I'm unsure on the PVR of the X30/X31, I think it might be 5.

But if you work out the length (in time) of the route from Newcastle to Lanchester, and back, you can divide the total time up by 30 (the frequency) to find out how many vehicles are required.

Stanley to Newcastle is roughly 40 minutes, and I think it's something like 30 to Lanchester, so a full run from A to B may be around 70 minutes...70+70 comes to 140. Round it up to include turn-around times, you get 150. 150 divided by 30 = 5.
