How fuel, heat, steam pressure, carriage insulation and carrying weight interact.

Eden Engine

Eden Engine

Burn fuel to generate heat for movement and carriage heating. Logs and branches are plentiful fuel choices. Open the heat valve so heat reaches the locomotive.

Throttle and pressure

Higher throttle produces more power but consumes steam pressure faster. Follow the consumption gauge and keep the throttle in its efficient range. If pressure falls, check fuel, heat transfer and throttle together.

Brakes

Engage the brake to stop the train before leaving it to scavenge. A stable stopping point gives the crew a clear place to return.

Carriage heating

Place heaters and maintain heat in the Eden Engine. Heaters warm enclosed spaces; open doors and damaged walls let warmth escape. Close and repair the enclosure before expecting reliable heating.

Cold

Cold causes progressively worse status effects and wears clothing down. Return to a warmed space to recover warmth. Clothing helps, but does not replace a heated refuge.

Encumbrance

Inventory contents have weight. Excess loads slow movement and drain stamina. Leave carrying capacity for the supplies you actually need, and unload before a long trip on foot.

Durability

Using equipment consumes durability. At zero it becomes unusable until repaired. Check essential tools before leaving the train.
