The Ashendon Junction to Grendon Underwood section, being Great Central territory, was designed in that company's style, which included the signalbox at Ashendon Junction. Intermediate stations on the section were Wotton and Akeman Street; these were also lavish structures. Goods facilities on the line were relatively limited, except at High Wycombe, in recognition of the fact that local goods traffic was unlikely to develop vigorously. The early train service was dominated by GWR trains from Paddington to Oxford and Aylesbury and GCR long distance expresses and local stopping trains.
