Lots of other things—natural gas or turbine prime movers, regenerative braking—could be done for a fraction of the cost, if emissions is your worry.

I think it will be an interesting discussion when the time comes—soon—to reconstruct the Metra Electric overhead.

Electrification isn't a net cost at all since as long as a line carries a reasonable amount of traffic, any short term start up cost is canceled out by the long term savings in fuel cost. So for frequent urban or commuter transit service, it's the better option regardless of any other benefits.

You have NO IDEA [ NO IDEA ] of what you're missing out on, my favorite is the "Star Chart", the Most Absolutely Bestest Toy in The Whole Darn Universe. Through GPS and internal Gyros, wherever you aim the phone - it shows the Stars and Celestial Objects (with names), even pointing straight down at the ground.

Electricity isn't free. Even if it's a couple of cents cheaper than diesel or gas per thousand BTU or per megajoule, the overhead will need to be replaced hundreds of years before the capital cost of electrification could ever be recovered.

Nouvellecosse Oct 19, 2014 1:45 AM

No it's typically recovered anywhere from 10-30 years depending on how busy the route is and the electricity prices.

^What sources may I examine that will support your figures?

this is all good for you, but metra needs additional fare collection options. i may be willing to buy a specific device, such as a transponder for toll payment, for that purpose, however i feel that riding public transit and purchasing a smartphone are mutually exclusive.

OF COURSE Metra needs several different options, besides smartphones; maybe even different options for different Lines.

Briefly le_brew, what do you have against them? (one doesn't have to let oneself be seduced into it continously -- and they are very, very useful information sources, besides making calls).

Regarding electrification, the environmental and operational costs are secondary. The main benefits are reduced trip time and better ride conditions due to acceleration and improved air quality for passengers.

Kind of obscure, but good news from CREATE - the massive 75th Street project just completed all environmental reviews and was approved by the Feds. The project includes demolishing almost 30 homes for a new Metra flyover, so approval is great news. It also includes two additional flyovers, track reconfigurations, signal upgrades, and viaduct replacement.

Still no funding for this thing, but hopefully IDOT can find money for design and land acquisition.

I've seen several electrification cost benefits anaysis over the years, not sure how many of them are online. The basic enconomics are explained in here which explains that when there is fairly high train frequency, electrification is supported on an economic basis. It looks like the economic case includes not only fuel savings but also things like greater reliability and reduced maintenance costs.

I believe the recent GO electrification study is also available online.

It is. Cost estimated at $1.8 billion, possible savings of as much as $18 million per year. That's a 100 year payback period, even if you assume the money is free, with no opportunity or borrowing cost.

The time savings? For the longest lines . . . .
"between 5 and 10 minutes per trip."

Maybe there would be less expensive ways to save 3-7% of running time.

How Metra’s New 30-Year Plan Could Reshape Chicago Regional Rail

One of the more salacious details to come out this year about mismanagement at Metra, Chicago’s primary commuter regional rail agency, involves a job applicant with no particular qualifications.......

Madison/Wabash
 
I posted this originally on the Chicago development thread but was told that this would fit much better here (I didn't know this thread existed). But does anyone know the exact date when the Madison/Wabash demolition will begin? I heard spring 2015 then early 2015. Honestly I wish that the station house would be restored since it's still possible.

There's really nothing worth saving. It's a mess of pigeon shit-covered beams and a lame Neoclassic facade that has all the depth and richness of a theater set:

With a proper restoration though, it could look like this...

I mean it is the last remaining house of the original Wabash stations. About a month ago, I went down to photograph the entire stop and while it was in bad shape, I've heard from a few different sources that it's structurally fine. That's the last of it's kind and honestly it has some unique personality.
