The X21 will hopefully get passengers from Station Town and Wingate like the Go North East X7 does and hopefully further afield like Darlington, Aycliffe, Sedgefield and Trimdon.
I am hopeful that this service will be a success as I'd like having a direct service to Sunderland again as I hate changing buses in Durham or Peterlee bus stations.
Part of the reason why I think the GNE X7 is so good is passengers connecting from their East Durham services although I think it is also busy because they only have 1 bus an hour between Peterlee and Sunderland while Arriva have 4.
The loads on the 23/24 are usually better coming into Sunderland because concession pass holders will just on the first bus that turns up.
