https://ar2019.rzd.ru/pdf/ar/ru/performance-overview_analysis-operating-results_transportation-logistics.pdf provides Russian Railways' 2019 operating results.
Russian Railways uses cargo weights as the main metric whereas American railroads prefer units (the difference itself pointing to the differing natures of their operating models), but clearly Russia's rail network is vastly more commodity-centric. And given its high market share, total containerized traffic in Russia must be substantially lower, in total and as a share of freight, than in the US. So then a substantial explanation for rail modal share differences between the US and Russia is that much of the cargo traffic that trucks haul/specialize in is simply less present in Russia.
