Channel 5's On Demand service, Demand 5 is available to download on iTunes for iPhone, iPod Touch and iPad users.
The app which has been available since November 2011 offers the chance for viewers to watch their programmes right onto the portable devices.
This includes the ability to watch Thomas & Friends on the move when episodes are added time after time for viewing pleasure.
Currently, the Eighth, Ninth, Eleventh, Fourteenth and Fifteenth Seasons can be watched, with other series joining the service again just after their re-runned broadcasts.
Demand 5 is available for free download in the UK for iPhone, iPod Touch and iPad users on iTunes now.
