Grey's Anatomy and Trainspotting's Kevin McKidd in BBC drama

The Telegraph previously revealed that camera crews were on site at Finlaystone in Port Glasgow shooting scenes for an upcoming production set to be released later this year.

The national broadcaster has now confirmed that the location is being used for the CBBC feature-length special The Primrose Railway Children, starring Kevin McKidd.

The actor rose to fame as Tommy in Danny Boyle's iconic 1996 film Trainspotting, while he has enjoyed success over the past decade-and-a-half playing American doctor Dr Owen Hunt in the hugely-popular hospital-based TV series.

His latest work is based on Jacqueline Wilson’s novel of the same name, which is a modern reimagining of E Nesbit’s classic The Railway Children.

Filmed in and around Glasgow, the Highlands and heritage railways, the story follows Phoebe, her older sister Becks, older brother Perry and their mum who are living a comfortable life in Glasgow when suddenly they are uprooted and moved to the remote Highlands of Scotland.

Filming took place around the Old Laundry building within the grounds of the local estate - with a spokesperson telling the Tele: "It’s very exciting and wonderful that Finlaystone has been used for filming, showcasing the beautiful location in Inverclyde."

McKidd, who plays the children's father Rob Robinson, said: "I’m always so proud and happy to come home and work with the brilliant crews and talents that Scotland overflows with.

"I can’t wait to step into the character of ‘Rob’ and retell this reimagined British classic story alongside such an exciting cast.

"It will be a cinematic treat for the family.”

Tali Walters, creative director at BBC Studios Kids and Family productions, said: “We are proud to be making this dramatic and ambitious production in Scotland with all it offers in terms of locations and talent, and very much looking forward to sharing it with families across the UK and around the world.”

The production is due to air over Christmas.
