In 2009, James May took to our screens to prove what is possible with classic toys. He undertook six challenges, including building a house from Lego and a bridge from Meccano.
Five of the tasks were completed, but one was derailed. James and his team are now revisiting the doomed challenge to make another attempt at building the longest ever model railway track - nearly ten miles long.
Linking two Devon towns, Barnstaple and Bideford, the last attempt saw no trains reach their destination.
This time the feat is bigger than before, as May challenges the two German proprietors of the world's largest toy railway museum to a race along the track.
The locals of both towns are galvanised once again, and James' old friend and railway enthusiast Oz Clarke turns up to lend a hand.
Simon, marketing manager of Hornby, said: “In this, "The Return to Bideford" aka "James May - The Great Race" you will be able to appreciate the blood, sweat, tears, joy, pain, exhaustion, drama and the sheer thrill of a group of likeminded Hornby employees and enthusiastic volunteers, laying a double '00' track on their hands and knees over almost ten miles between Barnstable and Bideford.
"Walking, stooping, running, pedaling and falling off bikes as the trains made their way between the two towns - witness the excitement of nation pitched against nation as UK and Germany go head to head."
