What they could even do to replace the Pronto at Crook is this if the TEN series could be timetabled so that all Hexham journeys are Hexham operated and all journeys to Low Prudhoe and Rockwood Hill are Riverside operated:

- 8 + 1 spare new E400MMCs to Riverside for services 10A / 10B.
- 6071 to 6076 to Hexham for service 10 alongside 3942 as a spare.
- 6077 to 6083 to Crook alongside 3941 from Riverside for Pronto services.
- 6084 to Riverside as a permanent TTX spare vehicle.

This is what the numbers from Riverside, Hexham and Crook would look like then:

Riverside
- 8x TEN branded E400MMCs for services 10A / 10B.
- 4x Red Kite branded B9TLs for service 47.
- 6x TTX branded B9TLs for services X9 / X10.
- 1x corporate liveried E400MMC as a spare for services 10 / 10B.
- 1x corporate liveried B9TL as a spare for services X9 / X10.
- 2x corporate liveried B7TLs as last resort spares for TEN / TTX and primarily service 47.

Hexham
- 6x TEN branded B9TLs for service 10.
- 1x corporate liveried B7TL as a spare for service 10.

Crook
- 7x Pronto branded B9TLs for services X21 / X46.
- 1x corporate liveried B7TL as a spare for services X21 / X46.

The spare E400MMC could be fitted with a Tachograph so that 6084 and or the spare E400MMC could be used on the X9 / X10 if needed. Also, this would allow GNE to test the E400MMC in tougher conditions and on arguably, it's toughest routes and if proved successful, GNE could then consider this as a future vehicle option for orders. Also, allocating E400MMCs to services 10A and 10B despite the routes not being too demanding, would allow GNE to test the capability of this vehicle type on various roads such as Stonyflat Bank, and the fast paced A695 and joining the A184 from the Teams and picking up speed on the incline towards the Askew Road Junction / Redheugh Bridge.
