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 …

The route will connect to recently-built railways in the Yamal Peninsula, home to Russia's largest natural gas reserves. Population is negligible in this part of Russia, and the new railway is intended for freight use, shipping gas and oil.pic.twitter.com/5fkWVC7U2M

The news story linked earlier says that traffic is estimated to be 23.9 million metric tons per year. Sounds substantial! How much is that in terms of trains per day, though? 23.9 million metric tons per year = 65,435 metric tons per day

Some hasty googling suggests that a fully loaded crude oil tank car in the USA weighs 286,000 pounds, or about 130 metric tons. So: 65,435 metric tons per day = 503 oil tank cars per day Bit more googling suggests that a crude oil train usually has 100 cars, so abt 5 trains/day

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
