The controversial arrival of TVs on West Midlands trains has turned many passengers into critics - loud and angry ones.

But now Central Trains is looking to harness these faculties with a film festival which the captive commuter audience will judge. The company believes The Rolling Stock Short Film Festival will be the first such movie event held in transit.

It is being launched in conjunction with Channel Four's Ideas Factory and will see more than 100 five-minute films being screened on Central Trains services in the West Midlands throughout June.

Playing to an audience of over 70,000 people on the Cross City ( Redditch to Lichfield) and Coventry to Wolverhampton lines, passengers will have the chance to text vote for their favourite film, with the most popular short film taking home a cash prize and film-making equipment.

Dan Jones, Ideas Factory editor, said: "We are looking for both new and experienced film enthusiasts from all backgrounds to help us create an entertaining and inspirational schedule for our travelling audience."

Televisions were introduced on Central's 323 electric trains in June 2004 but, despite the introduction of Quiet Zones, some passengers still complain about the noise.
