Trying to have the wheel serve more markets and also avoid start stop times at transfer stations.  Going zero miles per hour for short time kills average speed. The commuter rail system with concentrated ridership works, but most other rail posiblities beside freight, struggle to serve this giant county.  Travel between cities is rigid and often non existent here in the south.  It is this rigidness, that in some sense it the lure of train travel, but it is inconsistent with the demand responsive American expectation that air and interstate offer.  Why can't rail offer the same flexiblity in the market between long interstate travel and short air hops?

Intermodal128

The problem is that you cannot expect to build many successful rail trunk lines that serve markets build on the back of a web of highways. The highways caused development to be what it is. It shaped the development. The south grew up on highways for passenger travel over the past 50 years. Highway enable any OD pair to be valued more or less equally with any other so that high density lanes DON'T form naturally. Rail does exactly the opposite.

You won't be successful if you expect that a passenger rail can be built to serve the highway-caused market. It can find some niches here and there that will work, but real success won't come until rail starts to shape the development.

Folks here in the local advocacy group are starting to sweat bullets regarding the opposition that is forming against the ARRA-funded Madison-Milwaukee-Chicago train service.  Two candidates for Governor of Wisconsin are against it, the Mayor of Oconomowoc expressed opposition (but seems to be "backpedaling" for now), folks are out in force in Brookfield at Common Council meetings oppose it, and there is opposition forming in Dane County.

The advocacy community has been brainstorming about how to counter the "ignorance and misinformation" being spread about the train.  One of the problems of being part of the advocacy community is that one is so thoroughly indoctrinated in the inherent goodness of trains, through riding trains and being around like-interested people, that it comes as such a shock that there is so much, dare I say, hate, directed against trains out there in the wider community.

Trouble is, there is no ignorance or misinformation motivating the opposition.  Their "talking points" that spending 800 million dollars to facilitate, under optimistic projections, 300,000 yearly trips between Madison and Milwaukee is indeed, a rather inefficient use of the public dollar.  The Madison train only makes sense if you view it as a small, initial step towards Don's 50-year project to substitute trains for continued highway development.  Just about every highway "didn't make any sense" when it first went in either.

But just as those of us advocating trains can't see how anyone cannot see the inherent goodness of trains apart from being ignorant or misinformed, there are perhaps those in the anti-train camp who take a long-term view and don't want trains, especially if trains substitute for cars, that they like.  In other words, if the 800 million dollars is spent on behalf of a few malcontents who want their "choo-choo", what's a few million dollars in the grander scheme, but if the 800 million dollars is the "nose under the camel's tent" to end all future highway construction and put all effort into trains, well, we need to talk.

$800M is a pretty big investment to connect a city of about a 1/2 M to Chicago. Unless there exists significant pain in driving the to Chicago, I can see why many are coming out against. It may be that there will be significant pain in future years, but that is then and this is now. I think if lived in Madison and had to travel to Chicago, I'd drive down and take a Metra train in.

I wonder if the $800M wouldn't be better spent on Norfolk to Richmond - to connect the Tidewater area up to the NEC. New/improved NEC extensions have a good track record and the only fighting in VA now over this idea is whether it should go south side or peninsula! Both want it on THEIR side of the James River.

There is huge pain associated in driving from Norfolk to Washington DC right now. Both I-64 and I-95 are painful to drive.

Chicago has been a major pain as of late, and the Milwaukee-Chicago Hiawatha has seen a doubling of ridership over the last several years.  A lot of that is how they do things in Chicago and in Illinois -- every Tollroad along with the Dan Ryan Expressway went under construction all at once, tying the whole road system up in knots.  That situation is not going to last forever.

I don't see how Madison-Milwaukee is that big of a deal road traffic wise, and the opposition is making the new train out to be "800M for Madison-Milwaukee", and the advocacy community is going "no it isn't" and you get into this "yes it is, no it isn't" shouting match.

The argument in favor of Madison-Milwaukee is that it is part of a bigger picture, an incremental buildout of the Midwest Regional Rail Initiative, where continuing the line to St Paul is "Phase 2."  The other reason why Madison-Milwaukee got the ARRA award and, what was it, Austin-Dallas, or as you mention, Norfolk-Richmond didn't is that the people up here have been planning this thing for a long time waiting for money to come, and they fit the "shovel ready" critereon, although I don't see much shoveling going on right now as stuff takes forever to plan on account that everyone gets their 2-cents in these days.

It depends on whether you think that the 8 billion in ARRA money is a "downpayment on a network of high-speed rail" or if the 8 billion "is it, for now, and you had better do a good job and make a good impression on the public with it."

