In 2014, a brand new challenge was devised, involving the Action Man doll. The idea was simple - to see if a toy (the doll in particular) could break the sound-barrier, and travel faster than the speed of sound (Mach 1) as a result, something that had not been attempted before with any existing toy.
Following James May's successful attempt to create a bridge out of Meccano in Liverpool back in 2009, a new challenge was made to see if the mechanical toy could be used to create a fully working motorcycle, and then ride it across the Isle of Man. More specifically, for one lap of the island's famous TT Course, in 2013.
James May reattempts his challenge to create the longest model railway line between Barnstaple and Bideford, but this time with a race between British model railway enthusiasts against a German team from Miniatur Wunderland. With sturdier track and a new power system, along with Oz Clarke helping out, the teams compete with three different model trains.
