The number of passenger journeys on the Luas light rail system in Dublin has exceeded 50 million.

According to figures released by the company, over 80,000 people use the tram each weekday, representing a 20% increase on passenger numbers since 2005.

Construction work has begun at the Luas Red Cow depot to enable the extending of Red Line trams by a third.

It is estimated the extension, which is expected to be completed in 2007, will increase the capacity of all 26 Red Line trams by 40%.
