A few Class 104 vehicles spent a very brief period at the end of their careers working Network SouthEast services in the London and Thames Valley area. In true Western Region tradition they even acquired set numbers. On 20 May 1992, 53477 leads a mixed Class 104/101/117 formation as unit L408 past Didcot North Junction with the late running 17:35 Reading to Bicester Town service. One of the expressions that older people are supposed to use is 'I remember when all this was fields'. I am obviously old, as I clearly do remember when the area around Didcot North Junction was all fields! A large housing estate now occupies the field in the background, while there is now an industrial estate in the field to the right.
