WHY?

Are you made out of endless financial resources? (Catenary ain't cheap bubba)

All you are doing is moving the emissions point source using electric over diesel?

How long till you get your investment back?

You think the same amount of current made at the plant gets to your catenary out in the boondocks?Laugh [(-D]Laugh [(-D]Laugh [(-D] 

 

Reality check!

     Seems to me, that railroads switched from electri to diesel-electric for a reason.  Diesel-electric was more cost effective.  It still is, or the railroads would be stringing up catenary wire.

Electricity isn't free.  It has to be made by turning a generator or alternator.  To turn that you need hydropower in a turbine or steam.  Steam is made by burning a fossil fuel ( coal, oil gas, etc.).  When you use the fossil fuel you do not get 100% conversion  to energy dues to friction and process losses.  If you took  the fuel and used it directly to move something the efficiency is much higher than converting the heat generated to steam and then to electricity.  electricity is the highest cost power there is. Now add the cost of catenary,  reapir costs when you have an accident or storm damage and it it doesn;t take long to see why CR got out of the electric engine business.  In addition you need high usage (corridor).  As a PRR efficianado I can tell you you can;t justify it today unless you are Amtrak and you got it handed to you by the feds for about 2 cents on the dollar when PC collapsed.  I susect if the PRR was around today its electric operations would be cut back to the tunnels in New York like it was originally.

During the 1970's energy crisis, UP thoughly evaluated the electrification of the Ogden - Green River line.  As far as candidates for electrifiction, this one has most all the pluses, high traffic density, approximately balanced uphill/downhill traffic (dynamic braking on the downhill helps power the uphill), access to the electrical grid, and management support.  UP even owned the coal that would fire the added generating capacity.  They went so far as to install a couple of test sections of catenary to evaluate weather and radio communications impacts.  GE was even pushing a great new electric locomotive for UP to buy.

In the end, even with all the plus factors, UP said "No!" and maybe even "Not ever" if you believe some of the rumors.  Electrification simply cost too much.  Still does.

Electrification: Great for high-traffic lines, but it becomes highly uneconomical when the business dries up.  See for example the many former Pennsy lines here in PA that still have the catenary support posts next to the tracks, but no wires over them any longer.

It depends on what you have to pay for oil as well as your traffic density.  For example in Europe Electrification rules with the exeption of the UK  because it is cheaper than using oil.  Think in that context oil has to be imported and is taxed to the hilt.  It skews the economics.   Obviously UP in the 70's was concerned about the future price of oil that they strung up a bit of 25kv 60hz to test for things like signalling interfence.

I like belching diesel locomotives.  And, right now, I could use a little global warming.

Seriously, it's too much of a risk.  Electrification has been studied.  I'ts a "bet the company" propositiion.  If things don't work out the right way 10 years down the road, the company will be taken under financially.  Not a good bet.

In Europe, the trains may be electrically powered, but that freight is going down the highway behind a diesel tractor.

I'm just your average, everyday, uncivilized howling "anti-government" critic of mass government expenditures for "High Speed Rail" in the US. And I'm gosh darn proud of that.

A belching diesel is an inefficent diesel.  The best thing the rail idustry to do to reduce it's CO2 emmissions and reduce its fuel bills is to keep a up to date and well maintained fleet.  Compare fuel consumption/emmissions between an SD40-2 and a SD70e or a U30c to a EVO series engine and you get the picture.

1.   Remember that the New Haven reelectified while in bankrupcy to SAVE MONEY!   Admittadly, most of the electrification was subsidized by the Connecticut and New York subisidization of commuter service, but they did have to put back the wire between the New Haven RR. Station and Ceder Hill Yard, also at the Oak Point Yard in the Bronx, and along the Long Island railroad's Bay Ridge branch to the car floats at Bat Ridge, owned by the LIRR but operate and maintained by the NH.   And they bought the ex-Virginian-N&W electrics.

2.  The problem with the PRR electrification is that traffic patterns shifted.   The main line was the corridor, and once Conrail was running the operation, the freight was shifted off the corridor onto the CNJ-Reading-B&O line.  So what remained were really branches.   Sure, the Harrisburgh electrification was main line, but the freights ran through to Pittsburgh, bypassing the Enola change point.   And all New England freigth was relocated via Selkirk and the Boston and Albany, with neither the West Shore River Line nor the B&A electrified.

3.  Some day the UP main line will be electrified.  When technology advances to the point where a combination straight-electric-diesel-electric costs perhaps only 20% more that a pure diesel.   Then it will make sense.   What I mean by straight electric in this sense is one capable of picking up power from 25,000Volts 60Hz (cylces-per-second) AC.   The current dual-power electrics used by LIRR, Metro North and Amtrak are all third rail dc electrics, and that is relatively easy.   What are needed are more efficient and more compact transformers, and the limitation on compactness is heat build-up.   I am sure GE is working on it.

