Transport for London (TfL) is seeking 25 young people to record station PA announcements and go behind the scenes with the train network.

The invite is open to 'superfans' aged 5 - 16 to record special 25th anniversary PA announcements and gain exclusive access to parts of the network usually closed to the public.

To enter, participants must explain in 100 words or less why they are a 'superfan' of a particular mode of transport, whether it's the London Overground line they use to visit their grandparents, the bus route that takes them to football matches or the Cycleway they use every Sunday.

Twenty-five winners, chosen by the staff of each service will have the chance to record their own personalised 25th anniversary message for TfL, which will be played at a London station.

Winners will also enjoy a behind-the scenes tour that relates to their entry, such as depots for buses, cycle hire or trams, the IFS Cloud Cable Car or a Tube or rail station, and learn the secrets of how TfL keeps London moving every day.

A 'goodie bag,' with TfL 25th anniversary merchandise, that includes an iconic poster, will also be included.

The competition is part of celebrations marking 25 years of TfL, which kicked off with a lineup of buskers at Liverpool Street station, a silver 'TfL25' roundel and a collection of posters highlighting milestones from over the years such as the Northern Line Extension, Oyster contactless smart card and Night Tube.

London's Transport Commissioner, Andy Lord, said: "It's vital that London is a place where all children can grow up healthy and happy and fulfil their potential, with milestones from the last 25 years, such as free travel for young people, helping promote equal opportunities.

"As we celebrate TfL's milestone anniversary this year, this competition is a fantastic opportunity for children to get involved and for transport 'superfans' to make their mark and share their stories with millions of people across the capital.

"London is full of surprise and intrigue, and these announcements will allow us all to see the wonder of the city through children's eyes.

"It may even open their eyes to a fulfilling career in transport, and the array of award-winning apprenticeships, graduate schemes and internships we offer."

The competition runs until Wednesday 23 April and further details are available on the TfL Travel for Life website.
