Trax Siemens Debut

Ok so two posts on this is a bit much but I wanted to compare the Charlotte and Utah vehicles side by side. These are for you Gordon. It looks as if the UTA vehicles are even shorter than the Charlotte LRVs and much shorter than the Houston LRVs which are all the same series. I had read before that this was done to accommodate four car trains.

New Siemens S70 LRV Debut in Salt Lake

We discussed these bad boys when the order was put in back in 2008. The thing I find interesting about this version of the S70 is that they are snout nosed and less archy on the ends than the new Portland and San Diego vehicles. This apparently was so that they could continue to run four car trains.

Here's a photo of Portland's new LRVs (with some older)

Then the new Salt Lake City version

I think I actually like them better. If anyone in Utah gets some photos shoot em over and we'll post them.

Temporary Switch

I'm a fan of Veke on facebook but most of the time I have no idea what they are talking about because Hungarian to English translation leaves much to be desired. But I enjoy their work covering trams in Budapest and other Hungarian cities. So it was kind of cool to see how an emergency tram switch would be employed when a section of track was closed due to what I believe is some sort of flooding. While they fix it, this ramp allows trains to move forward without having to dig into the track surface. Check out the blog through google translate here. Also check out the youtube video below.

When Fitness Centers are Like Catenaries

I never understood why developers waste their time building fitness centers or other extras no one really uses. I wouldn't want to pay rent for that. Seems like they might start to figure out that gold plating isn't getting them where they wanted to go. So who thinks that LRT needs to go through the same de-goldplating process?
“The frills are coming out,” said Tim Colen, executive director of the Housing Action Coalition, who advocates for housing in the city. “No concierge, no fitness room, and much smaller units. These are the coping mechanisms for the new era we’re in.”
And in light rail world, the quote would look like this:
“The frills are coming out,” said Some Guy, executive director of the Rail Construction Coalition, who advocates for transit in the city. “No rebuilding curb to curb, no gigantic catenaries, and much smaller station designs. These are the coping mechanisms for the new era we’re in.”

New Tech & Electrification

If you were a city, would you want to be the first to implement an unproven technology whether it's hydrogen streetcars or super fast charging streetcars? I know that makes it tough for innovation but it seems like a lot of risks and on a political level it means career death if the program crashes. That being said, there are lots of interesting ideas out there that might deserve a look. In addition to the two above, the inductive motor looks interesting as well.

One thing though, I really really don't get the hate of overhead wires. They have been proven since 1888 and create no point source emissions. Get over your personal aesthetic people. If you were so concerned with wires, you should also be concerned with that smog stuff as well. As I've said before, it may look bad to you, but my lungs don't care.

On a similar note, some Railroads are considering electrification as well as allowing corridors to be used for wind power transmission. This idea has been around for a while and I'm glad they are finally catching on.

Routesy 2.0

I have to agree with Greg on this one, Routsey 2.o for the iPhone is a brilliant application. It melds together real time BART information with Muni making it really easy to get around the city. The best thing in my mind is the ability to bookmark stops you visit often. That is worth the $2.99 right there.

One of the things that we found out BART does better than anyone else is releasing thier real time data into space. Anyone can have access to it which is rare for transit agencies to be that transparent. Kudos to the team there for such excellent foresight that other agencies don't even want to even think about.

Grass Track on the T Willie?

This post got me thinking, what if they would have put in a grass track on the T-Willie? Could we do it on Geary?

Railway Robbery?

I don't know about you all, but this seems a bit like a blackmail scheme. It's like we're in Berlusconi's Italy.
A firm called AnsaldoBreda says it will relocate its assembly and manufacturing plants from Pittsburg, Calif., and Italy to Los Angeles if -- and it's a big if -- the MTA agrees to buy 100 rail cars from the firm for more than $300 million.
This is the same firm that built Muni's and Boston's LRVs. I don't think the LA versions are bad looking, but they are too heavy making them energy hogs and have continued to be a problem in the maintenance department. Perhaps an all in move to Southern California and a change in management would to the company good. Though it doesn't look like that is going to happen. Why would they do that when they should just be expanding thier Pittsburg digs.

It's kind of funny though. After all the problems they've had, what makes them think that making such a claim would even remotely be taken seriously? Maybe they'll get a deal for an American made Sirio.

Gold Line Pull

They're testing on the Gold Line Eastside Extension in LA. In the video a service truck is pulling an LRV but those new Bredas are quite heavy. Looks like the truck has some torque.

The Over Under

The East End in Houston is building a light rail line. To perpendicularly cross the freight tracks, Metro has proposed building a bridge. The neighbors want an underpass. My first question would be what happens to the underpass in the medical center when you get a torrential rain storm, something that happens quite often in Houston. Does it flood? If so, it doesn't seem like a great idea, however aesthetically pleasing. Does anyone know of other lines that have a flooding problem?

