My point about the CAT is that some passes there is no CAT movement others have some mainly up and down.. I do not understand the math of catenary. The power companies have to deal with it ongoing from local lines to major high voltage lines. It is apparent that PG&E did not understand it enough and had many fires caused by the lines contacting burnable fuel in California.
Back to Amtrak. It is well known that the PRR style CAT has problem if an EMU train has too many PANs that bounce can cause problems.. All the Acela-2 passes have just one pan up. I am still uncertain if one pan can supply both locos or if the one loco is able to push or pull the whole train ?.
Yes, a wire harness in the Acela II sends power the length of the train to the trailing locomotive. If the front pantograph fails, it can raise the trailing one and use that. The trucks are also interesting; it's a more unified trainset than the old Acela (see the video below).
As for the catenary, this Amtrak manger goes into great detail at 1:08:
The video was posted on these forums recently by Mass Bay RRE. There are two types of cat on the NEC. And the Amtrak manager doesn't see that changing.
