Following the negative reaction in some quarters to earlier EMUs built in the 1980s the Class 321 had a deal of attention paid to its external appearance with the aim to produce a train "eye catching" on the outside and comfortable on the inside [3].

The original NSE batch became known as the 321/3 with the London Midland batch the 321/4 (theese haved more first class seats than the 321/3s [4]). The Yorkshire units were designated 321/9, unlike the other sub-classes these units did not have first class seating and so had 2 DTSOs instead of a DTCO and a DTSO.
The Class 321 is now only still in service with Greater Anglia on the Great Eastern route, thirty of the units receiving a "Renatus" refurbishment and upgrade which included new air conditioning, seating and wi-fi. However, despite the upgrade Greater Anglia are replacing the Class 321 with the Class 720.
Some Class 321s are to be converted for hydrogen fuelled operation and will be known as the Class 600.
