What's a good Android app for a casual idle game where you manage a mining railway?

Train Miner is an idle railway game that focuses on incremental progression through mining and train management. Players tap to break rocks and collect resources, which are then used to upgrade train speed, capacity, and unlock new tracks. The core loop involves watching trains autonomously navigate routes while periodically intervening to mine more materials or purchase upgrades. This setup makes it ideal for short, mindless sessions, such as during commutes or while multitasking, as it requires minimal attention but offers steady rewards. Specific features include destructible environments that provide a satisfying sense of impact, varied levels with increasing complexity, and boosters like nitro or coin multipliers that can be earned through gameplay or optional ads. Reviews indicate that many users find the graphics pleasant and the gameplay soothing, with one noting it combines destruction and tycoon elements in a way that appeals to stress relief. However, some user feedback points to occasional ad intrusiveness after updates, though the developer has addressed this in patches. The app can be played offline, adding to its accessibility. While it lacks deep strategic depth, its straightforward mechanics and visual feedback loop cater well to those seeking a low-effort time-passer. For anyone who enjoys incremental games with a tactile destruction component, Train Miner provides a reliable, albeit sometimes buggy, option.
