If a freight path is not used for a certain period then there are mechanisms within track access contracts to remove them.

So they will run a light locomotive or a very short train of empty wagons in each freight path every few weeks/months to ensure that they keep them.
--- old post above --- --- new post below ---
Surely there are more than 50 lorry loads on a 775m container train?? On many routes though, there's space for both the passenger train and the 775m freight train (and part of the solution has to be to find ways of pushing freight away from busy passenger corridors and onto these quieter lines?).

50 40ft containers comes to 606m, then you add in some slack length for the couplings and that comes to ~650m, then 20m for the locomotive.
Then you have to account for the fact that there will be empty slots on almost all runs.

And then you find out you have little change from 775m.

Frankly the trains need to be far longer than that to really work economically without huge subsidies.

http://www.lloydslist.com/ll/sector/containers/article426672.ece?

this is a 3rd running line to be constructed along the freight only Betuwe route so obviously there are a lot of containers unloaded in Rotterdam and the train clearly has much demand vis a vis inshore shipping although i have no idea what size of ships can use the various inland european waterways.

That is not the Dutch Betuwe route, this is the German line that connects to it. The actual route is nowhere near its maximum capacity, and will not be for years as its hard infrastructure has been sized for double stack container transports.
In fact in the Netherlands the entire project is widely considered to be an enormous white elephant.

And the fact that it is a freight only line is a major point.
Mixing freight and passenger operations is a bad idea economically.

The idea that some of you are suggesting that we shouldn't even care about railfreight is bizarre. Even diesel hauled freight is less damaging to the environment then is road freight and that is without considering accidents, congestion and the affects of 40 tonne HGVs. Rail's great advantage be it freight or commuter lines or HS2 is that it is the least damaging way of transporting people or goods and far safer then road transport. Remember 1.2 MILLION people die on roads worldwide. This is a shocking state of affairs which shows how addicted we are to road travel

You want to reduce road deaths by reducing the number of lorries, I want to reduce the number of deaths by using rail capacity to take people out of the firing line by using all available resources to improve passenger services.
Improving travel times by raising maximum speeds reduces overall capacity but will significantly increase passenger patronage.

yes I know that the Betuweroute is in the Netherlands but the line in question connects with it and will increase the number of trains using it. There is still a huge amount of Hgv traffic on the european roads.

Hs2 will provide a massive capacity uplift for carrying passengers and will release capacity for more freight on existing lines. This will allow the railway to take more cars and hgv's off the road which is what we all want. Regardless of the limitations of 775 metres, one such train still potentially removes 40 containers from the road for at least part of its journey.

But the path that is used by the freight train could potentially take hundreds of cars off the road for at least part of their journey.

It is not a question that it would be nice to have more rail freight, just that railfreight is not the best way to reduce environmental damage in a socially responsible manner.

If we could have a double stack-enabled (and thus TOFC capable) network of freight only lines then that would be amazing, but at the moment we are running very light very power-heavy trains on a passenger orientated network.

Surely the radical , rational and logical answer is to actually provide enough rail capacity for both freight and passengers

HS2 would not come close to doing that.
Even with the drastic service realignments I have proposed for the post HS2 WCML it is unlikely that there would be large amounts of additional freight capacity available.

Passenger services always bring in superior press.

The only way to get enough freight capacity would be to cobble together dedicated freight routes, but that is never going to happen.

.
We don't run light engines or short trains of wagons just to hold onto our paths, what utter cr*p! Light engine moves happen for a reason, the nature of the job means there are sometimes unbalanced workings where a loco is required elsewhere which cannot be attached to the front of another train, or a set of empty wagons is required by the customer at short notice. Some paths are used by other ad hoc workings to balance jobs out. There are probably just as many empty stock moves as there are empty freight / light engine moves, yet nobody ever mentions this. We move our locos and wagons around to suit our customer's requirements, it's as simple as that.

