Also, the X61 Blackpool to Manchester is long gone - although if memory serves did disappear after ENCTS was introduced in 2008. If we are going back into history, maybe a better example would have been the 400/401 "Trans Lancs" Expresses destroyed by the completion of the M60. The section norh of Ashton (400 at least) is still covered by at least 6 stopping buses an hour, but Ashton to Denton has been reduced recently, and Denton to Stockport is just a joke with just one bus an hour (was four by different routes at one point).
Just as an aside, I the BIB points out the relative bouancy of GM's bus network if there's only 1 Stagecoach route quiet enough to warrant single deckers.
I think the X61 lasted as long as 2011, certainly it was around when I moved to Manchester in 2010. Enough time for ENCTS to have an impact and arguably the single biggest change to a service which had otherwise been successful for over 50 years.
