One board on the 688 service runs onto scholars service 141, which requires seatbelts, so MPD 618 is allocated to this board at present. As this vehicle was refurbished specifically for this purpose, I cannot see this allocation being changed, but if 618 is VOR, one of the new Optare Solos will be allocated in its place, to fulfil the contractual requirement of seatbelts on the 141 service.
In my opinion; it would make sense to allocate three of the five new Solos to the boards on service 74, which interwork with service 686 and 687, as well as scholars 112, as these are the more 'long-distance' services which would benefit from improved reliability. One of these boards also runs onto service 688, so it would keep the seatbelt specification consistent on this service. I would then allocate one to services X81/681/185, as the new Optare Solos should be more reliable than the present MPD allocation, and another to service 682.
This would mean that an MPD would continue to be allocated to service 683, with two MPDs remaining as spares.
Think that the 74 is now stand alone and doesn't interwork with 686/687 anymore
