Around 100 vehicles were used for the Newcastle to Sunderland trip in the morning in 4 convoys. However less were used in the return journey with only being 3 convoys and less coaches used. I will post a list of my sightings for anyone interested later on.

Just did a quick check and the vehicle count is...
105 vehicles used on the outbound run from Newcastle to Sunderland.
20 vehicles used to transport Sunderland fan clubs from various areas (some from Cumbria, Yorkshire and Manchester).
10 vehicles used on the Sunderland AFC Park and Ride from Sunderland Riverside Park to Stadium of Light.
2 vehicles used by Newcastle United as Team Coaches.

Actual list of vehicles to follow once I fine tuned it.
105 Toon Fan Vehicles
20 Scum Fan Vehicles
10 Scum P&R Vehicles
2 Toon Team Vehicles.