When you think of priorities and how we spend money on everything else besides trains, with a President who is the most favorably disposed to this kind of thing as anyone who has a chance of getting elected, trains get 1 cent on the dollar of the 800 billion ARRA stimulus, meaning trains are pretty far down on the list, even with people who would think kindly towards them.  Given the politics of it all, for better or for worse, I don't see another 800 billion stimulus coming anytime soon hence I think that 8 billion for trains is "pretty much it", which we have to make the most of.

Might be better if the $800M got you a not-quite-as-speedy Milw-Twin Cites instead of just a really fast right angle leg on two-sided trip to Chicago. Either that, or just upgrade Chic-Milw and extend out the other side to suburban P&R (tho' I guess it is the suburban stop that's catching a lot of the flak)

But, you are right. What ever the money gets spent on, it better not smell like a boondoggle 5 years out - or that will be the end of it for a long, long time.

I am sorry to hear about the struggle up there in the Chicago community over $800M and the competion with cars.  Land development related to transportation is something the "Public Funders" always have to contend with because the decision to create a project "targets" development and threrefore takes on Pork Belly overtones.   The success of the highway program was percisely because if free up market decisions regarding land development.  Its approach was considered realitively fair because it spread across many parts of the country as consistent format.  Rail related development is too specific and claims of favoritism spark uncompromising debate.  The only successful rail projects are those that improve existing markets not ones that create new markets.  The highway system freely promoted land development to anyone with a vehicle.

Your struggle is a no winner. (Perato Optimality, Econ 101)  It is very difficult to speculate with public funds unless there is a consensus future which the previous articles points out the absence.  But I will say that $800M over 300,000 riders is only $2667/ rider.  That seems to me as a returnable figure.

I wish we as a country get beyond these local battles and free up decisions for market forces to make.  The SFU (spilt flexliner unit) attempts to do this because it uses existing rail infrastructure while allowing more open access to the steel rails for entrepreneurs and innovated secondary economies to develop freely under free market capitalism. (If only Glenn Beck understood what he says)  No public decisions are made as to land development with the exception of where to allow entry-exist portals but that can be written into the regulations as an adminstrative code.  And these decisions would be fairly market oriented since the entry-exist portals are very inexpensive and require small acreage.

Our rail system can never be that of Europe or other old world countries because they do not have a highway system any thing close to that in the United States.  China could be an amazing partner in a new type of rail system.

The Split Flexliner is asking a railroad to do what is already being done by highway buses.  Also, the proposal as suggested by Intermodal 128 would require the legal issue of "open access" to be resolved.

Short comings of buses compared to rail are numerous.  Riding in buses is slow, uncomfortable, and bumpy.   Acceleration at stops and access downtown through lights and traffic terrible.  On the fly transfer between units impossible due to 3 dimensional travel where as rail offers one dimension and has direct line to downtowns on the smooth energy efficient steel rails capable of much greater speeds.

Legality to “open access,” what is all that about?

I think a nerve was hit concerning the notion of “open access.”   Who owns the rail corridors in Europe and other countries?  Do we maintain monopolies that prevent completion?  Where does rail ownership fit into today’s discussion on free markets and government regulation?

Rights of way in most of the rest of the world are generally government owned, a leftover from the period of nationalized railways (BR, SNCF, DB, RENFE, etc.).  Also, right of way ownership/upkeep and operation of trains is generally performed by separate entities.

Intermodal128

History: Rail right of way secured by private funding, built out in latter half of 19th Century.  US highways built with public money in 1920s and 30s (US highway network) and 50s-70s (Interstates)

Current Maintenance:  Railroad:  High tonnage routes and most secondary lines:  Generally excellent.  Highway: spotty.  Some in fine shape, some really ratty.

So basically railroads are monopolies.  They continue to operate using the same technology as from 1800s.  No competition and no reason to improve. 

Did the railroads purchase the land under the rails or did US Government help?  Is Amtrak a sign of public private cooperation?  Are there other examples of cooperation?

So, basically, railroads were monopolies 100 years ago.  They are most certainly NOT monopolies today.  The only technology that is the same from that era is that the rails are the same gauge.  

 

They compete fiercely for all types of traffic and are only successful in certain market niches where they have an advantage.  Performance, every way you'd like to measure it,  has greatly improved since deregulation.

 

Most railroad ROW was purchase with private money.  

 

Amtrak is not a public/private partnership.  It is a majority owned government corporation.  It has agreements with the freight railroads that allow operation of their trains on their tracks including performance incentives and penalties.

What deregulation occurred?

Yes they compete for traffic, but the true test of completion is entry in the market.  Monopolies imply barrier to entry.  My thoughts…… air and interstate compete within their niche, but railroads exercise monopolies in their niche.  The competition between niches is similar to US free market competing with China command economy.  We beat ourselves up, while China focuses.  Railroads focus on their individual line, while anyone can fly in a plane or drive in a truck or car and compete.

