What are the main reasons for Northern opting to acquire 323s from WMR, rather than some of the spare 350s? The latter are more modern, have gangway connections and are generally better quality trains, so why have Northern gone for more 323s?
A few reasons spring to mind:
• Northern already had 323s so it would have been easier to supplement an existing fleet.
• 323s are much cheaper to lease.
• For most electrified routes in the North West 323s are much more well suited as they have better acceleration and faster door cycles. Blackpool to Liverpool and Manchester are very much the outliers of where 323s could be described as unsuitable, although it’s pretty likely that the 350/2s would retain their high density seating.
• At the time owners of the 350/2s had ambitions to convert them into OLE/Battery multiple units for use elsewhere.
• The additional 323s were to be a replacement to the 319s, still presenting an upgrade.
• Whatever they decided to use would have been replaced down the line anyway (circa 2030), so they might as well have taken on something that would have reached the end of their useful life at that point.
