"Starting from Monday, passengers travelling on two trolleybus routes will find leaflets with key phrases in Lithuanian, English and Polish on board," said Daiva Malinauskiene, the project's co-ordinator.

The project, called "Learn on the Way", is supported by the European Union's Socrates programme and will initially run for one year.

Passengers will even be able to do homework and submit it for correction, said Birute Voveriene, spokeswoman for public transport company, Susisiekimo Paslaugos.

"There will be baskets in the trolleybuses where passengers will find exercises in the English and Polish languages. They will be encouraged to do the homework and to send it to the organisers," Voveriene said.

"The most active learners will be offered free language courses for special prices."

She also said a soundtrack with key phrases in English and Polish would be played in the trolleybuses to help budding linguists.
