Dozens of trains were cancelled on Sunday after a four-storey building in Union Street, close to Glasgow Central Station, caught fire.
The building has partially collapsed. Network Rail said the fire has been brought under control.
Several businesses said on Monday their sites have been "destroyed", while a local MSP added the damage "looks like something out of the Blitz".
A spokesperson for Network Rail said on Monday: "Glasgow Central Station remains closed following the fire in a building on Union Street on Sunday.
"While the fire is now under control, emergency services are still on site and we continue to support their response.
"The station will remain closed today and likely tomorrow. Timescales for reopening will only be confirmed once we are able to safely gain access and carry out the necessary checks.
"All services to and from Glasgow Central are currently suspended, and passengers should continue to follow alternative travel arrangements as advised by their train operators.
"We will provide further updates as soon as more information is available."
ScotRail said on its website that 15 of its 36 routes have been disrupted over the incident, with no trains calling at Glasgow Central.
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."
'Something out of the Blitz'
Paul Sweeney, Labour MSP for Glasgow, said on X that the building - which he notes dates back to 1851 - had partially collapsed.
"I hope the fire can be contained", he added on Sunday night. "The corner of the Forsyth Building, as well as the Caledonian Chambers and Central Hotel seem unaffected.
"It's a massive blow to Union Street with the restoration of the Egyptian Halls in prospect."
On Monday morning, Mr Sweeney told BBC Radio Scotland the damage "looks like something out of the Blitz" and that there are now concerns the remainder of the building will not be viable.
"There's the cafe, there's the Blue Lagoon (fish and chip shop), of course, which is famous for many Glaswegians. It's been completely wiped out, destroyed.
"I mean the building is a gutted shell... I spoke to building control officers last night on site. They don't have much hope that the building can be saved at all.
Businesses close after site 'destroyed'
In a statement on Instagram, a shop called Sexy Coffee said its business, located inside the building, had been destroyed.
"We are absolutely devastated to confirm that the shop has sadly been destroyed in the fire," the statement said.
"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."
The shop added "this is not the end", and said: "We will rebuild, revamp the shop, and reopen as soon as possible.
"In the meantime, our Argyle Street branch remains open, and we would love to welcome you there.
"Thank you to all of our amazing customers for your continued support. It truly means everything to us.
The owner of Willow Hair Salon confirmed on social media that "it looks like our entire building has been burnt to the ground" after the fire on Sunday.
Annabel said that the fire ripped through the back of the building - "it's f***ed basically, the whole thing", she added - before saying all her appointments for the week are cancelled.

A Scottish Fire and Rescue Service spokesperson said it was alerted at 3.46pm to reports of a building fire on Union Street.
"At its height, nine 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", the fire service said on Sunday.
In an update at 6am, a spokesperson said: "The incident has since been scaled back and nine appliances, including three high-reach vehicles, remain in attendance.
"There are no reported casualties, and crews remain at the scene."
Three men are bringing legal action against the former Sinn Fein president and are seeking £1 in damages.
John Clark, a victim of the 1973 Old Bailey bombing in London, Jonathan Ganesh, a 1996 London Docklands bombing victim, and Barry Laycock, a victim of the 1996 Arndale shopping centre bombing in Manchester, all allege Mr Adams was a leading member of the Provisional IRA on those dates, including of its Army Council.
Mr Adams denies that he had any role in the Provisional IRA and is opposing the claim.
On Monday, he arrived at the Royal Courts of Justice in London, wearing what appeared to be a bullet-proof vest, and was driven into the car park.
The court heard the three men want to show how Mr Adams was involved in the Provisional IRA "in the course of that conflict and to show on the balance of probabilities that he was as involved as the people who planted and detonated those bombs".
Opening her case, Anne Studd KC, representing the men, said Mr Adams was "directly responsible for and complicit in those decisions made by that organisation to detonate bombs on the British mainland in 1973 and 1996".
She said they are seeking £1 in damages against Mr Adams for "vindicatory" purposes and their case is "not a focus on their injuries".
In written submissions, Ms Studd said: "The defendant carefully draws a distinction between being a member of 'the Army' and being a member of Sinn Fein.
"In reality, the evidence will demonstrate that this was not the clear either/or choice as the defendant would have you believe.
"For many individuals, we say, including Mr Adams, that was a distinction without a difference."

