On a slightly related note, it'd be good to reopen the station at Pontrilas, roughly halfway between Abergavenny and Hereford. Much of the infrastructure is still there including a freight siding. There's a local campaign and it's often mentioned as an aspiration by the Herefordshire rail groups.
Obviously it's not near Brecon but it's on a long section of line without any stations.
Looking at a map, Pontrilas looks a lot smaller than Caerleon and that doesn't have a station either (I think both are probably on Railfuture's list though). There's a proposal for 3tph between Cardiff/Newport and Abergavenny I beleive, which would provide a service that could serve Caerleon if reopenned without slowing the existing services. Personally though, I think the 3rd train per hour should be extended to Hereford, where there are more onward connections (Cotswolds and Birmingham) and would also allow that stopper to serve a Pontrilas station if there's a strong case for it.
The problem would be connecting up with the line @ Merthyr Tydfil
You're right. I think that any solution would be very expensive!
I don't think the Brecon-Merthyr line of old, which I think is the route partly taken by the Brecon mountain railway, would have any merit in today's world, just too indirect. I'm not sure what the maximum gradient an EMU can cope with is, or how to accurately estimate gradients with Google Earth, but I think the only way to make a new line competitive would be for it to follow the same valley as the A470. Trains to Brecon I expect would either have to bypass Merthyr Tydfil station or reverse there. I have plotted the idea, very roughly, on my
Wales new route map. I agree that it would be
eyewateringly expensive and therefore probably a non-starter though. That's one of the reasons why the whole route is in red on the map, unlike the other three routes on my map which are plotted in much more detail.
a first stage would be to put in decent "semi-fast" bus links in - Carmarthen - Aberystwyth is pretty good I gather. One of the franchise bidders proposed (pre Arriva) a comprehensive all Wales feeder network - but it came to nothing.
The Carmarthen-Aberystwyth bus timetable looks pretty good, but the single route number (T1) is applied to five different routes (though only two of those are regular, roughly every 2hrs making up an hourly service). What's the point of a route number if all the different routes use the same number? It's the same story on the three routes between Cardigan and Aberystwyth, all labeled 'X50' now. Also, I think long-distance passengers are likely to find the vehicles First provide for the Carmarthen-Aberystwyth services disapointing (although I've only used them for short hops of a few minutes within Aberystwyth, so cannot really provide an informed opinion yet, I must get round to a longer trip at some point). As for franchise bidders, I once read on this forum that one of the bidders (I think it was even Arriva) proposed reopening the Bangor-Caernarfon link. Then the powers that be decided to 'no-growth' the franchise and all the improvements died. I wonder what else we've missed out on.
The T4 Traws Cymru bus route from Cardiff to Newtown is hourly to Brecon via Pontypridd and Merthyr but only 8 a day north of Brecon, the last departure from Merthyr for Newtown is 1520!
New Adventure Travel run the X63/63 Swansea - Ystradgynlais - Brecon service which every 2 hours/90 minutes.
I agree the T4 needs improving particulary an later service from Cardiff at around 1635 which gets into Newtown at around 8pm.
Hours of operation are pretty much the only problem I can see with the Carmarthen-Aberystwyth timetable too. I think the first bus from Aberystwyth should be about 30mins earlier so it reaches Carmarthen at around 08:30 instead of 9am. Also, the last northbound journey being at 19:10 is around an hour too soon I think. As for the T4, the last southbound service from Aberystwyth to Cardigan doesn't get in until 22:36 so if a 16:35 from Cardiff would reach Newtown at 8pm I think the T4 ought to be able to have the last through service leave Cardiff at 18:35 reaching Newtown at 10pm. I guess the problem is Stagecoach don't have any vehicles or staff based in Newtown. On a route that long I really think there ought to be the capability to have vehicle and driver diagrams start and finish at the extremities of the route.
