20302 and 20301 are the locos on one end of of 8X09, while 20304 and 20305 were on the other end. This train is the move of new LUL "S" Stock from Old Dalby to Amersham and Neasden and normally reverses at Princes Risborough at around 23:35. The train ran on Wednesday 30th March 2011, but apparently there was a loco failure at Princes Risborough so the whole train was stabled on the stub of the Thame branch in order to get it out of the way until the train could be rescued. The locos are seen shut down alongside the 0½ milepost on the Thame branch - not the easiest of spots to get any photos... 10:57, Thursday 31st March 2011. Digital Image No. GMPI8406.
