The Metro: A Rail Life Story

Tens of thousands of Newcastle United fans pass through the Metro for a home game on the first day of the new football season - and many of them are far from pleased with the club's owner. A guide horse undergoes training on the Metro system before moving to London, and in Sunderland, a crackdown on fare dodgers gets underway.

In the third episode, the Metro's ageing fleet comes under pressure when a train breaks down in a tunnel near its busiest station. Meanwhile, track inspection supervisor Wayne has his work cut out repairing decaying sleepers which, if not quickly replaced, could cause a train derailment. And customer service manager Alan has to shelve his plans for a quiet evening after he's called in to deal with an outbreak of anti-social behaviour on the Metro.

All hands are on deck as the metro system prepares for the busiest day of the year - the Great North Run. This year, a new and untested station in South Shields is at the centre of things. One of the event's regular runners prepares for a personal return to the course, as he runs in tribute to a friend.
