And now here's my more serious proposal. I tried to map it out, but I believe that I have had little success in doing so.
Yuck.
The name would be
Northern Horizon.
Here is what it would basically look like:
1tp2h London Euston-Manchester Airport-Manchester Victoria-Salford Crescent-Bolton-Darwen-Blackburn

London services and Preston-Scarborough services would be operated by Class 350s where electrified and Class 180s where not, while the Tyne Valley services would be operated by Class 175s.
Livery would be burgundy with a gold GNER-style stripe and gold doors (with silver doors for First Class).
