Although I have got a reasonable number of pictures of Southern EMUs in the attractive 'Jaffa Cake' livery, they are mostly Class 411 4-CEP units. This is my only picture of a Class 421 4-CIG in this colour scheme. 1708 brings up the rear of the 15:04 Bognor Regis to Victoria service at Salfords on 15 March 1986.
