Upon rail privatisation in 1996, the Chiltern Railways franchise was won by M40 Trains, a consortium of a management buyout, Laing Rail (a subsidiary of construction company and PFI specialist John Laing plc), and venture capitalist 3i, and in 1998 the line between Princes Risborough and Bicester North was redoubled by the company. This included the total reconstruction of Haddenham and Thame Parkway at platform level, with two side platforms instead of the single platform constructed in 1987, and a new down platform at Princes Risborough, together with the raising of the speed limit. Also in 1998 the first Class 168 Clubman trains with a maximum speed were introduced to reduce journey times.
