If they were to upgrade the 19, I would suggest the 19 to be brought under a revised 'Cobalt Clipper' brand and some refurbished Mercs (WiFi, USB, NSA) with a tagline something like the following:

"Links from the heart of Northumberland and North Tyneside to Cobalt"

They could then to save fuel maybe allocate some to the 310's during the evenings and the 309/310 on Sundays (as long as there's no football, concerts, payday weekends, nice weather or Christmas shoppers).

I wouldn't have said the 1 is a demanding route so why would they need a standard engine? They manage fine on 308 and presumably they are ok on the 21.
