L418 (51443, 59507 & 51355) passes Swanbourne on 13 July 1991 with a Bedford Bletchley Rail User's Association & Oxon & Bucks Rail Action Committee special train from Oxford to Bedford. The train was organised to mark the 140th anniversary of the coming of the railway to Oxford. The long disused Swanbourne station can be seen in the background. Only the lead vehicle of this unit is a Class 101, which explains the L418 set number. 51443 is substituting for DMS 51397 out of the original Class 117 set L418.
