Looks like the 63 in R&C and I've no idea what that is towards East Cleveland Hospital.
I assume the X3A as it terminates in Brotton (it was Skelton Asda, but I'm sure there was some funding to extend it). But the map doesn't show the X3A route.

Given the route via the coast road it looks like the X4, which does run fairly close to the hospital, but would make more sense to extend the X3A down to the hospital entrance.
