I would summarise the service as A core hourly route, Newcastle to Plymouth via Leeds. At the north end, about half of the trains start back at Edinburgh and one starts back at Glasgow and one at Aberdeen. At the south end, one extends to Penzance. No servives to Paignton, Bath Spa or Cardiff via Bristol, and none calling at Weston-super-mare any longer. At least one short run only as far south as Bristol. Only one of these services calls at Gloucester.
A second core hourly route, Manchester to Reading, about alternate trains extended to Southampton. No extensions to Bournemouth of Guildford at all.
Hourly Nottingham to Cardiff, with a second train Nottingham to Birmingham
Two trains a day from Newcastle to Birmingham via Doncaster, one extended to Banbury.