4.   And the two most heavily traveled British long-distance main lines (if anything in the UK can be called long-distance) ARE electrified.   And rail freight is making a comeback in Europe and some is electric and the coal stuff that always remained rail is mostly electric.   In fact, the first commercial power (in Europe 50Hz, not 60Hz) electrification was in France specifically for hauling coal!

The return on investment to electrify major rail routes is not measured in idealism, efficency or effectiveness, it's carefully measured in that man made "other" resource-money, utimately perhaps, depending on which side of enviromentalism you prefer, is scarcer these days than the dependability of the natural ones. As the thread on the DM&E aptly demonstrates, as a community and a nation, we have no common vision of the greater public good. As a more practical matter, we simply could not afford to underwrite the project even if it were imperitive that we should. Our European brethren have lines that are largely electrified, and are running trains that make the NEC look like a 19th century Lionel on a tight radius circle of track. Electrification will never occur here....we are smarter than that.... 

Perhaps technology outpaces our opinions and this situation could change...see link below:

it would be a lot cheeper and effecient if they went to 400hz instead of 60 hz. All the controls would be smaller and more effecient.

Once they standarized 400 hz the cost would drop considerably.

Turbines in stationary power plants run at constant rpms so they are far more efficient at generating electricity then the variable deisel engines in locomotives.

 

If our freight railroads would run shorter more frequent trains, service would improve for shippers by offering more frequent or more direct services. Shorter faster more frequent trains would allow electrification to be far more advatagous and beat the deisel in efficientcy. Right now the railroads run on desperation, desperate to improve bottum line with run down, dirty deisels with over length and over weight trains with poor service to save on cost. This makes electric trains look bad, but if the railroad was truely running efficiently you'd probably see money for main lines with catenary.

The PRR had big plans for electrification....in the days of steam.  The plan was to electrify all the way west to Pittsburgh.  They got only as far as Harrisburg before events overtook their plans.   The final blow was the advent of diesels.  It turns out it's cheaper to maintain a couple thousand small diesel power plants than pay for lots of wire and transmission losses.

After the energy crisis of 1973/74, and then in 1980, the RRs took another look.  The most ambitious study was one the DOT took as part of the creation of Conrail.  Even at the height of diesel fuel cost, the height of nuclear power and with the cheapest possible construction - wood poles for catenary supports - it didn't have a positive ROI.

Since diesel is currently cheaper than it was in the mid 1970s and early 80s and those locomotive mounted power plants are even more efficient than they were back then, there is absolutely no reason to electrify.

Two other trends will continue to postpone major electrification in the US.  (1) Diesels are getting cleaner so the smoke issues have been diffused, and (2) the price of copper and aluminum for transmission lines has skyrocketed.

Best long-term bet (50 years) for replacing diesel from my studies will be hydrogen powered engines (either fuel cell or conventional) with nuclear reactor based hydrogen generation.

Well, electricity is relatively cheaper to diesel fuel than it was 30 years ago, too.

And production efficiency of a modern coal fired plant is greater than it was 30 years ago.

And pollution control equipment for modern coal fired plants is much more advanced than anything that has happened with the basic diesel engine over the past thirty years.

What has changed from 30 years ago is utilization of track capacity, and electrification offers a 15-20% increase in track capacity.

A proper analysis of electrification today, in fact, includes cost advantages in capacity returns and avoided construction costs that were not present thirty years ago.

A proper analysis would include:

1. Cost of fuel.

2. Equivalent cost of electric power. Currently, the cost of equivalent electric power is about 54% of the cost of diesel at $2.20 per gallon. For the DC systems I am familiar with, about 72% of the substation metered power gets to the rail. This results in an equivalent electric power cost at the rail of about 76% of the cost of diesel fuel.

3. Cost differential due to regeneration. For a typical Western railroad profile, 15% of cost at the substation meter can be recovered by regeneration, offering a final equivalent electric power cost at the rail in favor of electrification of just about 65%.

4.  Cost of financing. Currently, these outweight the fuel savings on a 15 year basis. At 9% financing cost, diesel fuel would have to reach approximately $3.01 per gallon before the savings in diesel fuel costs justified the direct costs of electrification.

5.  Cost of financing -- service life. The cost of financing the diesel-electric fleet over a 30 year period substantially exceeds the cost of financing of an electrification system because of the economic service life of the diesel electric being currently between one-fourth and one-half of the economic service life of an electric.

5.  Salvage value. The cost per rail hp of diesel vs electric is about the same. The cost of the diesels "displaced" by an electrification would be a credit to the cost of electrification.

6.  Depreciation. The depreciation costs of the diesel-electric fleet on an 8 year depreciation cycle substantially exceeds the depreciation cost of motive power and overhead on the accepted depreciation cycle for electrical equipment of 30 years.

7. Avoided cost of capacity construction. At a 15-20% increase in track capacity, the avoided cost of new track -- particularly flat vs. rolling vs. mountain construction where new capacity costs are almost directly proportional to operating savings from electrification due to regeneration.

