The buses are usually sold to school bus operators, tour bus operators and sometimes to bus enthusiasts
Dublin Bus is planning to sell 67 buses from its fleet this year as part of the company’s standard fleet replacement.
57 Volvo double deck city buses and 10 Dennis double deck city buses are to be put up for sale by the company.
52 of the buses were registered in 2003, while 15 were registered in 2002, the buses will be available from September.
The National Transport Authority(NTA) funds Dublin Bus’s annual fleet replacement programme, which aims to continue making efficiencies as newer buses tend not to require as much maintenance as their older counterparts.
The last time Dublin Bus made additions to their fleet was in 2016 when 100 new double-deckers were added.
Speaking to the The Irish Times, a spokesperson for Dublin Bus said that vehicles are replaced "when buses have reached the end of their cycle for our needs as a transport provider and to keep our fleet modern & environmentally friendly."
The buses can be sold to a variety of different organisations including school bus operators, tour bus operators and, in some cases, bus enthusiasts.
There will be some Irish buyers considered for the vehicles but most of them are likely to go to the UK.
Dublin Bus is allowing bidders to make an offer for one, some or all of the vehicles, with the closing date for the receipt of bids being 12:00am on Wednesday, the 10th of May.
