Absolutely correct. You could almost say that those living in those hydrologically ideal areas were merely unfortunate victims of industrialisation and you'd be right in that, too. It just so happened that it was rural, largely Welsh-speaking Wales which was in the "right place at the right...

It certainly wasn't perceived as anti-Welsh by the people who drew up the plans; they mostly didn't even consider that there might be a case to be made by those to be displaced and the Welsh didn't have any say in the matter. Would you say that the highland clearances were not "anti-Scottish"...

One of the reasons this has become quite the rallying call for the Welsh Nationalists is that it wasn't just a community which was destroyed, it was specifically a Welsh-speaking community. Welsh had been actively suppressed since at least the 19th century, with its use for official purposes...

Apologies if people have seen these before, but they show reasonably clearly what the "previous route" was - well, back in the 1950s or so, anyway! Five tracks to the Bay Station, and a route beyond to the Oval Basin (now Roald Dahl Plass). From the collections at the National Museum of Wales -...

I drive along a 30-ish mile stretch of the M4 to and from work three days a week. Barely a week goes by without some evidence of yet another accident on that short section, ranging from tyre marks left by someone not concentrating, to swirly skid marks probably from out-of-control trailers to...

Not sure about absolute reliability, or whether it's just that TfW are learning to manage the foibles - at the peak of the heat a few weeks ago, 769s on Rhymney seemed occasionally to be timetabled "fast" - skipping some stations, presumably to avoid overheating caused by lots of starts?

There is a Vulcan (also a Victor and a Valliant) at the RAF Cosford museum, quite impressive close-up. There is also a Vulcan outdoors at the Midland Air Museum, and the aircraft is often open for cockpit tours - or at least it was when we visited a few years ago. Impressively small crew area...

Our experience of London recently, with pre-existing Oysters was that the u16 visitor discount could be added by staff at certain stations, but they had to "do something clever" with the Oyster machine, and seemed to think they were doing us a favour and it wasn't the normal way of doing things...

So how come I find it - or something very similar - written down on the EV web pages of every manufacturer I've looked at?

Batteries are getting better and bigger and things are improving, but there are still some common cases where it's marginal. For example, my commute is a round 90 miles with about 70 miles of that at motorway speeds and no realistic prospect of charging at the "work" end. I don't work 5 days a...

According to this US government report, there could be as much as 20kg of Cobalt in a current technology 100kWh battery pack. That is obviously 1kg of Cobalt per 5kWh of Lithium battery so a typical mid-range EV with a 60kWh pack might have 12kg of Cobalt. That seems quite a lot, though as it's...

Could you expand on that, please? Apart from paint pigments and some specialised metal alloys, I only know about Cobalt being used in catalysts, and the whole point of a catalyst is that it isn't "consumed and emitted".

I've used NiMH rechargeables in Sennheiser EW G2, G3, G4 and XS2 (all analogue) handhelds and bodypacks for some years. They seem to last well - at least in our use-case, which admittedly isn't four hours of full-on musical, and for the less-used sets it is sometimes more convenient to fit...

Very small sample - I only had four, but it was at the same time as the Eneloops and they definitely haven't fared so well. I don't use 7DS any more - they started doing snoods and vaping kit and the "useful" stuff like the batteries started disappearing. Haven't looked recently, but you...

I started dabbling with rechargeable AA NiCd batteries when I had a handheld CB radio - it had space for (IIRC) 10 Alkaline batteries or 12 NiCd. Buying 12 650mAh NiCd batteries cost half as much as the (secondhand) handset, but given the rate the thing chewed through batteries (CB could pump...

I found that Wikipedia actually has a reasonable article on the subject (at least it looks that way to my untrained eye). There is a picture of an expansion joint too:

On a long run of CWR then, do they actually leave expansion gaps - maybe as some kind of "lapped" joint rather than a butt joint to remove some of the problems of the latter? (but I do miss the sound!) I suppose it's a balance then between "normal" and "exceptional" high (and low) temperatures...

Genuine question - how much was track buckling a problem in the days before continuously-welded track? I presume even welded track isn't really "continuous" and must have some expansion joints somewhere so if (as some predict) we are going to see more, hotter, summer days as global temperatures...

Short-sighted. Architectural trophy building (a hotel? really??) rather than real practicality. Not only do they appear to have abandoned the Newport link idea, they also appear to be building empty offices on the park & ride - with no obvious location for a new P&R, unless I've seriously...

Well, I'm going to have to do some more research then because I've just looked at this brochure by Viessmann and am somewhat confused by the terminology. In one part of the table it claims a COP of around 5:1 for heating with air at 7C and water at 35C, which seems very good, but in another part...
