Bloodwolff

An idea for a rail tracks, for example a mine cart with tracks you lay down like in minecraft and also a surface train track system and have a mobile base on the train/carriage/freight carriage. Different tiers. Tier 1. Lever activated cart - requires stamina to use the level to move. Tier 2. Steam loco - requires water and coal. Tier 3. Electric loco - requires power ie. batteries or solar powered. Also mounted weapons and armour upgrades. Can also pull freight carriages to carry huge storage of resources etc.
