A woman from Greater Anglia jumped aboard the train while it was sat at the terminus and asked if I could complete a quick survey. I agreed, since I wasn't going anywhere soon. One of the questions was: "Would you recommend this train company to any of your friends who were thinking about travelling?" Rather than what? Walking?

So you think the BBC shouldn't look into things and should just accept "common knowledge"? The general public's perception of price rises are almost always without consideration of inflation, like the whole "Freddos aren't 10p anymore!?!?!" thing; while since the time Freddos were priced at 10p there has been almost 100% inflation, so they are now 20p. The BBC article points out that several rail routes and ticket types have not increased equal to inflation, even though the general trend is that rail prices have increased more than inflation. twoot fucked around with this message at 02:11 on Jan 24, 2013 |

I wasn't aware that the average inflation rate of the last 5 years was 20%. At an average rate of closer to the CPI 3% it would take over 33 years for inflation alone to be the cause of the doubling in price of Freddos. And since Freddos were not available between 1979 and 1994, that's clearly not the case.

I know there's maglev and all, but that seems like a dead end because of infrastructure costs. They would be really really bad for the environment as well, those 8 ton batteries will need replacing all the time (the savings on fossil fuels will also prob be negative once you include the manufacturing costs of the battery). Electrification makes much more sense in the long term. e: I'm not sure how much improvement is rail efficiency is physically possible, it is already ridiculously efficient. Going faster without using more energy will always have large infrastructure costs, and pouring concrete is very carbon intensive. I suppose the "next-gen" technology is really in reducing costs and improving design and town planning so that more people will travel by rail. There are also gains to be made in timetabling/organizational structure/signalling in order to get more tph on limited track space. None of them are very sexy though.

Weembles posted:What prevents them from running for longer than 30 minutes on third rail power? They're simply not designed for it. I'm no mechanic so I can't tell you why but they're rated to only remain moving on third rail power for about 30 minutes; which is more than enough time to move them out of the NYC train tunnels where running a diesel engine is banned except in case of emergency or repair works with passenger service shut down. The other two designs can run on either power mode as much as they want however.

At a guess when you have a primarily diesel locomotive, you would be likely to use a naive design where you have separate 'throttles' (since you usually control the power to the bogie motors by varying the speed into the generator on a diesel locomotive which in turn adjusts the voltage/current dependant on load, but have a constant voltage source on an electric locomotive, which means using rheostats or such to control the voltage to the motors). As such, if your design is only for short use of electric, then you can avoid a lot of the heatsinks necessary to dissipate the heat from the rheostats and just rely on it not getting 'that hot' if it's only running for 30 minutes max. OTOH, a locomotive that is more evenly split between methods of propulsion, you'll need to dissipate the heat generated from a potentially constant use of the electric pickup, and thus need to cart around the heatsinks anyway, and can use a more complex single throttle system, that makes the diesel/generator act more like a constant voltage source.

The phone-based ticketing system works well and there are dozens of ticket machines at the stations, one breaking doesn't prevent anyone from getting anywhere. Even if they all broke, the stories of people invalidating their tickets by pen and then getting fined by the conductor is a bit silly too. If you board the train and the first thing you do is explain to the conductor what has happened, they're more than happy to invalidate the ticket themselves. It's only if you take the piss and wait a few stops that they'll shaft you. Swiss trains are thoroughly awesome: They're dirt cheap if you have a 1/2 tarif card which everyone except tourists have, a bit like oyster in london. They're spacious, clean, efficient and frequent. The complaints are just because the swiss don't like change (or immigrants, or poor people, or liberals).

Although in Scotland even if the machine's working you can buy one on the train, it only really matters if there's a ticket office that's open.

It's only if you take the piss and wait a few stops that they'll shaft you. Genuinely don't understand - hows it remotely cheeky to wait for them to come to you, I'd think it a bit weird to go bounding up to them at the start of a journey saying I bought it on my phone instead of on the platform or whatever, especially if that's offered as an alternative. Although I suppose it's not surprising that a "Revenue Protection Inspector" or what have you would consider it cheeky not to run up to them immediately and beg forgiveness.

In tangentially train related news, I got through to The Chain on Radcliffe and Maconie today on 6 Music, and ended up chatting about HS2 for a bit! Obviously, this doesn't have a lot to add to this thread, but I was so excited I'm basically telling everyone. I was on at about 2:15ish (so and hour and a quarter in). re electrification / batteries etc, other than making my media debut, I've been super busy today. New project ahoy! Watch out Liverpool Lime Street, I'm coming for you...

Wootcannon posted:Bozza - I take it this essay is going to go the way of the level-crossing post :p It's a little different to the UK, and hence the confusion. In Switzerland (and in some other EU countries, Italy for example), the onus is on you to ensure that you have a valid ticket the moment you step onto the train. If you don't, you shouldn't be on there. If it's a genuine fault you're expected to tell the conductor immediately, and he/she is waiting outside the train from the moment the doors are open until they close. While the culture in the UK is that the conductor is a service rep there to do your legwork, in Switzerland it's a different matter. The phone problem I agree is a different story- that person had no reason to believe that they were travelling without a valid ticket. The case I'm referring to is the people who board with an unfranked ticket. I've done it a couple of times, once when the train was seconds from leaving and I didn't have time to stamp it, and once when the machine was broken. On both cases finding the conductor meant I didn't get a fine.

Dual mode trains are probably going to get rolled out as part of the intercity express programme so that trains can, say, run to Edinburgh on electricity and then up to Inverness on diesel. The problem with dual mode is that when you're under wires, you're dragging round a heavy diesel engine and fuel tank that isn't doing anything except wearing out the track and taking energy to accelerate. This would be even worse with batteries, their energy density is around 1/30 of that of diesel. If we're going to store energy on board, this way would be much more fun http://en.wikipedia.org/wiki/Gyrobus
