Here is small preview of the game and some key features (I'm not so good in English so I've just copied this text
from official game page. Sorry )
"Who of us didn’t want to build our own railroad as a child? With forks, intersections, bridges and tunnels, stations and houses, different trees, factories and windmills! Now you have plenty of opportunity to play with all types of trains in a great railroad manager Train Valley. You will have 24 levels to connect stations into a single railroad system and make sure that trains reach their destinations without accidents and delays.
True railroad romance for train enthusiasts of all sorts!
