168112 passes milepost 24 near Oddington, on the upgraded Bicester to Oxford line on 26 August 2016. It is working the 1T48 16:50 Marylebone to Oxford Parkway Chiltern Railways service. Prior to the reinstatement of double track this photographic vantage point did not exist. The bridge from which it was taken replaced a level crossing. Apart from a few small gaps the line was bordered by trees and large bushes, so this is a very rare instance of a line actually improving enormously for photography.