You should really read Mike Blaszak's article in September TRAINS to understand what was actually accomplished by the Staggers Act.  You also seem to assume that competition can only be within the same mode, which is not true.  Railroads compete with trucks for freight business and lost the competition with airlines for passengers.

Railroads compete tooth and nail for nearly all their traffic.   This is particularly true for intermodal.  If RRs were a natural monopoly, how did all that traffic they were handling in the 1930s - 1960s wind up on the highway?  How did (are) they getting some of it back?

I read up on the 1980 Staggers Act and conclude that it freed railroads to utilize their monopoly to operate at market rates and dump costly assets to achieve profits.  Regulation had certainly forced them into a hole and with rising completion from air and interstate something had to give before they went bankrupt.

Deregulation ultimate goal is to encourage innovation while preserving the public goal.  It is confused with monopoly power because monopolies can both be in pursuit of public interest or a detrimental to it.   While I as an entrepreneur can put a bus on the highway or a plane in an airport, I cannot put a train on the rails.  There is a market niche that I am prevented from entering and bringing competitive innovation, which is public bad.   The efficient nature of transporting freight is possibly a public good.  We should be able to have both these public goods: innovation (free market) and efficient transportation by freeing up the one dimensional steel rails.

Would your vision allow any rail operator to operate on Amtrak's Northeast corridor?  If I'm CSX and I want to run my intermodal train from Washington DC to North Jersey departing Washington DC at 6AM (so I can make my 10AM availability in North Jersey) that should be OK?  

 

What if that conflicts with the 6AM Amtrak Acela departure?  Who gets that slot?  High bidder? CSX would win.

 

What if more more operators show up with trains than the railroad can accomodate?  Who's the odd man out?  What do the "denied" trains do?

 

How and where are expansion projects done?  How do you fund them?  How do you know you picked the best ones?  The ROW owner wouldn't generally have his finger on the pulse of the operators' markets....

 

A railroad is considerably more complicated to operate than a highway or an airport....for a whole host of reasons, but most revolve around the nature of the fixed guideway.  

 

You want to stop innovation on the RR right in its tracks?  Open access is the best way to do it!

I was first terrified over addressing the first sets of questions about capacity and bidding for space.  The last two statements allow for the further reaching solution concerning SFU discussed in earlier post. 

I present this…….instead of thinking about rail travel as incremental trains bidding for space on tracks and stations, try to imagine continuous flow of  SF units that merge and exit the rails without stopping.  While Amtrak and the Acela fade into depreciation the space between trains, the excess capacity, can be utilized as SF units enter and exit the rails without needing to stop or interfere with existing rolling stock.

The fixed rail is the key to regulating capacity as units merge because it is one dimensional allowing computer programs and GPS can regulate the flow.  The ultimate problem, once safety is engineered, would be possibility of having bumper to bumper jams.  But would that be actually a sign of success and a good problem to finally have?

Here is "A" vision--something nobody else seems to notice.  The route of Amtrak's most successful train is not included in any high-speed rail plans.  Trains ran a map of "By Train to Florida, January 1953," (December, 2009) and there were about thirty trains a day crossing the border.  Now we have three--none from the west or midwest.

I see a route that is neglected because the airlines want all the business.[View:http://cs.trains.com/trccs/themes/trc/utility/:550:0][View:http://cs.trains.com/trccs/themes/trc/utility/:550:0]

You want to stop innovation on the RR right in its tracks?  Open access is the best way to do it!

 

I think we have already hit the limits of "Open Access" with the recent regional 110 MPH train corridors deal.  Trains Magazine is reporting that some railroads are getting cold feet about accepting the government money to upgrade their own lines.

It seems that the gummint wants hard performance guarantees for on-time passenger trains from the host railroads, and I can see why, given the by-gosh-and-by-golly on-time performance of much of the Amtrak network and the recent dustup about poor on-time performance of the upgraded Illinois trains.

The railroads are turning around and saying, "There is a lot of capacity on our network now, but what happens when the economy picks up and traffic levels are back up to normal."

It has long been an article of faith and of conviction in the advocacy movement regarding "must" and "shall" with the host railroads giving absolute priority to passenger trains.  I know of more than one person who regards the government funding of track improvements as the camel's nose under the tent to enforce "must" and "shall" -- the advocacy people regard this not as a bug but as a feature, and the railroad companies are catching wise to it being the other way around from their vantage point.

You know, Don, you once promised to explain this "slot" concept of track utilization to us and how it affects Amtrak on-time performance and the capacity of a line to accomodate high-priority traffic such as more passenger trains.  I know you are busy and have a day job and everything, but if more of us understood this "slot" thing, there would be a better appreciation in the advocacy community of what can and cannot be done with some of these passenger train proposals.

