Class 317/1, no. 317305 at Cambridge on 23rd May 2003. This unit was one of several loaned by WAGN to LTS Rail from 1996-1999, which involved the red stripe of the NSE livery being repainted green. This unit is now numbered 317505 and operated by Greater Anglia.

The British Rail Class 317 electric multiple units were built by BREL at York Works in two batches, from 1981-82 and 1985-87. They were the first of several classes of British Rail EMU to be based on the all-steel Mark 3 bodyshell, departing from the "PEP"-aluminium design which had spawned the earlier Class 313 to Class 315. The Mark 3 bodyshell was also the basis of Class 318, Class 455, and the diesel "sprinters" pioneered by the Class 150.
