Bobstar posted:This is interesting, but in a country this size couldn't a good, affordable high speed rail network effectively eliminate internal flights, with all the benefits that brings? It depends. Let's say we built a Shinkansen-quality line from London to Glasgow. To ensure the best speed, there's no stops along the way so you can stay cruising at 186 MPH all the way through. The train trip would still take 2 hours 10 minutes minimum, longer if the route was built so that there was other cities stopped at along the way. To compare to the schedules you get in Japan where they actually have these trains, and stops along the way, the Tokyo to Osaka route, which is 50 miles shorter than direct London-Glasgow, takes 2 hours 20 minutes. Flight London to Glasgow meanwhile is apparently 1 hour 10 minutes. And I'd have to think that if the for-profit private operators got to run the high speed trains, there's little chance of them costing less than the flight would. Whether they're full would not necessarily be a good way to judge use. As long as you schedule less seats available than there are people who want to get somewhere by train, you'll have fairly packed trains. Jonnty posted:I think the reason people focus on HSR in the US is because the suburban sprawl makes commuter rail in a lot of the country totally infeasible. Much easier to set yourself a relatively achievable goal like eliminating some domestic air travel than to attempt to challenge 50 years of received town planning wisdom. The ironic thing is that you also need dense or at least reasonably continuous and compact development for the high speed rail to work. When everyone's spread at all over it's inconvenient to go to the nearest high speed rail, and you need to build a lot more of it to get to all the various spread out places. Like again, to go back to Japan since they have the best system in place for it, notice the way the routes are laid out: It's mostly one continuous route following the most developed areas of the country, with a few branches here and there There's lots of missing connections, like how if you want to go from Nagano to Osaka, you have to go all the way to Tokyo and then back out. There's plenty of Japanese cities and towns that don't have access to the system without taking other transport.

Yeah, but flights are airport to airport rather than city to city. Frankly if I had guaranteed seats that extra hour would come out in the wash since you wouldn't need the detour, the turning up an hour before your departure etc etc. Anyway, I just booked a short notice ticket from Köbenhavns Lufthavn/Kastrup to Karlskrona C in the south of Sweden and two first class tickets come to £80 and two standard class tickets would come to £65. I am now thinking about my last short trip on East Midlands and the cost + lack of seat, then followed by the last time I had to take a short notice trip to Manchester and the cost for that...

Train: get on train, sit about, get off train. Slight exaggeration, but think you need to look up the generalised cost function.

Focusing on the time spent actually in the air is the big con perpetuated by the airlines to make people thinl flying is quick and not a ridiculous waste of time (and hugely environmentally damaging). Even if we were to operate a French style TGV station not actually in some of the cities, a 2hr 10 min train journey from London to Glasgow would be 2hours and 10 mins from London Euston to Glasgow Central since Tetmini usually are (and in these instances can be, though they'd need to build a new bridge over the Clyde since the slowest part of any journey into Central is that bit.) Even now, at about 4 hours 20 mins, that's only about an hour more than the time you would have to leave for taking a flight despite only 1 hour of that being in the air. From the centre of Glasgow to the Airport is 26 mins by bus. From Heathrow to Paddington is 22 mins. So far that's a 1 hour 58 minute journey. Add on an hour before the flight for check-in and 30 minutes after for baggage claim, that's 3 hours 28 minutes. Suddenly a 2 hour 10 minute train journey sounds like a better option, not least because time spent on a HS train is not necessarily time wasted like it usually is in airports or on flights: tables to work at, WiFi to use. I used to travel extensively in France and the Benelux countries and there's a reason its hard to buy flights from Paris to Amsterdam, Brussels or even Avignon (429 mi versus 402 mi, London to Glasgow): it's easier, cheaper, and better to go by train.

If you want to know how poo poo our transport system is: you can't even leave the country easily without using a car. Of the 19 UK airports listed by Wikipedia as airports of entry only the following have train connections: 1. Birmingham 2. London City 3. London Gatwick 4. London Heathrow 5. London Stansted 6. Manchester 7. Newcastle 8. Southampton I'm not counting Dyce (for Aberdeen), Rhoose (for Cardiff) or London Luton Parkway because, despite their proximity, for foot passengers they're loving useless, often being at the end of the runway or in a village that borders the airport, not at the terminal. What you'll notice is that fewer than half have proper train connections and outside of London (including Stansted) four airports have them. There are no train connections for international airports in the following constituent countries of the United Kingdom: Northern Ireland, Scotland, Wales. Not one of the four airports in Scotland (popn. 5 million) has a train connection. Need to fly from a Scottish airport? Hope you've got money for the cab fair.* This is loving ridiculous. * some buses are available dependant upon road works and whether FirstGroup and/or Stagecoach feel like it.

