I’m curious, what is the incentive for bus companies to compete against each other?
There’s very little competition nowadays, so I’m sure the operators would be keen to find out what they’re missing.
On large bus corridors (usually areas of high deprivation with little access to rail transport) such as Paisley Road West, QEUH-Govan-Glasgow, Easterhouse-Glasgow, Cumbernauld-Glasgow and Shawlands Cross-Glasgow, the incentive to compete is obvious - there are a lot of passengers, enough that running a competing reliable service with slightly cheaper fares may be able to turn a profit. If a company then eventually "wins", fares can then go back up again.
If operators are 'competing' and there is an 'overabundance of provision' in this one area, why is SPT using taxpayers money to fund the 153 which spends 2/3rds of it's journey time plodding along Paisley Road West? Or is this just yet another great example of SPT wasting money because it is beyond their basic capabilities to properly plan and run the tendered bus network?
If so, can you explain why you expect this to change with franchising when there is a clear pattern of mismanagement of public funds and general inability to do basic things?
The 153 is an interesting situation: whilst the obvious solution is to pay First Glasgow to amend the evening and Sunday 10 to go via the 153 routing in Pollok, First do not tend to accept SPT tenders (the only one I can see is certain evening runs on route 8). You could choose instead to tender for an evening X8 service, but you may understandably receive complaints from First and McGill's that you are effectively subsidising an unsustainable competitor to a set of commercial evening Glasgow-nr Silverburn routes.
For social reasons, you would prefer the route to link directly to Glasgow as dropping potentially vulnerable passengers at Cessnock at nightime would lead to less people wanting to use the service, increasing subsidy cost - plus, I would wager it also is likely the preference of the local authority, Glasgow City Council. Furthermore, having the service run direct at night means vulnerable people (e.g. women) leaving a Glasgow/Paisley Road pub can get as close to their house in Pollok as possible without having to spend around 10-20 minutes in Cessnock hoping they don't get robbed, assaulted or worse.
