will affect the entire railway network within Cumbria.
Council Leader Cllr Stewart Young said that the changes were the result hard work done through years of lobbying by the council.
The rail services mapped out here will help transform the current second-class rail services Cumbria has been forced to live with through years of underfunding.
"The county council and Cumbria LEP laid out some very clear ‘asks’, and I am delighted that many of these have been answered.
"But there are still improvements we need and we will be working to influence the bidders during the bidding process so that we get the very best rail provision possible."
Windermere and the Furness Line will reportedly benefit from franchise plans announced by the Government this morning.
The new 'Northern Regional' service means that by December 2017, Windermere should have two trains per day to Manchester Airport from Monday to Friday.
It also means that the Furness line is expected to have eight trains a day to Manchester and Manchester Airport, as well as extra trains along the Cumbrian Coast that it's claimed will be timed to better serve workers' shift patterns.
The number of seats on trains in the North West is to increase by a third, under Government plans to reduce overcrowding on the region’s rail network.
There will also be an extra 200 services every day across the Northern and Trans Pennine rail franchises, which cover Cumbria.
Transport Secretary Patrick McLoughlin says that Pacer trains will be scrapped as part of the plans.
