I think that's a bit of a harsh response. A 125 mph electric unit train is not exactly the innovation the HST was in its time. 125 mph in the UK? No. 125 mph diesel anywhere? No. Intercity unit train in the UK? Not much before the HST. Now compare the IET. Apart from being bi-mode what does it do a Pendolono doesn't? Apart from not tilting? OK the bi-mode bit is more novel but doesn't excuse reservation systems that don't work or toilet doors that fail when the train isn't level. I think the problem is not the novelty but because trains are just so much more complex these days. 3 Link to post Share on other sites More sharing options...
Zomboid Posted August 27, 2019 Share Posted August 27, 2019 You can't achieve much of what an 800 does if you use "proven technology" from the past. So the fact that Hitachi have been making trains for 100 years isn't really relevant. There's clearly the usual niggles that you get with new trains, and they're different in nature to what has happened before. I suspect there's actually a lot of innovation in there, but most of it will not be obvious to anyone other than Hitachi. 1 Link to post Share on other sites More sharing options...
RMweb Gold rodent279 Posted August 27, 2019 RMweb Gold Share Posted August 27, 2019 And I don't think we can down play too much the "dead hand" of the DfT in much of the IET/IEP specs. I suspect if GWR & LNER (and it's predecessors) and other interested parties had been left to their own devices, and maybe collaborated, on the IEP, the rolling stock may have turned out differently. 3 Link to post Share on other sites More sharing options...

Not sure what kind of innovation is left for new trains: Maglev - Done, Monorail - Done, Tilting - Done, Bi-mode - Done. And while the HST was, and still, is a magnificent train, was it really that much of an innovation over say the Blue Pullman, or the Edinburgh/Glasgow push-pulls, simply having more power to go faster ? 1 Link to post Share on other sites More sharing options...
lmsforever Posted August 27, 2019 Share Posted August 27, 2019 A question for Royal Oak is there a marked difference between driving an HST and an 800 ie is the 800 a more relaxed drive etc and do you like the 800? Link to post Share on other sites More sharing options...

I suspect there's actually a lot of innovation in there, but most of it will not be obvious to anyone other than Hitachi. Genuine question. Apart from being a bi-mode, what does an IET do that couldn't be achieved with proven technology? It really isn't obvious to me. If, for example, the reservation system linked to wifi, or had seat sensors, or en-route updates, I can see why it might take a while to get working. But - while it's a really nice implementation, I can't see what's so novel about it that has required well over a year for it to work properly. 2 Link to post Share on other sites More sharing options...

I'm not saying the IET should be innovative. As for the HST, I'd say the innovation was putting together existing ideas to make something that was novel. And very successful. But it still was faster than anything in service before and could perhaps be excused some teething problems. 1 1 Link to post Share on other sites More sharing options...

However some of the 'teething problems' such as the cooler group in particular and various troubles with the engines ought really not to be excused. But in terms of passenger amenities they were a big step forward even if they were unreliable for sometime, especially in hot weather. Link to post Share on other sites More sharing options...

Each element is nothing especially new in itself AFAIK, but the integrated package is something that's never been done before. It's always the interfaces where things fall over. I was really thinking of things like the acceleration (notwithstanding the lack of installed power on diesel), reliable and effective AC and so on which you'd never have achieved using 30 year old tech. Even in things like electrical efficiency - a class 91 is a highly reactive load on the power supply, which is much less efficient than modern variable frequency drives, where reactance is very low. 1 1 Link to post Share on other sites More sharing options...

I wonder how many football pitch or Olympic swimming pool lengths that equals? A 10 coach Class 800 is roughly 260m long (26m per coach I believe) Very roughly 2 to 3 football pitches (a pitch may be 100yds to 130yds long). And roughly 5.2 Olympic Swimming Pool lengths (50m, 164' long or 53.66 yds). Link to post Share on other sites More sharing options...
