DUBLIN Bus is aiming to revitalise its fleet next year with plans to purchase up to 170 new double deck buses.
The semi-state owned firm has begun searching for a company to supply the new vehicles in 2015.
However, any plan to get the new vehicles on to the streets is dependent on funding approval from the Government.
The move would mean a substantial rejuvenation of the company's fleet of almost 300 buses.
Dublin Bus purchased 80 buses for more than €27m in 2013 as part of a fleet upgrade, and the same number in 2012 for €26m.
It has now begun the search for a supplier of more than twice that number next year.
"The number of buses that may be bought is completely dependent on the amount of funding that may be made available to Dublin Bus," a spokesperson told the Herald.
The company usually replaces buses after they have been in service for around 12 years.
According to tendering documents, Dublin Bus is seeking a supplier for up to 170 new double deck buses. The buses are to be mixed two and three axle models.
"This procurement is subject to Exchequer funding approval and this process does not represent a commitment to purchase," the documents add.
According to a report published by the National Transport Authority (NTA) earlier this month, some 270 million journeys were made using public transport in Ireland two years ago, with over 50pc using bus.
Dublin Bus ferried 113.28m people or 42pc of public transport passengers in 2012, with Bus Eireann moving 28.63m or 10.6pc of people around Ireland.
Iarnrod Eireann carried 36.92m passengers by rail in 2012 and LUAS customers totalled 29.32m.
According to figures released in a report from the NTA focusing on commercial bus services in the greater Dublin area, roughly 75pc of all public transport trips in Dublin, were made by bus.
