Some of the fleet maybe. Most are going to Great Western when the 700s are
in service.

They'll also be ETCS Level 2 on the Great Western*, meaning all GN\GWR fleets will have it installed.

The class 365s on the GN are being replaced by ex-Thameslink class 377/5 Electrostars on the conventional KX-Cambs/Peterborough/Kings Lynn routes, which in turn will be cascaded by class 700s on the Thameslink route.

The class 700s will work alongside the GN on the new intra GN-Thameslink services (i.e Cambridge-Brighton).
