(Yesterday, 10:45 am)Storx wrote Hartlepool can't do full length vehicles because of the pits, so the only way they could do that would be upgrade routes elsewhere.
The likes of 3/4/7/8 at South Shields due to recent frequency cuts and interworking or the 23 at Sunderland would seem the obvious routes if you wanted to do something and then displace the E200's to Hartlepool. I'll let someone else choose, which ones.
Means everyone gets a little upgrade.
Hartlepool seemed to manage a few years back when they temporarily had a couple of MAN ALX300 running there. So there must be a way around it.
