“Some of our normal facilities at Nottingham station will also not be available immediately.”
Head of the BTP response Supt Sandra England said: “Inquiries have been ongoing and we now have reason to believe the fire may have been started deliberately.
“Officers are working to identify anyone who may have been involved in the incident, and we are appealing for information from members of the public.
Passengers have been advised to check the latest travel information before setting off.
“While we will be able to run many of our normal timetabled services, there will continue to be some disruption in the next few days as a result of the fire.
The fire soon spread to the main concourse and the roof of the Grade II listed building, which had been recently refurbished.
“Thankfully, it appears that no-one has been injured. We will continue to support the investigation into the cause of the fire and would ask anyone who may have any information to contact British Transport Police.
