165102 speeds past Didcot North Junction on 3 September 2014 with the 1P41 12:01 Oxford to Paddington First Great Western service. This train is taking the Didcot avoiding line, as it is a limited stop (Reading and Slough only) service. The equivalent train 30 years ago would be ten Mk 1 coaches hauled by a Class 50. I'll leave you to consider which is the better option!
