Last Passenger

A doctor and widower named Lewis Shaler (Dougray Scott) heads home from London to Tunbridge Wells with his young son Max on a late-night train. A romantic connection begins between Shaler and fellow passenger Sarah Barwell (Kara Tointon). As the train approaches its destination, an unidentifiable man in a high-visibility jacket is seen outside, and another man crawling across the tracks. The driver's actions become increasingly erratic, leading to a desperate bid by passengers to stop the train.