As for running longer trains (and I can't believe I'm having to explain this to you), in an ideal world it would be just the job, but surely someone as intelligent as you realises that the longer and heavier our trains become, the longer they take to stop.... which would affect capacity in a very big way since the signal spacing governs all of this...?

HST'ed whilst most of your views I agree with your thoughts on rail freight baffle me. As was mentioned before port Salford is going to see a huge increase in intermodal freight as its definitely going to be rail linked (infact it's the main reason why the freight terminal at partington on the old shell site was never built).

You talk about indirect subsidiary to rail freight, however road tax for your average lorry is pretty low compared to your average car when you consider the damage a lorry does. Look at the fact that roads don't have to pay their way and you can see that it's hardly a level playing field.

Any way this seems to be getting a bit off topic.

But you could still run a classic compatible TGV into Nottingham without any problems. Along with a service into Derby and a service running from Sheffield calling at Chesterfield before linking up with HS2 at Toton.

Apparently the benefits to Chesterfield and very minor benefits to Sheffield are worth a half-path? (Once you account for the drastically increased travel time to Sheffield I doubt you will be up at all frankly).

"If" there was ever to be a HS2 classic compatible train serving Chesterfield if would need to be direct via the Erewash Valley Line from Toton of offer any benefits in comparison to what the journey time would be via the MML (remembering that by that point in time the MML with have areas of 125 mph running, as well as other line speed improvements, and the benefits of electric rolling stock), as going via Derby would take reasonably longer, due to having to reverse at Toton for Derby (unless you are proposing a direct HS2 link south of Toton for a Likely single train an hour) plus the additional time of a journey via Derby from Toton vs via the Erewash.

I'm afraid with that kind of attitude Toton will become a White Elephant.

As I have stated before, in my opinion the services that serve the Toton station would be in addition to those running on the MML. So ie 4-5 tph to and from London from and to Derby and Nottingham each in effect (2 via the MML and 2-3 via HS2). Also the Toton station will not just be serving Derby and Nottingham, but the whole surrounding area of those two cities, practically those close to the Toton station. Long Eaton and Beeston for example would be very conveniently located for the Toton station, of which both already see direct hourly services to London.

I don't care about freight.
I wouldn't shed a tear if intermodal freight operations vanished in a puff of smoke, they guzzle paths like no tomorrow and burn vast amounts of diesel on electrified routes.

No they don't, a Class 4 freight on the southern part of the WCML eats up less than a stopping service. If a Class 4 is put in front, it gets away from the one behind it.

It is a fact that rail freight is growing massively, and HS2 by freeing up capacity of the WCML fast lines will allow semi fast services to move from running on the slow line to the fasts, and as such then freeing up capacity on the slow lines for more slower passenger services and freight. As has been stated stopping services can live very happily along with freight. Capacity issues only occurs with freight when they have to run in between much faster running services. As such I can not see what your issue is with freight running on the WCML slow lines, unless you want a tube style frequency of services stopping all stations between Milton Keynes/Tring and London, which is surely overkill even given the current passenger capacity issues?

As for premium pricing, the way I view it in the case of HS1, is that the only reason for it is because the subsidy that Southeastern currently revives is only for its classic network services and not those which run on HS1. As such it means that Southeastern has to charge a premium for tickets valid of travel on their HS1 services to make up for the lack of a subsidy for running those services. The situation with HS2 however will be completely different in that the TOC running the HS2 services would be a premium paying one, just like Virgin on the WCML and East Coast on the ECML, which would mean its costs would be covered by the revenue it makes. Also Southeastern does not sell advance tickets. So is unable to use advance ticket as a method of yield management, ie pricing advances at a price relative to how much demand is expected on each service.

Was the explaination not already given: stupidly high walk up fares? From the TOC's point of view, it matters not that the trains are full, only that they are making money.

I suspect that the business case is always going to be a subject of debate because of the nature of the project. If we ran our railways purely on their financial cases, we'd close almost all of them and tarmac them over.

