context_page_description: The British Rail Class 321 alternating current electric multiple units were built by British Rail Engineering Limited's York Works in three batches between 1988 and 1991. The design was successful and led to the development of the similar Class 320 and Class 322.
  Today the class is operated by Greater Anglia. Some have been converted to Class 320 and are operated by Abellio ScotRail.
context_section_description: In December 2013 Eversholt Rail Group rebuilt 321448 as a demonstrator at Doncaster Works for a proposed upgrade. It featured a new livery, completely refitted interior including two examples of sitting arrangements including 2+2 and 2+3, and a new First Class area. The demonstrator also featured air conditioning, not previously seen on Class 321 trains, along with fixed panel windows to replace opening windows and a new Vossloh Kiepe traction package.
  The production run covered 30 units. The Vossloh Kiepe traction package was installed at Wolverton Works with the rest of the work performed at Doncaster. The first was completed in December 2016. In 2017 the prototype returned to Doncaster to be modified to the same specifications as the production units, including being refitted with hopper windows.
