Rail Miner

Open mines, run ore carts down the line and upgrade your railway, because your carts and not your mines decide how much ore you can sell.

How to play

Dig by hand to earn your first coins, then open the coal mine. Each mine level digs one ore per second.
Ore waits at the mine until your carts haul it to town. The carts always take the richest ore first.
Buy more carts, bigger carts and faster engines to move more ore. Warehouses let ore pile up, and the smelter raises every price.
Open the next mine once the one before it is running. Gold and gems pay far more than coal. The line runs for up to four hours while you are away.

If a mine's bar is full, the carts are the bottleneck. Buy carts before another mine level.
Bigger carts and faster engines both multiply the haul, so alternate between them.
Warehouses let you bank ore when you are away or busy, so they matter most late on.
The smelter lifts the value of every ore, which makes it the best upgrade when your carts keep up.

Why is my income lower than my mines make?: Carts can only haul so much ore per second. The top line of the page shows how much the carts can move.
What happens to ore while I am away?: Your carts keep hauling for up to four hours, and any extra ore waits in the warehouse up to its limit.
Is my progress saved?: Yes, automatically, in this browser on this device only.
