The frustrating thing is that it just needs extra rolling stock, nothing else, to solve the problem (the platforms at Oldfield Park and Keynsham are long enough for 5 carriage trains at least, probably more). The overcrowding has been there for at least 15 years, probably more, and led to a fare strike about 9 years ago to protest at this. At that time GWR▸ did lengthen a few trains I believe, but that didn't last long and we've been back to 2 carriage trains for most services. I'm well aware of the issues about ordering extra rolling stock, but it should have happened by now and it seems there is no prospect in sight for it to happen.
I recall an order for 10 x 4 car class 172 trains for Cardiff / Portsmouth that would have been running by now if they hadn't been cancelled because electrification was a better alternative. That would have releasesed 12 x 2 car class 158 trains sorely needed for other services in the Bristol and Devon / Exeter areas.
I recall loco hauled trains (old but loved) running from Cardiff to Taunton, but for some reason I forget, when something extra was cascaded (150/1s?) they were replaced not enhanced
I recall that electrification to places such as Oxford, Henley, Swansea and Bristol was going to release lots of units (and indeed many will still be released due to bi-modes) but the time scale 'promised' for that seems to have fallen back rather since last year's general election.
There is a need to keep the capacity issues on the radar of those decision makers who don't live in the area and use them on a regular basis. From an accountant's viewpoint it's easy to divide ticket sales by seats and come up with quite low percentages. And it's also rather easy to divide the cost of an extra carriage by the time in each day that it's "really needed" and find that you need to take an extra £25 per minute in fares for that busy stretch to pay for it.
A rather negative answer confirming your despair there. We are getting closer to cascades, and there are some radical things that could be done. Making all into
IEPs▸ could be considered radical and has been done. Re-arranging off peak and super off peak at weekends (as
SWT▸ are doing) could help balance the Saturday and Sunday loading and provide increased revenue at the weekend when the trains are getting equally busy. D trains with substantially more carriages than the trains they're replacing could perhaps be quickly drafted in onto certain lines, releasing current stock. I've heard mention of attaching locomotives to withdrawn electric multiple units, for example - and that has been done with some success on preserved lines, hasn't it?
Realistically, I don't know what the answer is. One positive route is to ensure that our elected representatives are well informed and know and echo the strength of view, and that views are expressed to support practical ways of doing things and letting it be known that compromises - such as replacing something with something just as old or even older - but longer and more frequent - IS acceptable!
And as I've explained before, the official statistics for users of the station bear no reality to the actual number of users.
Indeed - I 'shorthanded' what I wrote for "ticket sales figures". Even away from group station issues (Dorchester, Dorking, Tyndrum, etc) and line rovers which make a real mess on the St Ives brach, they can be way out in either direction from passenger numbers joining / leaving trains - both us and down. What they do indicate unless there's a change in ticket regime is a trend.
