Ships will always be more efficient than rail per ton-mile, especially for long distance.
The number of trains (locomotives and rolling stock) / fuel (coal, oil, water) / track time needed to move the content of an average steamship convoy across the world's largest continent on the Trans-Siberian Railway would be "substantial."
In addition, there is the unloading / re-loading time-effort and then the "cost" to move "empty" trains back to the east coast of Siberia to receive additional freight.
As tragic, wasteful and huge in sacrifice and misery as the Russian Convoys were, they were "efficient." (And remember, the vast majority of Axis forces were dedicated to fighting the USSR)
