I agree, but it' not worth spending thousands and thousands on a proper first class area on 2 x 4 car 380s that will be used for around 4 months on the E-G before the 385s come into service.
I agree with you there but I fear that using the 380s in their current state would underwhelm the whole transition to electric services.
The chances are that the average passenger will think that the 380s are the oh so 'greener, faster, and longer' trains we all will know and love. The tabloids will have a field day next month when they start churning out their headlines citing the lack of full tables and genuine first class etc, then claim a few months later when the 385s are in service that the change in rolling stock was due to public pressure on ScotRail to 'reinstate them' on EG services.
All in all while passengers fortunate enough to sample the 380s will be, come the new year, accustomed to the electric rolling stock and slightly quicker journeys, any significant improvements which might have been percieved from the step change from 170s to 385s would be lost as a result of ScotRail's handling of the 380s temporary cameo.
As much as 380s are worthwhile in using as a stop gap, the lack of investment in them to bring the level of passenger facilities up to at least on par with what passengers on EG are acustomed to could prove to be an embarrasing marketing oversight.
