Did 2009 ever operate in Derry, to anybody's knowledge, albeit for only a few days back in 1997? I recall before the Ultra's started in service proper, a Citybus one(2700??) with digital display operated in Derry to get drivers used to them. It only ever displayed "City Centre" and had livery somthing along the lines of "The next generation of low floor Citybus" Then I recall another low floor(of sorts- I can't remember) which was in Citybus livery, it did not have a digital destination, but it did have numbers but no blind, could this have been 2009 in 1997 for about a week??
