I'm guessing that the X93 Middlesbrough-Scarborough service, given the route over which it operates, must be hailed as one of Arriva's sucsess stories ? I'm remember, and yes we are going back a few (?) years here, when it was a twice, possibily 3 times, a say service, operated from Loftus depot as a then extension of what, to the best of my recall, was service 58. It was generally operated by BU's, possible those so converted to be dual purpose.  The service has now gone through a variety of "upgrades" and operators with the inevitable spread of vehicle types. Now after a few, shall I say troubled, years, during which passenger numbers despite the problems, have increased immensely and clearly justified the investment in the BTL9's. Maybe I'm in the wrong thread to be asking for peoples thoughts, comments and possibily memories.
