Signal box Built in 1904, Princes Risborough North Signal Box, located towards the northern end of Platform 3, is the largest surviving Great Western Railway signal box in the country. It closed in 1991 when modernisation of the line moved signalling operations to Marylebone and became a Grade II listed building after a successful public campaign to save it from demolition.

Work had previously ceased in 1998 due to safety concerns but was resumed in 2013.
