Which, really, is the way to solve this whole rediculous problem of millions of people sitting on trains and in cars every day - get as many people whose jobs permit working out of their houses - or in small satellite offices dotted around. It's the way forward. Then the people whose presence is actually required will have an easier time of it too. This is the sort of thing that will not happen by itself - it needs some incentive, such as taxing the hell out of city premises or something. But that won't happen... Removing subsidy from commuter services would do it. they are the services that are NOT subsidised, in the main. |

There was a manual ring for the conductor to pull to move the "points" *on most junctions. The old trollybusses in Riga (1997) were even simpler: Flexible cable from each pole ran down to a sping loaded retractor spool on the back of the bus (think hoover cable rewind). To move the pole, conductor pulled on the wire. Very simple There was some sort of hook on the pole and the vehicle which could be used to latch the pole down to if required. And the trams in Riga have properly designed track loops at route ends. Why? The driver just walked up to the other end in our trams? The brand new trams they have in Geneva drive one way only and only have doors on one side. So at each end they have to go round a large space-consuming loop.

Road freight is at least 80% of the total. Our rail network strains to take the other 20%. To make much difference you'd have to make that 60/40, that is at least a doubling of the amount of freight on the railway. Could you kindly indicate which lines you think it's gonna be on? Why do you think I was suggesting going to four tracks as much as possible? That way the slow freight could mix with the slow local trains. Freight often runs overnight. As you'd see if you catch any late trains round London. And that could likely be increased. 20% may not sound like much, but putting that 20% on the roads cause chaos. That 20% is already on the roads. Could you explain the maths to me? I'm not talking about putting an extra 20% on the roads, I'm talking about taking 20% *off* the roads. So on the roads, you've gone from 80% to 60%, a reduction of a quarter. Not massive but would probably help congestion a lot. But to achieve that you've gone from 20% on the railway to 40%, i.e., a doubling. I'm asking how that might be achieved. But if most freight already runs overnight, there's a lot to be said for adding the extra tracks so more of it can runs daytime too. Adding track is pretty expensive. If not it would already have been done to reduce passenger overcrowding. But I don't think overnight freight capacity is anywhere near maximum. If you don't build HS2 you've suddenly got a ****ing great big pot of dosh. Virtual pot. It's all borrowed, or would be. -- hugh |

The actual loss in net income from a 30K+ job in the city was less than 10k net. I have at least two other friends who work as subcontractors entirely from home. It will happen because its cheaper. What is needed is for crap managers who cant manage except by holding meetings and waffling to be sacked, and crap businesses to fold. And thats were the "fault" lies. They don't like being out of control of their workforce and all seem to think that as their working from home they'll simply skive all day.. This must change 'tho I don't think taxation is the right way to go about it. I've worked from home for years now and its bliss, no poxy rush hour traffic queues...... -- Tony Sayer |

Of course they would ruin it by covering it with solar panels, but
that's the stupidity of Cambridge. The real stupidity was developing the town centre with large shopping centres. It should have been left what its best at a pedestrianised small medieval town centre and then they ought to have had a decent ring road system with the shopping etc out on that... 1) Was that how it was in Petty Cury previously? Before my time there if so. There is the Loin yard and they've added the Grange Arcade and over the other side of town the Grafton centre... 2) They seem to be trying to do that on the Newmarket Road but good luck travelling on *that* road in rush hour. Newmarket road is screwed at almost -any- time of day now... -- Tony Sayer |

But to achieve that you've gone from 20% on the railway to 40%, i.e., a doubling. I'm asking how that might be achieved. It only takes a small percentage reduction in road traffic to make a big difference to the traffic flow. School holidays are a good example. And a small increase over normal can clog things up totally. As we will find during the Olympics... But if most freight already runs overnight, there's a lot to be said for adding the extra tracks so more of it can runs daytime too. Adding track is pretty expensive. If not it would already have been done to reduce passenger overcrowding. But I don't think overnight freight capacity is anywhere near maximum. If you don't build HS2 you've suddenly got a ****ing great big pot of dosh. Indeed. If it ever gets built they'll go for airline security so check in etc takes several times as long as the actual journey. -- *A picture may be worth a thousand words, but it uses up a thousand times more memory.

