But the service could be re-written to terminate Morpeth services at Newcastle with other DMU services running through instead.
And that would be a complete waste of money and is never going to happen. ThankfullyThe ruling linespeed round there is 110mph.
Roughly speaking, a 50mph speed restriction of approx half mile on an otherwise 110mph railway costs 2m20sec for a 250metre passenger train.
Having said that, a bypass would be about a mile shorter, which would save another 30 seconds (at 110mph). Therefore, 3 minutes, for about 3 miles of new railway (including a viaduct across a particularly sensitive part of the River Wansbeck.)
Also need to factor in the savings on all the fast trains not slowing down and then consuming power accelerating back up to 110mph over a 30 year payback period. Any one able to estimate that?And that would be a complete waste of money and is never going to happen. Thankfully
You have a point. Congestion relief is another one and the payback period is 60 years usually but has to have a good business case in the first place unlike HS2 which is being built with a very poor business case..Also need to factor in the savings on all the fast trains not slowing down and then consuming power accelerating back up to 110mph over a 30 year payback period.

Clean, modern but not very comfortable.
