Possible future Amtrak wire train ?

[blue streak 1]

The Denver contractor has brought in an Italian wire train for the electrification of the commuter rail to Denver airport.  It is claimed to be able to string wire 4 times as fast as present equipment.  Does anyone know what Amtrak's wire train(s)  look like ?  Here is a link to a picture.  

This type equipment may be able to string the replacement CAT for Amtrak faster ?

I have no idea of what Amtrak uses for a wire train or it's efficiency.  However, the article mentions 4600 feet per day for the Italian equipment - to me that doesn't sound especially fast, but I have absolutely no experience with hanging wire.

Here's a video of a Swedish wire train in action. The caption states that they manage 2km (6548') per day.

Could Amtrak borrow this for the NYC-DC stretch? It's a little faster than the Italian variety.

Gotta love railfans.   ;-}

See here for the news (from September 2012) regarding what Amtrak chose for constant-tension wirework.  (You may need to enable 'issuu' temporarily in your browser to view it.)  I do not know the details of how Amtrak handled the contract specs for constant-tension, or who the other bidders were  -- but this was the result.

To my knowledge, this is still what Amtrak will be using to implement CT cat going forward.

Notice that the Amtrak wire train is of Italian origin too. The wire train in the Swedish video I linked to is built by Plasser & Theurer in Austria.

42 route miles with 4 and sometimes 6 tracks means ~ 175 track miles to be constant tensioned ? Since old wire will probably be replaced 2 machines one to remove and another to install will be needed.  Cannot imagine that replacement will be any less  than 3 - 4 times as long being 4 tracks ?
