Train Metropolis as an idle clicker game that puts you in charge of a railway company. Assign trains to run between different city districts, transporting the goods and passengers those districts need in order to upgrade to the next level. As each district levels up, you'll need to provide more and more goods and passengers. Buy an ever increasing fleet of trains. Upgrade your trains to maximise profit or growth or both! Or just click your mouse like crazy to jam as many passengers as possible onto already overcrowded commuter trains!Train Metropolis is also a city builder in disguise! You don't directly place the roads, buildings and rail tracks. Instead you expand your city by adding ever more districts and choosing their upgrade paths. How you connect those districts via your network of trains will transform this quiet backwater into a heaving metropolis!
