So...American HSR is actually happening? Here's to hoping that no one magically finds yet another reason to try to shut it down.

Thought, would it be that difficult to build a PDL over the existing ROW in the Northeast Corridor? In other words, essentially accommodating a viaduct over the existing tracks.

They might have to push some of the center tracks out, but it would be simpler than trying to build two tracks on the shoulders of the ROW, no?

Maybe it's not possible, but I was curious if it would be.

My opinion? Pretty much impossible. Not really practical from a cost perspective, and it would be an aesthetic nightmare too. And there would be tremendous pushback from towns along the route......

I'm just scratching my head now that I'm looking at it daily and wondering how on earth Amtrak is thinking of doing it. It would be one thing without all the commuter services, but it seems like they'll just end up doing intense realignments in those sections that are less than straight? Adding two additional tracks just seems like a no-no from a cost perspective (not to mention the property abutting much of the corridor makes this option almost impossible).

I've noticed they're upgrading the part of the network in NJ at the moment, and that many of the ties have been replaced (as well as doing some work for new power sources).

6 tracks isn't that needed south of Rahway , the only major issues on the NEC in New Jersey are... Elizabeth S-curve and Metropark Curves which need to be straighten , you also have 2 track expansion from South Elizabeth to North Elizabeth.

Maglev backers plan 15 minutes Washington-Baltimore trip


A prototype of the Japanese maglev train. Japan is offering $5 billion in financing to build a maglev line between Washington and Baltimore.

That's what backers of the idea -- including the government of Japan -- promise. And they're betting $5 billion that it can really happen.

In a filing with regulators in Maryland, proponents say the train would use magnets to levitate the train -- a system known as "maglev" -- and allow speeds faster than any traditional rail

The $5 billion is a down payment. Estimates range from $10 billion to $15 billion for a Washington to Baltimore maglev line.

Japan, which has just started its plans to build a maglev line from Tokyo to Osaka, hopes that by providing the financing it will spur demand for its technology in the United States. Prime Minister Shinzo Abe has been pushing his country's maglev technology in meetings with U.S. political and business leaders.

The backers of the Washington-Baltimore line, The Northeast Maglev, hope to eventually extend the line the full 225 miles from Washington to New York City. Some estimates put the cost of the New York to Washington line at far more than $100 billion.

Some high-speed rail proponents in the United States are critical of maglev proposals, arguing the money could be better spent on lower-cost services using traditional tracks.

East Japan Railway targets Californian high speed contracts
08 Sep 2014



USA: JR East is to lead a Japanese consortium in bidding for railway systems contracts for the Los Angeles – San Francisco high speed line now being developed by the California High Speed Rail Authority.

JR East announced in Tokyo that it expects to work in partnership with six other firms in an effort to export Japanese Shinkansen technology to the USA. While the prime focus if the consortium would be rolling stock, JR East is also understood to be targeting the supply of signalling equipment. The group also reportedly believes that Japan’s experience of building and operating high speed lines through areas prone to seismic activity could be attractive to CHSRA

CAHSR should adopt ECTS-2 with deployability of ETCS-3 as its signaling system.

It is the only feasible way they can avoid severe issues with vendor lock-in.

I'd prefer they go with ETCS

I wonder if its possible to have low level platform HS trains.

California has all low level platforms and on some sections they will have to share stations with Caltrain, a commuter rail in Bay Area.

i think Maglev would be the better option.

As far as I know, the association of american railroads also developped their
own version, that will be deployed nation-wide over there (I did not follow this
PTC story very closely, though). Why would this be a vendor lock-in ?

If you want low-floor trains on the platforms that purchase Talgo AVRIL: 760 mm on the rail.
When tested trains (same height as the AVRIL) in 1988 in the Northeast Corridor (120 mm) had to put up two steps to the platform from the train.

I thought Caltrain was going to move to dual-level boarding EMU trains. The HSR rakes can have retractable footboards/steps for low-level boarding as in Eurostar and Velaro trainsets.

Quite true. However, there seems to be a very small (but influential insomuch as there are few other knowledgeable voices) cabal of commenters on transit blogs that want to push low or mid-level boarding even for HSR trainsets, presumably because the existing (European) models exist and will presumably save money. The retractable steps you mention are discounted by them as being "unreliable" "prone to breakage" and the like.

I imagine it will also be necessary to have dual trains able to run on electrified routes and pathways that are not.
The Talgo AVRIL may also have hybrid version, as the Spanish 730 series or VIP train to King Abdullah of Saudi, part of delivery Haramain.

A greeting, and sorry for my bad English
