I don't see Hartlepool gaining anymore MAN E200s yet. Considering it's 8 years since Hartlepool last received any direct investment in vehicles, I wouldn't be too surprised if they gain direct investment this year.
The interesting bit about those Busways route are simple - bar Slatyford's 6/7/8, the Sunderland routes are the marginal routes at the depot. Compared to the 1, which is probably Hartlepool's second or third most-profitiable (which, given they only have 5 routes, might be seen as not much to sing about) and is the main direct interurban link between two major towns in the Tees Valley (which the 1 and 36 both link Hartlepool and Middlesbrough, the 36 is more a link between the 4 main towns).
