Wonder if the reason for the switch from EcoCity's on the Sunday 5A's is because of either the EcoCity's possibly being a bit large to get round the 3 route or possibly because the 3 and 5A now operate on a Sunday night using the same buses as it does during the daytime, could imagine it to be a bit of a faff switching the EcoCity's with Solo's for the evening runs.
Speaking of the new evening 5A between Darlington and Newton Aycliffe, here is 2858 on the first Darlington - Aycliffe Sunday evening run earlier.
