In glorious spring sunshine on 28 March 2012, 20227 & 20142 pass Rearsby with the 7X09 11:42 Old Dalby to Amersham underground stock move, comprising brand new S Stock units 21068 & 21067. 20905 & 20901 can be seen bringing up the rear. With not a cloud in the sky, and the train definitely running, it would seem that nothing could go wrong. However, just as the train came into view, a large piece of bright yellow farm machinery in the field behind the line decided to move into shot. Luckily it was travelling marginally faster than the train, and has just exited to the left!
