Player-built trains with stations and cargo cars

Give rails a real purpose beyond short mine runs.

- Craft a locomotive plus attachable cars: passenger cars you can build and decorate inside, and cargo cars that carry chest inventories.

- Place a station block to define stops along a route, and let trains run player-laid track between bases over long distances.

- Redstone controls schedules: a train departs on a timer, on a button press, or when loaded with cargo.

- Fuel the locomotive with coal or other fuels, so long routes have a real operating cost.

Minecraft's rail system has been a dead end for years. Trains would turn it into actual infrastructure you plan and build.
