THE board of NTV, Italy's first high-speed rail open-access operator, has unanimously denounced the behaviour of infrastructure manager Italian Rail Network (RFI), which it claims has unilaterally changed an agreement between NTV and RFI reached in January 2008 on which NTV's whole business plan is based. NTV sees this action as yet another attempt by RFI, which together with Trenitalia are subsidiaries of Italian Railways (FS), to prevent NTV from launching its high-speed services later this year.
