The alternative to vehicles moving from one location to another would be to allocate a vehicle which is of a higher specification than the contractual requirement? All of Jesmond's Optare Solos are Euro 5, so these would comply with the minimum contractual requirement.
Go North East has the upper hand with readily-available Euro 4+ minibuses in North Tyneside, and luckily for them, both vehicles depart from North Shields as their first run (18:56 and 19:56 respectively) rather than Cramlington, reducing the need for vehicles to run light.