Just last week I had the pleasure of getting reacquainted with the UK train system and it was even more poo poo than I remember and I just need to rant. Arriva Trains from Crewe to Haverfordwest: a stretch that services Wales' major cities as well as a bunch of middle-of-nowhere stops (at least they felt that way to me, but I'm not so familiar with Wales). As I waited on the platform, I expected a decently sized train for this journey. I paid 37 glorious pounds for an advance ticket, which amounted to more than half half my one-way plane fare from Berlin to Manchester (with Lufthansa, not Ryanair). The train arrived and all my hopes of a comfortable journey were dashed as I realised that, apparently, two carriages are considered enough for this particular line, despite the fact that the amount of people waiting on the platform in Crewe alone could've easily filled one carriage. I was lucky enough to get a seat and eventually, after Cardiff, the crowd thinned out a little. It was, however, the least comfortable train journey I've ever taken because the air conditioner seemed to be stuck at a permanent, balmy 12 degrees Celsius. Shivering in my thick sweater, I watched people in the villages we drove by stroll around wearing t-shirts, shorts and sandals in blazing sunshine. This journey took more than 5 hours. On the way back it was the same: two old-rear end carriages, hugely overcrowded and cold enough that you could store your milk in the train for a week and it wouldn't go bad. Most people had to stand for the two hours to Cardiff, then it was decided that the train was terminating there and that everyone would have to step on a new train. Stepping out out of the train and into the rain felt like stepping into a cosy log cabin after a long day out in wintery Siberia. Seriously, I've travelled on trains in Thailand with better temperature regulation.

As a strapping 6 footer, obviously there was no room in regular seating for me to fit my legs, so I had to sit on one of the inward facing seats that sat over the diesel fume pumping hot air blowers. Which would still be switched on in the middle of summer. Air conditioning, luxury. At least you could breathe. *NB: since I quit commuting, they have now replaced the trains with lovely new air conditioned ones (read: 15 year old trains instead of 30)

Also Glasgow has either two or three bus routes, most of them adapted for large bits of luggage, that go from the City Centre to Glasgow International airport every 10 or 15 minutes, as well as the bus link from Paisley Gilmour Street (regular trains from Central) to Glasgow Airport which isn't far down the road from the station.

Luton also has a regular shuttle bus running from the station to the terminal.

Moving a discussion about disabled accessibility on the Tube from the Olympics thread to here as the better place for it.Install Gentoo posted:It is my understanding that there's a lot of stations that only take one kind of train, don't have wheelchair accessible route to the surface, but also have the platform not flush with the trains in use. Since there's already 33 stations that are equipped with an accessible route to the surface, narrow enough gaps, but incorrect platform heights. Apart from Westminster and the (outside the centre) Northern Line stations I mentioned i can't think of any stations that have step-free access to the platforms but don't have a step-free access to the train. (In fact ISTR there's a very good reason why sub-surface stock trains *must* have a step up and out even on completely straight platforms but i really can't remember it, perhaps someone can enlighten me...) Getting step-free access (or even escalator access) to a number of stations would be basically impossible, too - Victoria, Monument, Liverpool Street and Edgware Road D&C lines, Oxford Circus and Holborn on the Central immediately come to mind as stations with very very small surface buildings unsuitable for escalator or lifts and no free space for new buildings without massive expense. Also, unfortunately, the stations that most need improvement of access (the big interchanges like Waterloo, Bank/Monument, Victoria, and King Cross/St. Pancras) are also the hardest ones to do, and pretty much also have to be the first ones to do. There's not much point in sorting out, say, Angel and Stockwell Park if those end up the only two stations people can travel between.

goddamnedtwisto posted:Moving a discussion about disabled accessibility on the Tube from the Olympics thread to here as the better place for it. Ok, here, this is the map from TfL, which marks all stations that are "step-free" from street to platform: For each station, and each line at a station if neccesary, they mark off step height with Green being in the zone considered "no step", Yellow considered step, and Red considered a high step. Meanwhile, A is a gap that's considered short enough to roll across safely, B is less safe, and C is a severe gap. Additionally, when there's a circle, without a letter, but multiple colors, that indicates either transfer to another underground line's platform at that station is possible without steps, or transfer to a mainline/overground train station is possible from the platform without steps. Any station marked A and Green is considered fully accessible by TfL. Now besides those, there's 33 stations/parts of stations with accessible route to the surface, "A" rated gaps, but Yellow or Red step height from the platform. That is, these stations, for at least one line going through them, would become accessible by simply raising or possibly lowering platforms. In some cases you might add the access by only raising or lowering certain parts of the platform, with appropriate warning signage for them. And again, I'm not saying, "add new surface to platform access", I'm talking about "add train to platform access in stations that already have surface to platform".

