Putrajaya had spent RM100 million to link KLIA and KLIA2 by rail and will charge users RM2 one way, because it is a form of public transport, said acting Transport Minister Hishammuddin Hussein. Speaking to reporters after visiting the Express Rail Link (ERL) station at KLIA2, Hishammuddin refused to respond to queries by the Public Accounts Committee (PAC) on why taxpayers ended up footing the hefty bill for the link.
