Rebel Without a Charge

My friend Mr. Setty sent me a link to English Russia about a month ago with a copy of this photo asking for a caption. The original post is an interesting photo group of electric trucks with overhead wires. My first thought was the title to this post. What comes to your mind when you see this picture?

Louisville's Third Rail

Apparently Louisville Kentucky had elevated electric rail service in 1886, remnants of which still remain today.

Muni LRT to be Powered by the Sun

Calgary powers its light rail with wind, Seattle with hydro and Muni which was partial hydro, will now be solar. So much for those coal fired power plant arguments against light rail and future energy.

The photovoltaic systems at the two facilities and the solar energy they generate will be developed and operated under a "Power Purchase Agreement" between the SFPUC and Recurrent Energy. Under the agreement, which the SFPUC members authorized SFPUC staff to negotiate today, Recurrent will finance, design, build and operate the solar energy projects and provide all the energy generated to the SFPUC for a period of 25 years. The five megawatts generated between the two facilities will be used to help power other San Francisco public services and buildings, including streetlights, San Francisco General Hospital, Muni light rail and city schools.

The Gasoline Conundrum

For every one of these stories...

When does the price of gasoline get so painful that drivers park their cars and look for the nearest bus stop or rail station? Many in North Texas say that time has arrived. And a new study of driver attitudes – plus increasingly crowded buses, trains and station parking lots – suggests they may be right.

There is one of these...

High gas prices are pushing more people onto buses and subways, straining transit agencies trying to meet the demand.

Like other consumers, the agencies are also paying more for fuel — 44% more this year than last, according to a survey of 96 transit agencies to be released Friday by the American Public Transportation Association (APTA).That double hit means bus and train operators are raising fares, cutting services and delaying improvements. Almost half of bus operators and more than two-thirds of rail operators have increased fares. About a fifth are cutting service.

These aren't choices we should have to make and its unfortunate that our the majority of our transportation system is tied up in oil. It'll be interesting to see how resources shift as prices go up. Will fund transit with higher fares as some have already started to or will it come out of a budget for new roads. The paradigms are shifting, but perhaps not that much.

For the future, when the grid starts to get changed into alternative energy like solar, part of the capital program for smaller cities might include provisions for electrification of heavier ridership bus lines. Now that oil and diesel prices are so high, it's possible to pay off some of the capital cost over time of this incremental improvement. Since this would include some smaller cities, it would be a great opportunity to include more areas into capital funding programs. It certainly would make more lawmakers happy that they are serving their constituents and make available funding from a carbon economy.

Dubai to Install Alstom APS

Interesting news on the International Tram front. Dubai is going to build a 10 km (6.2 miles) tramway with 13 stations. But that isn't the interesting part. Alstom, who owns the rights to the catenary free APS ground level electrification system, has started moving it outside of France. Bordeaux is the only city currently to operate the system. However other cities such as Angers have begun looking to install it. It will be interesting how the technology fares in the sun soaked middle east.

Many have hoped that the technology would come to the United States and answer the call to get rid over overhead wires, specifically in the District of Columbia where an old law prohibits wires. It was specifically called for by Clay Chastain for Kansas City's system. However experts in the US have said that Alstom has no plans to bring the system to the United States. Part of the problem is the unknown effects of stray current coming from the third rail when the roads are salted during snow or ice storms.

How it works: Basically a third rail is laid between the two tracks and turns on when radioed by the vehicle. Two shoes, one on each end of the tram take up power as the electrified sections pass under. Sections only turn on when they are underneath the vehicle leaving pedestrians safe from being electrification.

Outside of the historic downtown, the line in Bordeaux switches over to catenaries. Other cities are looking into using batteries and Stone Consulting that brought us the Kenosha Streetcar for $3 million per mile is also looking to use a ultra-capacitor for a heritage line in Savannah Georgia.

Holiday from Real

Why can't we have a real discussion about energy and alternatives in this country? As we continue to talk about worthless alternatives like gas tax holidays and price caps, real solutions to our energy problems get tossed aside. Today Thomas Friedman writes in the New York Times that the United States passed on giving tax breaks to alternative energy. Soon we will have tax credits for oil companies that are making record profits on the market while alternative energy credits run out. While this would not really help in the transportation sector that uses the most oil, it most certainly would have the effect of getting the ball rolling on ways to get us off the sippy cup. Even carbon taxes as Ezra Klein points out would help give us a push.

But there is another problem that plagues us now and long term. The Gizmo Green. This is the hope that technology alone and not also behavioral modifications will save us from ourselves. Barack Obama even has an ad out discussing what we can do including:

Raising fuel efficiency standards
Alternative fuel research
Middle class tax cut

Whew. Once we do that the problems will be solved! Not. That is all about cars. What about modes of electric transit? What about development patterns? Walkable, bike friendly communities? Anyone? Bueller?

