In what sense is GBR different from the Strategic Rail Authority with Network Rail tacked on? The operation of services and ownership of rolling stock will continue in private hands, so the industry continues to suffer from lack of vertical integration. And does GBR take over the powers (and staff) of DfT rail group and the Office of Rail and Road? (if not, it will vanish into the same contested spaces as the SRA did, never to be seen again!)
