It seems a regular occurrence for Solos on the Darlington MAX services, although with 4645/4648/4655 being kept local and 4651 on long term VOR it's quite clear why those services have the rare allocations.

It would make sense to allocate either the Gas Buses or the Wright StreetLites as suitable spares, rather than use the Optare Solos which end up overcrowded when I've seen them...

It's not as regular as you are making it out to be but still more often than it should but what can you do... let's not have StreetLites being taken off 1/5/5A/X1 to do X66/X67 as that doesn't solve issues, it just pushes the issue elsewhere.

Looking on BusTimes it has just been a really bad day at Darlington depot so allocations have been whatever has been available, seem to be short on full size singles at Darlington presently, the following weren't tracked on Bus Times today:
1590, 1591, 1606, 1612, 4649, 4651, 4658, 4804, some of which are long term VOR.

Things like the 12 now needing a full size single (primarily 1511) to meet school loadings also doesn't help.
