Network Rail's New Measurement Train is not a frequent visitor to the Chiltern line but was out on Thursday 21st February 2013. It was working as 1Q16, 07:55 from Derby, eventually to Old Oak Common, though it departed from Derby 174 minutes late! Missing out various pathing stops en route to Paddington via Oxford and Reading it made up much of the time but encountered more delays between Paddington and West Ruislip. By the time it passed through Haddenham & Thame Parkway at 15:36, seen here, it was around 56 minutes late on its way to Banbury, with 43013 and 43014. From Banbury it worked back via the Chiltern line to Old Oak Common. Digital Image No. GMPI14232.
