In the class 701 discussion
www.railforums.co.uk
it was suggested slightly tongue in cheek that given the ongoing class 701 delays that the 507s and 508s could be sent to SWR once they have finished on Merseyrail.
Would this actually be a good idea? Can they be re-formed into 4 car units? Or is this a solution looking for a problem?
Class 701 'Aventra' trains for South Western Railway: progress updates
surely not different doors to 720's which regularly do 100mph I believe the issue has been the cab doors which are different on 701s.

At this rate, the 507/508 going for scrap soon will be sent to SWR as back ups.
