A new rail service between the north east of England and London had to be cancelled for a day when its lone train developed a technical fault.
Grand Central currently operates only one train
Grand Central's service from Sunderland to London, via Teesside and North Yorkshire, began on Tuesday.
However, the train was unable to leave its Newcastle depot on Thursday, due to what the company described as an intermittent fault.
Customers were assured the service would resume on Friday.
A statement on the company's website said: "The train is undergoing rectification and testing at the depot in Newcastle in order that it can be ready for action for tomorrow's service.
"We apologise for the inconvenience caused."
