I once worked on a development where the council suggested extending a bus route to serve it. Which is a reasonable suggestion in the right circumstances. However this was far from the right circumstances, add it was a large site and would have been a long and winding route compared to the road route.
As such we came up with a solution which extended a route from the far side of town, went past the Hospital and was much more direct. The local bus company liked it so much that they helped by producing bus maids and timetables for us to use in our planning application for free! Personally I think they could see how much of a disaster the first option would be, whilst the latter would be sustainable and they would l output be able to run it on a commercial basis, quite possibly from nearly day one (due to the link between the far side of town and the hospital).
Sometimes people get ideas in their heads and run with it, now the idea may not be terrible in the right situation, however in this situation it wasn't the right thing to do.
What SWT/SWR needs isn't tweets to services it needs some serious infrastructure investment (probably about 10 years ago and a larger nunnery if 444's and 450's when they were ordered). Things like Crossrail 2, Woking junction, Basingstoke junction, Southern Approach to Heathrow, third rail to OHLE conversation, etc. It's been treated as the cash cow of the industry, when with more investment it could have generated even more income.
Such decisions least to the solutions like those currently resulting in failure. Including the user of the 442's and the lack of power available on the network.