I personally am convinced about the need for HS2 from a long-term operational perspective. I'm more sceptical about the "lowering the north-south divide" aspect, as to me it sounds like political mumbo jumbo.

Yes, the walk-up fares is the best explanation given for the ghost trains, but Virgin do not operate any of their airlines on that principle. I know they usually operate against other competitors, and I know Virgin is just the brand, but the principles of yield management are the same.

In fact, Virgin Trains are worse than this - they have TWO opportunities to offer better fares, firstly through the open tickets (not likely, but first offered a 15% reduction) and secondly through the advance tickets.

I totally agree with your point about the externalities, but these can be factored in to a BCR equation, and there is already some allowance for these, as rail tickets are not subject to VAT, and the power is not subject to fuel duty at the same rate as auto diesel.

In the meantime, the environmental argument goes out of the window when you are moving so much air around at a time when you should be full.

This is the problem I have with people who say that they are against HS2 which we know you are because of your highly original username. In a sense there is almost no point in conversing with you.

The username should speak for itself. I am critical of HS2. I think the scheme is deeply flawed. I have argued for high speed rail before. This is a very poor version of what I had hoped for, and frankly, in its current form, I will not lament if it fails.

As for the conversation, when was the last time you heard a film critic walk out the cinema going "god that film was rubbish, I hate film, I wish film had never been invented?"

The purpose of any critique for an infrastructure proposal is to look at ways it can be improved. So the Whitacre proposal would make a big difference to Coventry. Renaming it Coventry West Ryanair Parkway would not, as Birmingham Airport + NEC would veto that.

I have already asked for, and been given, reassurances that the section of greenway around Burton Green will be rehoused.

I have asked, and will continue to ask, Centro to keep a focus on local details as they rev up their support for HS2.

If you don't like what I say, that's your perogative, but please don't pretend I shouldn't come here and say it.


I understand that you dont want HS2 built near you and have genuine concerns re the post HS2 service that Coventry will be offered. I therefore find it incredible that you not only profess to love high speed trains but ADMIT that you have used EUROPEAN high speed services apparently on numerous occasions !

You are falling into the trap of calling someone a nimby, but trying to skirt round the edges of saying it.

If I was against this for nimby reasons, what would be the point in debating it in a rail forum? On the latter point, yes you are indeed correct, I do have concerns about post-HS2 Coventry.

However, that is only one of my concerns. My starting point if we wind back to 2003 when we were talking about new airports was that we should promote rail over domestic air. The sad reality is that HS2 can't and won't do that, because rail has already won the battle around the Manchester axis, but HS2 alone does not offer enough savings (-C/c deficits) to make a huge difference on Scotland's Central belt.

One wonders if you had any thoughts at all about those displaced or affected by those high speed lines you have used, or that these lines were white elephants or that their various business cases did not add up !

Not my problem. Go back through my posts. Have I EVER said on this thread "we must save our countryside" - other than in the context of recreational routes that are already there?

Equally not my business looking at the business case for a project in another country.

The cynic in me has the sneaking suspicion that the main reason you are opposed to HS2 is because it will (a) run near you and (b) not offer Coventry a station other then at NEC / International / Interchange !

I think I've already made it perfectly clear that (a) is not so and (b) is very true. Coventry is just getting going as a cycling city, and has already made a lot of improvements to become more walkable in the city centre, not to mention the massive Friargate proposal. It isn't just about the potential need for changes to get to/from London, but also the fact that relying on a parkway station creates more of the very car dependence advocates of HS2 are claiming it will mitigate. If that is so, we need to be building genuinely integrated transport, and not parkway interchanges dressed up as such.

If the business case dint make sense the why would Germany, France, Japan, Taiwan.... All have high speed rail. Don't think they would have built them if it wasnt a boost to their economy.

The last time I saw HS2 being discussed on BBC Parliament, it seemed that capacity was being 'sold' as the big benefit, not speed.

Of course, you'd hardly build a new line that didn't allow trains to go faster than they do today - but perhaps it should have been named differently, pushing the capacity enhancements rather than faster journey times.

