The 36 can very easily get full, especially between Billingham and Teesside Park.Same with some journeys on the 37 38 and 59 as well. I think certain journeys on the 39 get quite full as well and I have seen a 13 quite full before as well.
One is often utilised on service 35 which I think gets busy on journeys round school times, there's also a Sedgefield Community College contract from Wynyard which requires a double decker.
