Drivers based at Ashington can pretty much do anything, but i do believe there is a split rota setup at Ashington, which means depending on which rota you are on, you work either out of Ashington Town Centre or you work out of Morpeth (the latter being the express stuff X14/15/18 and Ser 2 and the former being the X20/21/22/1/35 etc).

Might be a little bit more complicated than that in practice, but generally that's how it works.
