I accept that Crossrail overan, badly, but how much scope was removed, i.e. start scope v delivered scope. To me its this that lets HS2 down badly. The curtailment to a London Birmingham route with little propect of the original Manchester and Leeds final desinations being reached in any...

Putting aside all the arguments about what should or could have been built, I see the biggest problem as being the impact on any future rail infrastructure priojects. The huge overspend, scope reduction and delays are an ongoing PR disaster. This means that it is very unlikely that future...

But you dont get full speed over the whole section anyway, the last 10 miles ish into London is 250km/h/155mph anyway, and then by the time you accelerate and brake how many miles of higher than 186mph 300km/m running do you actually get between London and Birmingham? As for the original...

I think the real problem area could be early analogue stuff, digital is easier to re-engineer. As an example from a few years back I replaced 6 very early digital Telmecanique PLCs dating from around 1980 (Programmable Logic Controllers). We had the original ladder diagram printout, on on very...

Exactly, even if HS2 reached its original destinations the distances are around 200mile/320km. In France Paris Marseille is around 470 miles (770km) and there are quite a few trains from Paris which are first stop Avignon which is well over 400 miles. In China the longest possible HSR journey on...

My concern would be early integrated circuits, there is a lot of stuff which is just not available today, either through mainstream suppliers or the secondhand market. Passive components are not a problem, I can still buy a 100ohm 1/2 watt resistor or 100uF 16v electrolytic capacitor, it may...

As a regular traveller thanks to those up thread who explained the difference between RTT and App based running info. I use both, as I had realised that 'Apps' often dont give platform numbers, but App based results can be more accurate in some conditions Where there is queueing and the...

I think part of the answer lays with the way London developed during the Victorian period, by 1900 development had spread south out to Clapham (Hence the C&SLR tube in 1890) where as to the North development pretty much stopped at Hampstead. I grew up in the area around Clapham South tube...

Hydrogen Flouride is a serious hazard, it forms a corrosive solution with water, if it gets on the skin it can cause serious injury and is absorbed leading to serious and difficult to treat injuries. Certainly not something to be treated lightly.

If you opt for the cheapest fare then its pretty simple, but if you want to see the options then there are loads of options, I will often check the price differential between some sort of open ticket (typical off peak day return) v Advances, and if the difference is minimal I buy an open ticket...

When I say milage based I dont mean the same pence per mile rate over the whole of the UK, My thinking is to do it on a per route basis. Again back to the example of our local route pence per mile rates vary from from 19.8p (Scarborough - Hull off peak day return, cheaper deals can be had for...

I agree with @ChilliSauce that the current system is broken. My own view is that for starters all tickets should be issued by 'GBR' with no reference to a train operator. If you want to encourage the use of certain routes or services use the advance fare differential. As I stated in another...

I live in a vllage which has an hourly service to Doncaster and Sheffield, which give good connections for a lot of onward journeys, so train is potentially an option from a time/convenience point of view. Certainly talking to potential users locally ticket and fares complexity does put people...

Simplify ticketing, you only really need Anytime, Off Peak and Advance. Integrate bus services with rail, particularly in less populated areas, with through ticketing. Ensure that there is sufficent rolling stock to meet normal (i.e. apart from special events) demand, and even if it is old...

To me the ability to run longer trains is key to getting the most out of a route like TPE North. It should be a simple way of increasing capacity. 3 and 5 car units are using up capacity. This is the drawback of the units purchased, buying additional carriages and strengthening existing units...

I am going to nominate Bridlington Location is OK, in the town centre, and not far from the sea front. BUT Its open with insufficent dry waiting areas in the winter, just open shelters at each stop. No overall information boards telling you which stop buses go from, its fine if you know but...

To be fair I wasn't suggesting through services to France and beyond. The border control issues are insurmountable Which I think might be a good thing in the longer term, I am not sure that two high speed stations that close together is a good idea.

Going to add my thoughts: Not making a connection to HS1 has to be a huge mistake. An underground 4 platform Euston/Kings Cross/St Pancras station, with trains terminating out at Ebbsfleet where there is a lot more room, land costs are lower and disruption would be less, calling at Stratford...

I think another factor would be what they contained, spent fuel would I think be more of a concern than fresh fuel. Having seen the flasks I think the 800C for 30 minutes would be very conservative unless there are other aggravating factors, e.g. coupled with mechanical damage. Fires involving...

I actually suspect that nuclear flasks are less of a problem than some other materials that are transported by rail. The 1984 flask test proved that whilst the contents are dangerous the flask is going to pretty much stand up to any foreseeable accident. Over the years the dangerous cargo rail...