We can get a limited range of BETTER veg at the village shop..at vastly lower overall prices.When diesel costs are factored in. The difference is that those who ARE already commuting might as WELL use the supermarket since the journey is paid for already. Round here we have a lot of locals and work from homers or off for 6 weeks touring' etc etc etc. The difference is between 'dormitory villages' and 'real villages' The real ones tend to actually have shops and facilities that people use.. |

Rail can do all the long distance stuff and then freight taken in smaller trucks to local destinations. In a perfect world, yes. In this one, the cost (Money, and probably fuel as well) of taking stuff off a lorry and putting it onto a train, then doing the same in reverse is a lot more than just leaving it on a lorry, and letting the lorry do the whole journey. Although Eddie Stobart transport do put a lot of traffic for Tesco and Coca Cola on their link from Scotland to Daventry, with one train journey replacing a couple of dozen lorries. According to Wikipedia, the rail service is subsidised, while the lorries aren't, otherwise it wouldn't make sense to run the trains. Rail is perfect for taking bulk stuff like coal from source to destination on a fixed route. It used to be reasonable for carrying small consignments on busy routes from station to station, until most of the freight facilities were closed. Even when I worked for British Rail in the early '70s, it was quicker and cheaper to send a lorry full of stuff by road than to send a wagonload from Liverpool to London. One day, rather than three or four, if the wagon didn't get lost. On the other hand, sending five thousand tons of coal a day on a dozen trains from a pit in Stoke-on-Trent to half a dozen power stations was a doddle. -- Tciao for Now! John. |

The Savings you achieve depend entirely on the relative price yo are paying for diesel and LPG. They are not LPG conversions in the way that a petrol engine is converted, they introduce the propane into the air intake and fool the ecu into reducing the amount of diesel needed. We played around with it - and blew up the engine in the process. You could achieve some quite good performance results if you put in enough propane and ignored the emission and efficiency.

The pious is supposed to usee the battery to get up to speed and the engine at peak eff to stay there on motorways. Sadly the engine is no better than any other engine at that optimal speed and having to carry around all the storage is juts extra weight. Its precisely the same as having windmills on the grid..and using a gas engine to balance them. Nearly all the gains are wiped out by the needful fluctuations in the gas engine, and the net result is cumbersome and expensive and ultimately not advantageous |

"O" level economics, but it's hardly rocket science to work out costs from published tariffs, even ignoring the massive subsidy that rail got and still gets. Stobart's rail link from Scotland to Daventry is subsidised by about £400,000 per year, from what I've read about it. And the Daily Mail still has some of the best cartoon strips you'll see, even if they did stop running Peanuts. Worth the 50p a day, even if you don't read the news in it. -- Tciao for Now! John.

Exceed the power it produces at that and it becomes horribly inefficient. Drive slowly and with economy in mind and it can produce quite good results. As, of course, can most other cars of that size. Load it up and drive it a bit harder - like keeping up with the traffic on a motorway hill - and it becomes far less economical than a conventional car. As well as being a pain in the arse to drive. You are missing the whole point. It is not a plug in hybrid in the previous sense. No I'm not. If you run an engine at a steady speed it produces a given maximum amount of power. That can either be used to charge a battery or drive the vehicle direct. If it is set to provide the maximum power required for driving the vehicle direct, it will be horribly inefficient when that maximum power isn't needed, if the battery is full. The engine is not mechanically connected to the drive train. It's like an electric car but you carry round a petrol generator to charge the battery when required. Engine runs at constant speed. Generator sets are horribly inefficient at low power outputs. If they were very efficient at all times everywhere would generate their own electricity. Regeneration recovers potential and kinetic energy and stores it in the battery. Must be fiendishly complex, heavy and expensive. It is an attempt to cover all bases. Like all these things it is designed to get round US emission regulations. With all the usual hype about performance and economy which is proved to be a lie in practice. -- *Hard work pays off in the future.

You seem to be overlooking that it was Harold Wilson who took a successful truck and bus manufacturer and forced it into a shotgun marriage to the car industry that the unions had successfully bankrupted, then let the unions carry on as before ... You *really* should do some proper research. The idea that the unions alone were responsible for the demise of the UK car industry is so far from the truth as to be laughable. Stokes was a simple asset stripper, in essence. Not in the least bit interested in manufacturing. Unions are a very good idea in any well run industry.
