It is a fact that our X93 has grown and grown over the past decade, and dare I say decades? I show my age when I remember it being something like a twice a day extension of the Middlesbrough - Lingdale service operated by United and crewed from the late Loftus depot. Now it appears as one of Arriva's flagship services but how it will develop from here is a difficult call as matching revenue against investment should yield an answer; but then as we know, revenue on the route is very seasonal and to an extent, dependant on the weather.
The X4/4, again an Arriva success, is so different, encompassing not only the seasonal trade but also the communting/shopping revenue gleaned from its Middlesbrough-Redcar-Loftus section. I've not heard what loadings are like on these services lately but wasn't there once talk of increasing the frequency.
