Train Digger

"Train Digger" is a game about a mining train that goes deeper and deeper underground while a whole city grows above ground from the extracted resources. You start with a simple train and a quiet town, and eventually end up with a powerful locomotive with several cars and a bustling metropolis with roads, houses, and towers. The operation is set up as a closed loop: the train extracts stones from the mine, the kiln processes them into bricks, machines transport the bricks to the construction site, and the city grows. The trucks for transporting finished bricks operate automatically; you only need to buy more when necessary. The deeper the mine goes, the harder the rock becomes, so you’ll need to buy and combine grinding machines—this is the only way to continue extracting materials. The train keeps running even when you’re offline, so progress never stops.

How to play?

At the start, the game provides a brief tutorial. To move the train, hold down the mouse button—it won’t move on its own. The grinding machine at the rear of the train collects stones and drops them behind it; on the next lap, the train picks everything up from the ground and loads it into the cars. When the cars are full, stop the train at the furnace—it will process the stones into bricks, and the trucks will drive up on their own, load up, and transport the materials to the city. You earn money the moment the trucks unload at the construction site. In the menu at the bottom of the screen, purchase upgrades: grinding machines and their connections, train speed, car capacity, and additional trucks. Use boosters to speed up operations, and to view the entire area, tap the eye icon and swipe across the screen—the train will continue running on its own during this time.
