Thanks for the information.  The pictures of the line make it appear to fully electrified. It would seem practical if you really have a number of guys on the ground to blow up a few power poles here and there, bring sections of track on various lines to a halt, then go hide out again for a while as the other guy tries to fix his transportation mess.  Then do it again.  They can't have enough troops to patrol all that 4,000 miles, so another use for their drones, maybe it is even beyond them. Too bad they haven't come up with a way to interdict Iranian drone shipments.

That part of the line is fully electrified. Further east the line is not. Indeed you can bring down some parts of the catenary and wait for somebody to repair it. It is better to just blow up an autotransformer station if you can, because they are much harder to replace than simply fixing the catenary. In many instances the autotransformer is decades old and there are no spares available. It can be replaced with a "modern" one but that often requires site engineering and all the associated delays. Of course, bringing down the bridges would be ideal but probably requires more time, explosives, and skill than is available.

Thank you for the name of those boxes.  So would you rather have electrified line or non electrified line in a war zone.  I suppose you could run regular diesel electric engines and forget about electrification, but do you have enough rolling stock.  Lots of issues for such a big country have to try and manage with such a limited population who can do it.
