Production is underway in Glasgow on Nightsleeper, a shiny new thriller for BBC One. 
 

The 6 x 60 series is from writer Nick Leather and Euston Films, and is set in real time on a sleeper train, the Heart of Britain. 
 

As the Glasgow-to-London train hurtles towards its destination, two people, who have not previously met, must work together to save the lives of a group of passengers on board as events rapidly and dangerously escalate. 
 

Euston Films’ MDs Kate Harwood and Noemi Spanos executive produce alongside writer Leather and Gaynor Holmes for the BBC. The director is Jamie Magnus Stone; the producer Jonathan Curling. 
 

Leather said at the time of the commission news: “I couldn’t be more excited to work with Euston Films and the BBC to drive the engine of this real-time thriller and take our audience along for a ride full of personal intrigue, political manoeuvring and danger. By the time dawn breaks at the end of this journey, no-one involved will ever be the same again.”
 

Harwood and Noemi Spanos added: “The classic on-screen genre of a runaway train is given a thrilling modern twist by screenwriter Nick Leather and we find ourselves with a small group of people in a race against time.”
