US train companies are allergic to capital investment. Essentially no electrification, limited double tracking, passing sidings too short for the 2 mile+ freight trains, and essentially no alignment upgrades to increase running speed. Then we put a precision scheduled railway (PSR) operational model on top of it which incorporates none of these words => basically freight trains move ad-hoc when they are ready. This is why Amtrak service in the west can be 18 hours+ behind schedule.

In Russia, the entire Trans-Siberian Railroad is electrified and almost entirely double tracked.
