Totally spot on, could not have put it better myself.
I believe the start of the decline in the Monklands began in 1997 following Stagecoach's assualt in Glasgow, a few months after that began the depot in Airdrie closed along with some service cuts, then about a year later more service cuts when the Lanarkshire services were renumbered into the 2XX series, then a couple of years later more service cuts, to about what is left now, along with the closure of the bus station. First had to concentrate it's resources in Glasgow.
The McGill's cut backs, and also the closure of the depot in Barrhead, all seem to have occured following the begining of the implementation of the LEZ in Glasgow. Coincidence?
I do believe that people in the Monklands couldn't depend on buses before McGill's came along, and as much as they improved the network slightly, the damage had already been done years before and wasn't going to reverse, and by the looks of things is only going to get worse.
Can personally see Mcgills and First being fully of the monklands area within 3/4 years. The smaller companies seem to love operating there at the minute and it's turning into a stronghold for them
