With the Crossrail delay announcement, any update on replacing the 315s by shortened 345s
I assume many of them are going to need major maintenance if they were kept another 2 years, and any cost of removing and storing 2 cars of some more 345s must be negligible in comparison to work on 315s. Surely when the 345s were sold and leased back rental payments would start so why pay rental on these and pay to maintain the 315s at same time
I would have thought withdrawals would speed up now to complete changeover
with those in best condition (perhaps that should be less bad condition) covering on the West Anglia services instead of their worse ones seems likely.
One caveat is not yet clear on the Liverpool Street platform lengthening, and some would have been kept to cover Liverpool Street peak extras around the transition. However it now seems that even when the tunnel section opens may be a phased opening of connecting to it both ends. Not sure if Liverpool Street (platform 16-18) gets sorted during this phasing
