A building yards away from Glasgow Central Station has collapsed after a huge fire ripped through it, bringing all train services to a halt.

The fire, which started in a vape shop, has sparked chaos for rail passengers and drivers after Scotland's biggest city came to a standstill.

Glasgow's Union Street was closed off on Sunday evening when the blaze broke out in a building adjacent to the station. 

The dome on that building has now completely collapsed after the fire spread through it. 

The station has been closed 'until further notice' and evacuated, while traffic was brought to a standstill in the city centre.

Travel disruption is expected to continue throughout today.

National Rail have now confirmed the station will remain closed with 'no estimate on when it will reopen' and that no services will run in or out of the station. 

A spokesman added disruption is expected to continue on routes to, from and through Glasgow Central until 'at least the end of the day'.

Thick smoke billowed through Glasgow as 15 fire engines, along with police officers and ambulances attended the fire, which is said to have started in a vape shop.

The four-storey Victorian building was built in 1851 and pre-dated the station. 

It was designed by architect James Brown of the firm Brown & Carrick.

Fire crews continued to tackle the fire five hours after it began. By early Monday morning, the fire appeared to finally be under control.

However, nine appliances remain at the scene and members of the public are urged to avoid the area where possible.

MSP for Glasgow Paul Sweeney said on X that the Forsyth Building had collapsed. 

He told the BBC that he 'felt sick to see another part of Glasgow's built environment destroyed.'

He wrote on X: 'It's a massive blow to Union Street with the restoration of the Egyptian Halls in prospect.' 

In a statement at 6.45am today, a Scottish Fire and Rescue Service spokesman said: 'Operations remain ongoing and there have been no reports of casualties.'

The train station itself does not seem to be damaged.  

A coffee shop that was based in the building that has collapsed, Sexy Coffee, posted on social media: 'We are absolutely devastated to confirm that the shop has sadly been destroyed in the fire.

'It is heartbreaking for us and our team, especially after the support and loyalty we have received from so many of you over the years.

'However, we want to reassure everyone that this is not the end. We will rebuild, revamp the shop, and reopen as soon as possible.'

The owner of Willow Hair Salon confirmed on social media her business had also been destroyed. 

The fire had been reported via 999 just before 4pm, and saw several streets closed, including parts of Union Street and St Vincent Street, while the large Voco Grand Central Hotel located inside the train station was evacuated.

Among the crowds watching the scene unfold was Yvonne Kelly, 51, from Rutherglen, who said: 'It's not something you expect to see. I first realised there was a fire when I was on Buchanan Street, and could see smoke - I was wondering what was going on. When I got closer, I thought, "this is going to cause chaos".'

Ryan Dawes, 46, who works on Union Street, said he had left the building for a break when he became aware of the fire. 'I saw people running past looking quite panicked, and a lot of black smoke - it looked quite dramatic.'

On Sunday night, First Minister John Swinney said in a post on X: 'I am deeply concerned about the fire near Glasgow Central Station tonight and very grateful to all of the emergency services who are responding.

'Please continue to follow travel guidance, avoid the area and stay safe.'

Paul Sweeney said the building - which housed the vape shop where the fire started - had partially collapsed.

'Sadly the building has now partially collapsed. I hope the fire can be contained. The corner of the Forsyth Building, as well as the Caledonian Chambers and Central Hotel seem unaffected,' Mr Sweeney said.

'It's a massive blow to Union Street with the restoration of the Egyptian Halls in prospect.'

A Scottish Fire and Rescue Service spokesman said yesterday: 'We were alerted at 3.46pm on Sunday, 8 March, to reports of a building fire on Union Street, Glasgow.

'At its height, 15 fire appliances and specialist resources were mobilised to the area, where firefighters are currently working to extinguish a fire affecting the ground floor of a four-storey building. 

'There are no reported casualties, and crews remain at the scene.'

Police on Sunday evening warned people to avoid the area if possible, and said residents should keep their windows closed.

Some ticket acceptance is in place, with Avanti West Coast passengers able to use their tickets at no extra cost on LNER services between Edinburgh and London King's Cross. 

No trains will run to or from the high-level platforms at Scotland's busiest station, while trains that run through the low-level platforms will not call at Glasgow Central.

Avanti West Coast advised passengers an amended train service will run to Preston, Carlisle and Motherwell, 'enabling customers to connect with trains to Edinburgh and local services to the Glasgow area'.

ScotRail warned of substantial disruption to its services and urged passengers to check for the latest information before travelling.

It said that no ScotRail services will operate to or from Glasgow Central high level today.

ScotRail services will not call at Glasgow Central low level but will pass through the station to stop at Argyle Street and Anderson.

Mark Ilderton, ScotRail service delivery director, said: 'We are sorry to customers for the impact this will cause, and we would urge them to check their journey options before they travel, and be aware there will be very limited replacement transport.'

TransPennine Express said its services would not run between Glasgow Central and Liverpool Lime Street or Manchester Airport today, while trains between Edinburgh and Newcastle or Manchester Airport will be subject to delays and cancellations in both directions.
