It all depends on which 150's have life left in them. Some may have a lot more mileage left in them than others.Silly question but given what has been said above, how long do we have for new rolling stock to enter service before serious timetable reductions have to be made?
E.g. let's assume the new tram trains are further delayed (there was a comment in another thread about them not being out on tests for a whole because of wheel issues). If the 150s are being withdrawn regardless then what happens?
There's 24 756's, 12 231's and 34 150's. So if it came to it the Flirts can cover for the 150 replacements without needing the 398's. It will mean that 197's will remain on Maesteg/Ebbw Vale services which will mean the plans of 4-5 car on all Manchesters may be pushed back.
It's clear to see it's been a bad week for unit availability, but it's not as bad as some are making out. The sooner 756's are in the service, the better.
