Thomas and his friends return in the complete Series 15! With the Sodor Search and Rescue Centre up and running the race is on to become the ‘Sodor Search and Rescue Engine’. Thomas takes Bertie on a rail adventure and soon runs into trouble on the Shake Shake Bridge. There are twitters and tweets, clanging bells and wonky whistles, giant escaping balloons and sticky magnets. Percy makes some new friends and the engines are rewarded for being Really Useful.