To be fair it does what it's says on the tin, second uk high speed line! Also "railway to fix the impending west coast mainline capacity crisis" is quite a mouthful!

:roll:
That should only be the case if the additional wagons were unbraked. I think it's safe to assume that continuous braking systems of one form or another would continue to be in used in such a scenario, and hence that the braking force would scale linearly with the number of axles (ie. with train length). As such stopping distances would be unchanged.
I would have thought that the availability of loops/sidings/etc. long enough to hold them would be the bigger constraint.

This is only true when you are living in the Victorian railway and still using traditional air brakes.
Look up Electronically controlled pneumatic braking - acronym is ECP.
A 12000ft train stops in almost the same distance as a light locomotive since all brakes come on at the required brake force instantaneously, and you don't have to wait for the train line to re-pressurise to enable you to move off.

That is the future of freight train operations.

The WCML needs reduced traffic over it so we can have improved regional services and so we can stop pushing ageing infrastructure to the very limits of its capability.

Lashing out like a cornered toddler will only serve to make your arguments less credible which is a pity as you clearly have something to bring to the table. With your attitude to intermodal traffic on NR I can only assume that you are not a regular user of our motorway network? In terms of road users the best thing we can do is to try and take more freight off the motorways.

Whilst I'm in agreement with you regarding the rate of rail freight expansion, it’s absolutely ridiculous to suggest that the WCML should not be used to carry intermodal freight.

That's a fair point but how would you rate the business case for the Carnforth - Settle Junction route? And yet of course no one wishes to close it! There will always be a time and place for motorways but I wish we could do more to take freight off the motorway.

Twelve thousand feet...? I think you've made a typo there HSTEd! I can assure you from doing the job myself that a light engine stops in a lot shorter distance than the two to three thousand ton freight trains I drive day in, day out. (Most of our current stone trains are just over a thousand feet in length by the way).

I'm not doubting that a long and heavy freight train takes some stopping - but surely a longer train means that more brake force is available? Isn't one of the significant factors therefore the length of time taken to apply (and release) the brakes through the whole train, obviously with due regard for the forces transmitted through the train in the process? This ECP business might have some mileage then, if it actually exists and is a realistic option (no guarantees, of course, given some of the nonsense that's spouted around here from time to time).

BTW, don't believe all that Peel Ports tells you in their glossy brochures. They have a vision of creating an ants' nest of container traffic in the north-west.
Peel acquired the MSC (MD&HB & (Barton aerodrome)) many years ago and freed up under-utilised dockside assets (AKA asset-stripping) but there has been no quantum leap in ship traffic and that's what all the hype is supposed to remedy.
I don't forsee any significant re-orientation of freight distribution on this account.

Yes, sufficient brake force is available but the sheer momentum of a loaded freight train is much, much higher than that of a light engine. Putting the brake into 'initial', you'll still travel a few hundred yards with a loaded train before the brakes begin to bite. Trust me, I do this for a living...! A longer train means more weight and more momentum.... you can't argue with physics ;)

I dearly wish I was able to give you a cab ride to prove my point, but alas it's out of the question these days ;)

Ah, the same Peel who promised South Yorkshire a thriving Airport that would be the only UK-one outside London to be able to handle the biggest planes?

Apart from a handful of cheap flights to the Med and a couple of flights for Poles working in the UK, if the wordy Robin Hood Doncaster Sheffield Airport is anything to go by then I really don't trust the "glossy brochures" that Peel provide!

I'm not doubting you, honestly! I'm referring to HSTEd's mystical ECP system that promises to instantaneously apply the brakes throughout the train, whilst doubting that it's a realistic possibility ;) .

My employer keeps threatening to release me for a cab ride through our patch one day (which we're supposed to have before passing out for a location!), but no doubt the fact that us mere signalmen aren't considered worthy of PTS would mean that we'd be limited to a passenger train formed of a DMU anyway, such is the way of the modern railway.
