Just thought about this.........but maybe they've repainted the X93/X94 into Sapphire to bring some "commonality" should the inevitable cascade for them happen.

It would make sense to purchase new vehicles for the X93/X94 given the B9TLs still have some useful life left in them and would be ideal candidates for the X20.

If new vehicles were ordered for the X15, X18, X21, X22, X93/X94, the primary vehicles released would be:

- 12x E400MMC (10x 308, 1x Blyth spare, 1x Ashington spare)
- 15x E400 Classics 2014/2015 (12x 43/44/45, 3x Ashington - X14)
- 6x Volvo B9TL (4x X20, 2x Float spares)

The above in turn would then further release..............
- 10x 2011/2012 VDL DB300 Gemini 2
- 11x E400 Classics (7501-09 & 7511-12)
- 4x E400 Classics (7514-17) - would still be useful as spares or lower key work
