Smart decision from SWR, albeit painful for commuters.
It will be well appreciated over the christmas season when training demands aren't quite as high as currently required.
I suspect with this plan, we will see a steady weekly diagram move over consistently very soon.
Short term pain, long term gain. Also wouldnt surprise me if SWR/DFTO buckle to public pressure, reinstate services only to backlash in the winter months when the 455s are dropping like flys and not enough drivers trained for the 701s.
