Well, we all know the tricks to make something seem worse than it is to cut it.
Run a bad service, people stop using it, then argue that nobody uses it and axe it.
That's why the council should have control of all routes, and have to approve new ones. If a private operator suggests a route, that's fine - but perhaps it should still be put out to tender and only allowed if the council now adds it to the timetable, so to speak.
At the moment the council subsidises some routes completely, or in part. In theory, private companies can then compete to provide an amazing service on the profitable routes - except that often ends up in disaster for a number of reasons.
That sort of competition doesn't really help, as the operators only want to put the other ones out of business (or give up a route) to be able to put prices up again - at least most of the time.
In London, you may have different routes, but not multiple operators covering the exact same route. I don't see why Arriva, First, Stagecoach, Uno or whoever can all run routes competing with each other, such that passengers have buses turning up every 5 seconds, then leave loads of other areas without a bus service at all.
There are parts of London that run buses that aren't busy at all, but it's a public service and we've already concluded that people only use a bus to go somewhere if they know they can come back!
One thing I'd like to know is if these cuts are temporary, and they'll be reinstated when the economy recovers. I could accept the hardship for a year or two if I knew they'd revert back to before afterwards - but I just know that many cut services will never return.