Lawyers for Mr Adams said he "played an instrumental role in the peace process which culminated in the signing of the Good Friday Agreement in April 1998, which brought an end to the decades-long conflict".
In written submissions, Edward Craven KC, representing Mr Adams, said: "The defendant's alleged factual and legal responsibility for the claimants' injuries is strongly contested, as is the claimants' ability to bring these claims against the defendant several decades after the expiry of the applicable limitation period."
He added there was "no shortage of people with an axe to grind" who sought to discredit the former Sinn Fein leader.
Mr Craven claimed British officials, members of the Royal Ulster Constabulary or other republicans opposed to the peace process had an interest in discrediting Mr Adams.
The trial before Mr Justice Swift is expected to end next week.
Speaking after the first day, Mr Adams said: "I'm here to defend myself and to challenge the allegations being made against me."
"We will let the court get on with its business. But I would like to say for the record and at the outset that the only thing that I am guilty of is being an Irish republican committed to ending British rule in our country and seeking to unite the people of Ireland on the basis of freedom, equality, peace and solidarity."
The incident happened in the Beverly Hills area of LA on Sunday afternoon.
Police confirmed to NBC News in Los Angeles that the star was home with her partner A$AP Rocky and their three young children.
It is believed seven to nine rounds from an AR-15-style rifle were fired from a car - with at least four striking the house.
What appear to be bullet holes can be seen in photos of the front gate but no injuries were reported.
Police identified the woman as Ivanna Ortiz and said she remained in custody on $10m bail, according to NBC News.
Rihanna and A$AP Rocky share a daughter and two sons.
The Metropolitan Police said the 58-year-old was accused of three counts of murder as a crime against humanity, three counts of torture and one charge of conduct ancillary to murder in connection with his time serving as part of the Syrian Air Force Intelligence (SAFI).
The offences are alleged to have happened in April 2011, while he was leading a group that attempted to put an end to demonstrations in the village of Jobar, near Damascus.
The Crown Prosecution Service said it is the first time charges of murder as crimes against humanity under the International Criminal Court Act 2001 have been brought.
The man was arrested at an address in Buckinghamshire in December 2021 and was released on bail until Monday's charges.
The man, who now lives in the UK, is due to appear at Westminster Magistrates' Court on Tuesday, the force said.
The investigation was launched by the Counter Terrorism Policing's (CTP) war crimes unit.
Commander Helen Flanagan, who leads CTP London, said: "This has been an incredibly complex and challenging investigation, involving enquiries across many countries.
"This has required close cooperation with a number of international partners, as well as our colleagues in the CPS.
"The charges are extremely serious and show that we fully support the UK's 'no safe haven' policy in relation to alleged war criminals.
"Where we are presented with allegations of war crimes and crimes against humanity that fall within our jurisdiction, then, as we have shown here, we will not hesitate to investigate those rigorously and robustly."

It is understood CTP officers received a referral in November 2020 regarding allegations made against an individual in the Syrian armed forces in the early 2010s.
The 52-year-old double murderer died in hospital on Saturday after allegedly being attacked by an unknown inmate at HMP Frankland.
Huntley, who killed 10-year-olds Holly Wells and Jessica Chapman in Soham, Cambridgeshire, in 2002, had been in a critical condition in hospital after being hit with a metal bar on Thursday morning.
The former school caretaker was allegedly attacked in a workshop at the high-security jail in Durham. Police said earlier that their investigation into the circumstances of the incident is ongoing.
It is a longstanding policy for the prison service to contribute up to £3,000 towards basic funeral expenses for any death in custody.
The money is only permitted to be paid directly to a funeral director, and must be used to cover "reasonable costs" which include a "simple" coffin, a hearse, and cremation or burial fees.
It cannot be used for a headstone, flowers or order of service sheets, or other expenses considered "non-reasonable", such as hospitality related to any funeral or transportation for mourners.
Previous prisoners whose funeral costs have been covered include the Yorkshire Ripper, Peter Sutcliffe, in 2020, and Raymond Morris in 2014.
If Huntley's next of kin or family members have alternative arrangements, such as a pre-paid funeral plan, money from the state would not be used.