W.r.t. fixed guideways, what I meant was switches are expensive.  A truck can pull of to the side of the road anywhere.  An airplane can taxi anywhere off the runway.  A truck going 65 doesn't have to think very much about how and where to get around one going 55.  That's a huge deal for a RR.  Providing switches and tracks so a train has "alternatives" =  mucho dinero!

Passenger markets are trip time driven.  Coal shipments are fuel cost driven.  So, the sweet spot for passenger travel may be 110 mph and for coal, 40 mph on the same lane.  Making both go 70 mph could mean you miss both markets and wind up with nothing.  

 

That makes planning and regulating the flow of trains much more difficult than for highway and air.  

I think the kind of system you are talking about is best adapted to highways.  The only difference between a highway and railroad is the fixed guideway, so the only piece that needs automating is the steering.  Not insurmountable - that's been around in analog form since the 1960s.  .The only hard science difference is rolling resistance - some targeted R&D could close that gap a bit.

 OK.  Sort of.  But, NY-DC-Richmond-Raleigh-Charlotte-Macon-Jacksonville is on the high speed map.  That suggests to me that the shorter, intermediate markets are what would make HSR go in the east.

Yes.  The issue of open access and capacity and the difference between rail, highway and air is steering ie switching.  The devil is in the details.   How does the light high speed SFU pass the 40 mph coal train? 

First perhaps incorrect assumption is the coal train a fading relic in congested corridors and lesser freight trains are capable of increased speed?   Not that this eliminates the problem in any way, but it is part of a national energy policy reflecting the market and comprehensive approach, and general track infrastructure improvement.

Second assumption is that increasing coal speed from 40 to 70 is minimal fuel increase solved by tech advances holding safety constant in the long run.  So how does a high speed SFU pass a 70mph freight train?

Answers…..

First; is the same 150 year industry standard of siding approaching 3 to 4 parallel tracks, but expensive in the congested corridors with limited space.

Second; the SFU simply stays ahead of the coal train and stays the hell out of the way.  Because the SFU does not stop at stations, Units exiting and entering the tracks easily, the coal train never catches up. 

Since a freight “train” is moving at a constant speed the time caught behind it can be calculated and decision to exit tracks in favor of highway or to move up start time by SF Units can be adjusted to get out in front.  On a 30 mile stretch between sidings, behind a train doing 60mph instead of 120mph, the time cost is 15 minutes.   The Units, easily able to enter and exit the rails, are free handle this as they see fit.  It becomes a mathematical calculation because tracks are one dimensional, with losers being responsible for their own delay.

This will lead to SF Units competing for space in front of the train, which becomes a per density and rationing calculation based on a mathematical program that the airline industry uses.

Get real!!  The passenger train may be ahead of the coal train but it has to be behind something else.  Coupling at speed is an accident waiting to happen (and probably will) since it has to assume that the lead train will not have to stop for anything.  Your operating concept is based on a perfect world in which everything works exactly as intended.

If SFU is caught behind something else, a slow freight train, that would indicate congestion of frieght trains that are so close together it demostrate a total lack of capacity.  If it is behind another SFU then passengers move between coupled cars and the exiting units drop off at the station while SFU train continues.  I would imagine that siding are availible at some point to pass the slow freight.

These SF Units are designed to couple.  We can do it in outerspace, we can do it on solid one dimensional steel rails.

Perfect world...once the Units enter the track system, they become mathmatically perfect because there would be codes  required to enter the track system governing the position and height of coupling.  It is absolutly consistent because the steel rails create a point of coupling that is always in the same place vertically and hortizontally.  Speed ie time is the only variable.

That's the expensive part...

If we can do it in space, we can do it on a road. One less degree of freedom.

Yes government involvement in highway does provide more freedom to pursue docking, but too many varibles and cars get in the way.  The tracks are there and one dimensional where cars are 3 dimensional. 

The SF Unit's ability to easily enter and exit tracks lessens need for siding.

Last night watched a CSX coal train lumber back from Norfolk empty heading to western mines.  Only train that passed during 1.5 hours while I was there.  How often do these things travel in the North East coridor?  I imagine coal train fequency is a clear function of power plants operating near their electric market.  National energy policy to transport electricity by transmission line instead of in coal cars plays into things.

This Split Flxible Unit concept has a couple other flaws: will there be another unit to couple to; and wouldn't closely following units be subject to slowing to create the necessary gap for the entering or leaving vehicle?

Aside from the risk factor involved if the lead train has to go into emergency braking, the mechanical factors of coupling on the fly have not really been addressed.  If the equipment has conventional air brakes, how do you connect the air line?  Also, connecting the m.u. lines has to be considered although a system similar to some rapid transit equipment might work.  I also don't think that intermodal128 has any idea of the time involved for even a power switch to be aligned from one route to the other, plus clearing the signals.

The daily commute is part of everyday life but I get two rides a day out of it. Paul
