Think the 14 is largely commercial
It is - the section beyond Cannington to Williton was supported. So what's left is the commercial part. There's around 2/3 buses worth of work there adding in the B1 and the need for meal break cover. I guess you could design a timetable for the 14 which incorporated a meal break in the middle of the day but it'd make for a long day's work with an additional hour positioning from Taunton at the start/end of the day.
The B1 could have used these 'spare' Minehead buses in between college times to beef up the frequency but First have never done this, the double deckers simply sit idle in between. I notice the current version of the B1 timetable just serves Rhode Lane - Taunton Road - Sydenham and the Durleigh part which was B2 is now part of the 14 again. Previously the timetable didn't even co-ordinate the journeys to offer a 30 minute service over the common section. It wasn't too hard for me to devise a timetable which did just that....! No additional buses/drivers required, just an application of some common sense.
But no, we have an hourly town service that's impossible to use, and easier to withdraw through stated 'lack of use'. Well, if you miss a journey you're hardly going to sit around another hour for the next one? Sad to see when it could have been so much better. First managed to see off Webberbus who intended for them to close Bridgwater depot, running around 10 additional buses with their costs for a few years to achieve it but they've managed to close it themselves without outside help.
Bridgwater might be a small uneconomic depot, but that's down the choices First have made. It has a proud, small team of people working in it. There are historic tensions between Bridgwater, Taunton and Yeovil and Taunton has always been the dominant depot of the three, always having the best of the buses. I suspect most Bridgwater drivers won't transfer to Taunton to help the 'takeover'.
