New Enviro 200's for Stagecoach North East

Stagecoach North East have taken delivery of their new Enviro 200's so I made a trip to South Shields to see them in action. They follow previous batches on Enviro 200 bodied vehicles in this modern fleet which now has an impressive low average age.
Previous deliveries of the Enviro 200 have included a batch of MAN 14.240's which, from the front, are visually similar. The emergency door position and window detail varies between the batches of Enviro 200's as can be seen from the photos below.
Further pictures of these vehicles and others in South Shields will be shown on our FocusFlickr site.
