L832 (51226, 59570 & 51499) passes non-stop through Sunnymeads station on 10 December 1989 with the 14:33 Staines to Windsor & Eton Riverside service. As can be guessed by the third rail, the line's normal motive power is 750V DC EMUs. The Network SouthEast DMU was taking part in the Windsor & Eton Gala Day, and whilst not as noteworthy as 50007 Sir Edward Elgar or Metropolitan Railway Bo-Bo No.12 Sarah Siddons, which were also taking part in the event, it was still just as much an unusual visitor. Unfortunately the weather was uniformly grim all day.