Matt at track twenty-nine says it best:

Still, Mr. Obama's message leaves a little to be desired. He recently reiterated his support for Amtrak and for building a better high-speed rail network in this country, but he has not yet asked Americans to change modes, nor has he promised to significantly change the way we build transit in America.

In all of President Bush's States of the Union, he called for us to reduce our dependence on foreign oil. Not once did he ask Americans to try the bus. Not once did he promise a spending package that would start a wave of new transit construction across the nation. Instead, he called for new fuels (to be delivered sometime in the future) and a switch to biofuels (also to be delivered sometime in the future).

Asking Americans to switch to transit would produce an immediate reduction in oil usage, especially if it was coupled with subsidies to reduce fares and the construction of new lines.

Seems to me we did this with the Interstate Highway Act. Not to mention that more transit means more jobs in an ailing economy. Perhaps a new program is in order to change our possible transport and neighborhood choices, not just what powers our cars. Now when buying your first house, you can choose between suburbs. It's annoying to hear folks say that the market prefers suburbs when downtowns are so expensive because of the market for living in them. I wish those people that hated living here in dense ole San Francisco would move out because its dang expensive due that pesky market demand for a transit-oriented lifestyle people sure don't like.

Overhead Wires, Pantographs, & Trolleypoles

Warning, rant approaching:

Ben Wear from the Austin American Statesman wrote an article on his blog today on the proposal for an Austin starter line by Roma design. In the article he muffed the overhead wire, not my blog, but the technology details.

Light rail, as opposed to the commuter rail opening late this year or early next year, is generally powered by electricity and has a system or overhead wires that connect to devices on the top of the cars called “catenaries.”

Sigh. The devices on the top of the vehicles can be two things, Pantograph or a Trolley Pole, just like my nom de plume. Interesting history point, the pantograph was actually invented by none other than the east bay Key System, now AC Transit, which had it's 50th tear down anniversary last week. The catenary is actually the support wire for the electric wire. From wikipedia:

To achieve good high speed current collection, it is necessary to keep the contact wire geometry within defined limits throughout the length of the overhead line. It is usually achieved by supporting the contact wire from above by means of a second wire, known variously as the messenger wire (US & Europe) or catenary (UK & Canada). This wire is allowed to follow the natural path of a wire strung between two points, which is known as a catenary curve, thus the use of catenary to describe this wire or sometimes the whole system. This wire is attached to the contact wire at regular intervals by vertical wires known as droppers or drop wires. In this way the contact wire is effectively supported at numerous points.

The messenger wire is supported regularly at structures, either by means of a pulley, link, or clamp. The whole system is then subjected to a mechanical tension. The messenger wire is usually pulled slightly to the left and right by successive supports, so that the contact wire slides from side to side(stagger) on the pantograph as the vehicle moves along (if it did not then it would tend to wear a groove in the pantograph's carbon insert). Such a system, with a single supporting wire, is known as simple equipment.

Sometimes we also call simple equipment a trolley wire which is much more aesthetically pleasing and should be used in downtown settings to minimize the visual pollution. I know this is a bit picky, but if you're going to continuously pick on the local transit agency on details, at least get yours straight.

Rant off.

Transport Electrification

There is a lot of talk here of passenger rail but little discussion of freight. I can't say that I know about the business that much but I wanted to share a few ideas that I had seen that look promising.

The first is a plan thought up by Bruce McFadden over at Docudharma. His idea is to create a backbone energy corridor along freight lines to transport stranded wind.

It should, I hope, be clear that much of the best resource is in areas that do not have the highest electricity consumption. And at the same time, that is a lot of the terrain that the transcontinental freight rail must traverse to get where its going. And, at the same time, we desperately need to get the main freight rail trunk lines electrified, by hook or by crook. Ergo, I got a grossly oversimplified policy proposal to present.

• The Federal Government invests in publicly owned infrastructure to electrify the main railroad
• In return, the owners of the right of way cede use of the right of way above the part that they need to public use, together with access to the ground level right of way for support structures
• That right of way is used to establish long distance High Voltage DC trunk lines to bring sustainable energy from the places that have it to places the need it
• In areas where there is a commercial wind resource, the usage rights above those trunk lines are available to be leased out for wind farm operators, with the lease payments rolled back into the funding for the program

Some answers to some challenges to the proposal, after the fold.

Another of interest is a plan to reduce energy consumption in 10 years through transport electrification, mostly by electrifying the freight lines by granting property tax waivers for railroads that electrify. It also includes more rail transit and trolleybuses. Alan Drake discusses that plan over at Light Rail Now! I'm not sure how feasible it is, but its an interesting idea to ponder.
