No way ... not in million years

My ISP is Comcast ... judging by some of the monumental screw-ups I've seen on some of my bills, I wouldn't trust Comcast except to royally screw it up on a regular basis.

Yes, it is MPLS. And you can get to the article if you are running Adblock software in your browser.

Hacking train lines

okay what I do not understand from the article is, are the switches controlled remotely or is the GSM for somehow allowing the trains to talk to the switches directly? if its just for controlling them from a train control tower of some kind id imagine they could convert to wired control if needed.

Re: Hacking train lines

can't they use the track as a data bus? Like how DCC works for Model Train Sets?

Re: Hacking train lines

I imagine relying on the track being in good enough shape for any substantial distance (ie: no breaks in the rails. Can be enough to open a circuit but not enough to risk derailment) would be the biggest issue of that. Most electrified rail systems have power substations at so much distance along the tracks powering a small section rather than the whole thing. For electrified rail it could be pretty easy with some BPL-like system. Traditional non-electrified systems on the other hand...

I swear, some people should have pace-makers installed to free up the resources. Breathing and heart beat taxes their whole system, all of their brain cells wasted on life support.-two bit brains, and the second bit is wasted on parity! ~head_spaz

It's already being done, Automatic Train Control (ATC) uses signals sent down the rails to operate indicators and controls in the cab, other track signals are used to operate trackside signals and crossing gates.

This is an ATC pickup coil mounted underneath and just behind the plow on an locomotive.




This is the ATC in-cab readout within the same locomotive.
