Two questions regarding the deployment of these new 5-car trains:

1) are there routes on which they will completely replace the Class 465 and
466s?

2) if so, for those routes where the platform length limits trains to eight
carriages, will all current 6- and 8-car trains be replaced by 5-car trains,
or can they operate 10-car trains where doors on the two rearmost carriages
won't open at all stations?
