(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.
Make most sense for the E300s to be cascaded to Sunderland/South Shields, make them full single decker operations (if possible) and then move the E200s down to Hartlepool as the stand alone Midi fleet depot. Then I'm sure Mr Houchen and Stagecoach can make an arrangement of 30 something E10s for Hartlepool depot...
