Russia sees extremes of both heat and cold. That may play a part in deciding to use separate rail piece.

- int_19h 4y agoI don't think so. It was all separate historically up until 1960s, but then gradually updated to continuous as budgets allow. Thing is, even aside from passenger comfort, you also get about 5% less friction from CWR, which translates to more fuel efficiency. And 5% might not sound like much, but when most freight cargo goes by train, and distances are in thousands of kilometers, it adds up pretty fast. Ditto for reduced maintenance on the tracks themselves, which is especially handy for those long tracks going through largely empty areas.
