DRS Class 20s Nos. 20308 and 20312 arrive into Princes Risborough station for a pathing stop to allow a fast Chiltern service to overtake. They are at the head of 1Z20, Pathfinder's "Buffer Puffer" tour, initial leg 05:05 from Crewe to Liverpool Street. Due to arrive at 07:54 they are running a few minutes early at 07:51 on Saturday 26th Janury 2013. The scaffolding does not improve the appearance of the station at the moment, but once the roof refurbishment is finished it should look good once again! Digital Image No. GMPI13794.