Transfer of Development Rights

I've always thought this could be used for TOD, but never knew exactly how it would be implemented. In any event, Greater Greater Washington has a meaty post on TDR.

Sand Traps

In and around San Francisco, there are places where LRVs stop and you'll see lots of sand. For a while I wondered where it came from until I talked to some folks who told me that every LRV has a sandbox under the seats behind the wheels to gain traction going up hills and on rainy days. Today in the Rocky Mountain News. One of the LRT mechanics discussed the sandbox:
It's for traction, but it's pure, high-grade sand, not salt or chemicals, according to a reader who's a mechanic on light-rail cars. "When the propulsion system detects either sliding while braking or spinning while powering, sand is dropped to increase traction between the wheels and the rails," the reader wrote.
You can see the sand on the ground here in the photo below. It's the best one I could find. (Note to self, take better pictures of the little details)

Elizabeth Avenue Video Blog

So I'm going to try this video blog thing here. My camera has the ability to take short movies as you've seen before so I decided while I was out today in Charlotte that I should do one for the Elizabeth Avenue Streetcar Project.

Initial Blog (Sorry About the Wind)



Part 2: The Surveyer




So a few things I missed. Because they were already reconstructing the street, this stretch only cost about $5 million dollars more. They also expect to be to the hospital at the high end by next month. I'll try to do this more when I see interesting things. Hopefully next time I'll write something up but on the spot seems genuine as well. Let me know what you think.

A Logic Disconnect

We discussed the moves by the Dallas Ft. Worth region to move forward with a regional transit network but some skeptics still don't understand how things work as it pertains to automobiles. In a Fort Worth Star Telegram article, the following is mentioned.

Others argued that technological improvements to cars might improve the region’s air pollution, making commuter rail unnecessary. "It’s likely that by 2011 we’re going to see a lot of electric automobiles on the road," said Dave McElwee, president of the Tarrant Alliance for Responsible Government. "Ridership will go down."

I'm constantly amazed by the technophiles that are hoping some magic electric car will rise making transit useless. The problem with this is even if you built a car like that, the roads still need to be expanded to accommodate them. Also, with the increases in VMT expected from hybrid cars making people more mobile, energy consumption still continues to rise. So while there might be electric cars at some point, mobility still creates issues. The human condition causes a problem in that for work people need to be close to each other but the dispersed living arrangement causes a need for greater infrastructure to accommodate mobility.

I also don't see what people have wrong with transit. The narrative in this country has been driving for so long by suburbanites, it discounts the feelings of urban dwellers. In places with well run transit, movement is so easy, and city life is their choice. When I was in Budapest and Vienna, I couldn't imagine having a car in that city. The Metro came every 3 minutes and urban form made all trips convenient by walking. Even here in San Francisco, I can get where I need to go easily by walking or using transit. It's silly to think about getting in my car, yet there are still car driven policies, pushed by those might as well be living in the suburbs.

McCain Cat Sez...

I can haz more trains for other countries? He lauds the GE locomotives that are built in the United States, but gosh, let's not build more tracks for them to run here.

MIT Students Hack Boston Charlie Cards

The Facebook generation makes hacking transit look easy. From the Subway Blogger:

Apparently, some students at MIT made it a class project to hack the Boston subway system (aka the T). As a matter of fact, the title of the project is: “The Anatomy of a Subway Hack: Breaking Crypto RFIDs & Magstripes of Ticketing Systems.”

Now, the students are computer security majors, so you can see the fit. They planned to give their 80+ slide presentation at Defcon, a very large security conference. However, the MTBA sued to have the presentation stopped. A judge ordered a temporary restraining order keeping the presentation quiet.

It's my understanding that Defcon doesn't have a lot of leaks. I'm not really sure what Boston is worried about. If these kids can do it, certainly anyone can if they have the appropriate skills.

Did You Know?

That neither SEPTA nor New Jersey Transit has a PDF of their complete system map anywhere on their websites. That's a good way to get new riders to transit, by making people find out which route they are on with single route maps like these. Brilliant, guys. Come on. Don't make people work so hard, it shouldn't be like that!

Streetcar Scalability and Capacity

Over at M1ek's I posted a few photos of some Combino trams from different places around the world to show how you can scale the vehicles to fit within any environment. Depending on the capacity needs, there might only use for one streetcar. However, if there are higher passenger volumes, then there are two ways to accommodate this. Either by coupling cars or modular design. Coupling cars is possible, below is a photo of the Skoda T3 in Plzen Czech Republic, the same vehicle as the Portland Streetcar, with couplers.

The next option is the modular tram. Basically, you can build to specifications you want. According to the Siemens website, they c trams from 18 to 72 meters (60 feet to 236 feet) almost 4/5ths of a football field.

Sorry for the bad picture but I stole it from Tom Furmaniak's powerpoint on streetcar tech.

Real Examples below:

This is the same for the other tram companies including Ansaldo Breda, Skoda, Kinky Sharyo, Bombardier, and Alstom's Citadis Tram.
