In A-Train 9 V4.0 you can build your own railway network complete with trains, stations and businesses. Unlike other transport sims, A-Train encourages you to take a long term view of your network, building a demand for your services by connecting new areas of the map. Your cities will grow as you improve their connections.
In this new version of the game you can actually step inside the cab of the trains you control and see what the world looks like from the footplate. There are also lots of new features allowing you to micro-manage your trains to the highest degree possible.