I just had to queue for 40 minutes to buy a ticket at my local train station, and lots of people in the queue missed their trains or had to board without a ticket because they couldn't get one in time. I don't use the train regularly enough to know if this is a common occurrence or not. It appeared to me that the station was understaffed, but it may have been that this was just a one-off and generally staffing levels are okay. In any case, what was annoying was that all the people in the queue who were audibly grumbling were blaming the delay on British Rail - e.g. One guy said, 'this is typical of British Rail'. But it's not loving British Rail who runs the station, it's Greater Anglia, a privately owned, taxpayer subsidised rail franchise. Where I live is a solidly Tory area, and my impression of the people who were complaining was that they thought having to queue in that way was a manifestation of the failure of running the railways as a nationalised industry. Again, as I said, I don't think it's fair to draw any wider conclusions about rail privatisation from this episode, but it's incredibly frustrating that these people take being inconvenienced by a privately run company as evidence against rail nationalisation.

As an American I occasionally read this thread with morbid curiosity. As to the question raised a while ago about passenger rail in America, one of the problems is the FRA (Federal Railroad Administration) and their train strength requirements. From what I've heard on the issue, foreign (European and Asian) trains are safe because they have systems in place to not crash into each other. In America, trains are safe because we can full balls crash into a freight train and be OK. All this extra buff strength is expensive, both in initial capital costs, and in ongoing running expenses. When we built the Acela, only three companies even tried to bid because nobody wanted to double the weight of their rolling stock to sell it in America. So as the only country in the world (that I know of) with these kinds of buff strength requirements, we're essentially the only market in the world for these trains, and it's a pretty small market at that.

Well the issue is that the federal and state governments don't want to have to invest in the capital it is going to take build passenger only track like in Europe and Asia. American trains by and large have to be prepared for a dual use environment so usually are far heavier than other countries and our system is more expensive/less efficient because of that. I have heard they are loosening restrictions on transit services that doesn't actively use freight track. I am pretty sure Acela does at various points though.

You also have to realize that with all the already heavily built trains in passenger use, any lighter built stuff would have to be able to withstand collision with them! And that'd require being about the same strength as if they hit a freight. No system for preventing crashes is fool proof, so it's really important to mitigate the damage when crashes inevitably occur. Even if America stopped requiring trains be built as tough, you still couldn't use the new American trains in Europe - they're too wide for the loading gauge in many countries. With the Acela for example, it's an inch too wide and 4 inches too tall for the loading gauge along most of the French TGV system, and too wide for parts of Germany. And then you have the rail cars used for commuter rail systems , like this one currently being used across America and Canada http://en.wikipedia.org/wiki/Bombardier_MultiLevel_Coach which is 10 foot 10 inches wide. Apparently the only places in Europe that that will fit is Scandinavia, the Betuweroute, and the Channel Tunnel and its approaches. As far as being the only market here's also Canada and Mexico at the very least. And it's not actually a small market.

Um. Well I don't like bold claims, but we solved this in the UK by using something called TPWS (Train Protection and Warning System) whereby all stop signals are fitted with overspeed and overrun sensors that jam in the emergency brake as if the signal is at red, thus vastly lowering the consequences of a collision if it will occur. These days, the system is deemed so robust that it's practically impossible (without circumventing the system) on a modern TPWS design for two trains to actually collide.

There's still the potential for derailments and collision with stuff next to the tracks though isn't there? Of course, most collisions on American railroads involve some moron or their vehicle on the tracks where they shouldn't be. Did the TPWS rollout involve needing the existing trainsets in use needing to be modified or was it done in a way that "just worked" with everything that was already on the rails? Incidentally, systems like that are being tested or planned to be tested in some areas in the US where currently both freight and light rail passenger trains run on the same tracks, but are currently required to have time separated operations. Can't crash your lightweight light rail vehicles into a freight train when the light rail runs from 6 AM to 10 PM only, and the freights run from 10:30 PM to 5:30 AM only, hence they get a partial FRA waiver on crash standards.

It was a retrofit but was done incredibly rapidly (plus was cheaper than rolling out ATP everywhere) because it's just cut into the existing safety systems and just dumps the brake pipe. The UK also has a system called AWS which has been manditory since the 1950s I think on stock. It was initially fit to high risk signals, but now it's on basically all controlled signals as part of new schemes or mods. Work I'm doing currently we've got it practically everywhere and it provides totally robust protection against collisions. As for the stuff on the tracks argument, this is an interesting point about UK vs US railways, in that ours are totally surrounded by a boundary fence (which you can report if it's damaged and someone will be out to fix it pretty sharpish). Oddly, they were mandated not to keep people off the tracks, but to keep railway workers ON the tracks, and therefore not in the 5th Duke of Devonshires back garden. British class system strikes again! edit: the Wikipedia article is pretty good http://en.wikipedia.org/wiki/Train_Protection_%26_Warning_System but a bit out of date to current practice Bozza fucked around with this message at 20:11 on Sep 5, 2012 |
