As Minister for Transport, I have responsibility for policy and overall funding for public transport.
The National Transport Authority (NTA) has statutory responsibility for developing an accessible, integrated and sustainable public transport network. It is the individual transport companies, which have responsibility for the operation of public transport services, in conjunction with the NTA.
In light of the NTA's over-arching responsibilities in relation to public transport accessibility, including in relation to the accessibility of vehicles, I have forwarded your question to the NTA for direct reply to you. Please advise my private office if you do not receive a response within ten working days.
