The Metro: A Rail Life Story - Season 1 Episode 4 -

In the fourth and final episode, all staff leave is cancelled on the Metro's busiest and most colourful day of the year as the Great North Run comes to town. 

It's a big day for station delivery manager Lynn Dickinson who has managed the event a dozen times before - but this time it's different with a new, untested station at the centre of it all in South Shields. 

It's an emotional day for one particular runner, Colin Burgin-Plews – known as the Big Pink Dress man for the colourful attire he usually wears while taking part in the event – this year running in memory of a friend.
