Reading about a new railroad that just began construction in Russia and it got me thinking about freight traffic in tons vs freight traffic in trains:http://www.railwaygazette.com/news/infrastructure/single-view/view/construction-of-northern-latitudinal-railway-to-start-in-2019.html …

Presumably, Russian tank car sizes and train lengths might be different--and this back-of-the-envelope estimate is only based on oil, not on natural gas--but I expect my hunch that heavy freight traffic doesn't necessarily mean lots of freight trains will still be true

What if this railway had been built in a heavily populated part of Russia instead of in the frozen north? With adequate signals and good scheduling, 5 daily freight trains shouldn't pose any serious obstacle to frequent passenger service.

This lesson must be taken to heart in the USA as well, where there's a lot of friction between freight railways and passenger interests--you don't need to be each other's enemies; both of you benefit from expanded and modernized infrastructure!

I think something is not right... Did you take the weight of the contents or the whole car? Because a Russian tank car can hold 66t while a full train - 4158t. So you need 16 trains per day. A single track line can accommodate 22 pairs of trains.
-
ahh, good catch--I was looking at the weight of the whole car, but the 24m tonnes/day is prob only talking about the contents
-
Single track line can accommodate far more (or far less!) than 22 pairs of trains, though, depending on a variety of circumstances
-
This is something I've always wondered about: train weight? track quality? what are the variables?
-
Presence or absence of sidings, signalling system, train speeds, train lengths, track quality--those are the ones that come to mind immediately
