Jun 22, Vladivostok - Moscow costs 60k roubles or around $900 first class (СВ), just looked. Second class (Купе) on less-posh train costs 17k roubles or around $300. I expected it to cost more frankly, given how second class Moscow-SpB sets you back $50 for just one night. But obviously you would want to change trains / get off at some places in between, which needs more complex calculations.
