CLASS 321
|
One of the most successful modern EMUs is the Class 321 fleet, produced
by BREL York works for the then Network South East operating business.
The first 66 sets, classified as 321/3 were built for the Great Eastern
operating area in 1988-90. While these were being assembled a follow-on
order was placed for almost identical sets for the Euston-Birmingham slow
and semi-fast services, these were classified as 321/4. To supplement
the GE fleet, the final 11 of the 321/4 sets went to Great Eastern. |
