During the final days of first generation DMUs in the Thames Valley, various odd formations, and previously unseen classes of DMU were pressed into service with Network SouthEast. One such short lived set was L490 (51572, 59734 & 53599). This Class 108/115/108 set only seems to have been in use for a few months. It is pictured here accelerating away from Goring on 27 May 1992 with the 2C72 19:15 Reading to Didcot Parkway service.
