Chinnor & Princes Risborough Railway

The Chinnor & Princes Risborough Railway operates services on the surviving section of the 8 mile Princes Risborough-Watlington branch. The Princes Risborough-Chinnor section had survived in use as a freight only link to a cement works. Starting out at Chinnor station in 1990, services have been running since 1994, with three extensions in 1995, 1996 and 2018 bringing the line back to the national rail network at Princes Risborough..

Chinnor is a modest single platformed station whilst Princes Risborough station is the opposite, with heritage services accommodated in the station's platform 4, utilising a cross-platform interchange with "mainline" services.

The line has hosted first a Class 122 which was replaced in 1997 by a Class 121. The line’s modest size makes it ideal for single unit use, and DMUs are often employed on the first train of the day, which is booked as diesel operated.

In 2013 a second Class 121 was aquired with the intention of supporting and strengthening the exisiting unit and two years later a Class 117 was also bought as a source of spares.
