It does not work and is not archived. Neither are any of the pages linked in this walkthrough (http://web.archive.org/web/20140929091847/http://www.gamezhero.com:80/games/railroadshuntingpuzzle2/walkthrough) and this walkthrough video is broken (http://www.crazygames.com/game/railroad-shunting-puzzle-2). I could find no other walkthroughs or gameplay beyond c-2.

Whatever happened to the walkthrough/solutions? The link is DEAD

Also, it seems that the medal for beating the c-zone is broken. Probably because of the typo as it's "С-Zone" instead of "C-Zone". If the author arsed himself to fix this, the medal would probably work AGAIN, but NOOOO, let's keep it broken fellas!

Honestly: if somebody finished all the levels of this game with all medals without using the walthrough at all then I'll declare her/him a genius with a computer in the brain. Awesome brain twister.

I made 300 moves I think I deserve a medal 300/3 moves.

Very nice game, although it seems the tutorial is too long. It is better to have tutorial, then play a few levels, then have another tutorial and so on.