8.  Higher revenue from expanded capacity on existing track vs the friction costs of greater capacity on existing track.

9.  The cultural and corporate resistance of professionals who don't know anything about electrification and who would be ceding jurisdiction of important components of their areas of expertise to a differerent engineering profession.

10. Willingness to take risk -- and there is always risk with capital investment -- in an industry where the current industry structure now permits cost inefficiencies in this area to be passed on to the customer.

This top ten list is quite a menu of considerations. Cost of diesel fuel is almost the least important of the considerations.

Another advantage to electrification historically has been the long service life of the motive power and it's comparitive mechcanical simplicity ie: less moving parts than diesel or steam counterparts. The horsepower potential is as not limited by design. The acceleration rate is potentially greater or as efficent as anti slip devices can provide. They do not require refueling stops.

Railroads, like any other business these days, are less concerned with providing good service as they are with doing more with less.  Sure, it makes great sense to provide better service, with shorter more frequent runs; but that means employing more people, and paying out more in benefits for the rest of their lives.  In short, it'll never happen, and in a way that's a good thing.  I for one am sick of paying the dues (IE pensions) of retired people, because there won't be anything left over for me when the time comes.

Datafever...As far as grade crossings are concerned, the best example that I am aware of was the Chicago Aurora and Elgin which also had a nickname, "The Great Third Rail". It had numerous grade crossings which, in turn, were located often perhaps as far as Wheaton in fairly urban areas. They had alot of freight bridge traffic which kept the line afloat for afew years after passenger service was suspended...so freight was'nt a problem with the third rail. The passenger cars used batteries, sometimes battery-generator sets to keep the lights etc on in these gaps as far as passenger cars were concerned. The same applies to the recent conversion of The former CNS&M to third rail power in a similar setting. Essentially the trains motive power coasts over the "dead" section. Some cars had stingers or poles to attach to the third rail if one got marooned in a dead spot. Third rail would seem to be cheaper than overhead constant tension catenary but perhaps the carrying potential is less than overhead...

Wallyworld, thank you for that response.  I had not thought about coasting through the crossings.

Also, isn't there technology available that allows for the electrification of only the occupied block?

Yes is the short answer although the load switching and energy savings become more complicated. Most substations going back many decades back did exactly that. They would sense an oncoming train and energize. There was a funny story on the CNS&M were for years trains would slow down over a certain section of track on the Wisconsin Division until someone realized when it was originally installed it was wired backwards and went off line when a train approached!

Another advantage of electric locos is that they have a constant weight so tranction effort would be constant relatively. Deisels have maximum traction with a full tank of deisel.

Some interesting facts from India which has had a planned electrification project for their railways for some time. They have 10,000 horsepower freight units which save $55 million dollars per every 100 kilometers annually in foreign exchange for diesel fuel. The capital cost  is .9 million for single track per kilometer and 1.45 million per kilometer for double track. Hmmm. While I know this does not paint a complete picture, it is interesting none the less. I am surprised that there doesnt appear to be any cost estimates on a U.S conversion or ROI that is recent considering the flux in oil costs...and inevitable increase in cost as production will declines over time or, at least any I could find.

Aren't maintenance costs for the track higher under wire?  You have to maintain the right of way, and the wire, and the cantery.  Whenever we get the high winds or ice and snow here the NEC stops or grinds to a halt due to down wires.  Going to school in West Texas, I would think it would be a nightmare to deal with poles and wires blowing away all spring, ice dropping lines all the time or breaking the wires.  I know all the telephone and a lot of the power lines are buried in that region because of those very reasons (I am looking at a picture right now from Arizona and there are no lines on the poles anymore).  Plus you would have to have another set of maintenance crews who could work with high voltage lines, or retrain a lot of guys to know how to deal with it (and pay more to those guys if I read my unions right), which means more benefits and retirement plans on the books, creating another snowball of expenses for the railroads.  Then there is the need to keep two sets of parts for locomotives (since not all lines will be electrified, certainly not all right away) and the loss of interchangeability if you need a sub on a branch.  Another whole set of maintenance storage materials for line replacement.  Another source to get sued over (suc as when the rocket scientist climb up on stuff and get zapped touching the lines to see if they are live). 

Don't make the mistake of trying to compare Europe and the US.  Aside from being on rails, they are not performing the same tasks over the same distances.

The issue with maintenance has been largely dealt with by the use of constant tension catenary which uses counterweights to maintain uniformity against the expansion and contraction of ambient air temperatures. The lines in Europe do experience temperature extremes and mountain passes as well as semi-arid areas. The Soviet Union is a good example of long distance electrification. I guess any addition of force would have to weighed against the reduction of same needed for diesels versus electrics. The electric departments would expand perhaps while the engine folks would be retrained or eliminated. Fueling stations would not be neccesary. Interesting point about two sets of motive power types. Diesel \ straight electric hybrids are old hat. NYC and ITRR had them. Baldwin long ago did a study for the SP on same-no big technical problem. They were going to be used in mountainous areas as straight electrics and as diesel electrics elsewhere.
