Changelog

Version: 0.9.0
Date: 2026-11-03
  Features:
    - Accumulator wagon: its own rolling stock, with the accumulators in its recipe, drawn with its own art on flat and elevated rails. Five bars on it show its charge, and clicking it shows the exact amount. Its charge is lost if it is mined or destroyed. Two fit in a rocket.
    - Arc tower: needs only the electric network. A charging tower fills the nearest stopped wagon beside it, drawing power like a machine so accumulators can feed it. Rotate it (R) and it unloads the wagon into the network instead, supplying power like a generator, so it charges accumulators and can restart a dead network. An arc jumps between tower and wagon, and alt-mode shows the charge and rate.
    - A tower faces the nearest rail, and glows blue (charging) or yellow (unloading) from every side.
    - Towers within 13 tiles of each other always agree, and one train is never charged and unloaded at the same time, so towers can't fight over a wagon.
    - Train wait conditions: the wagon holds "Wagon charge" items, one per 1%, so use Cargo full, Cargo empty (under 1%) or Item count of Wagon charge.
    - Technology "Power logistics" (red, green and blue science, after advanced circuits).
    - Settings: wagon capacity, tower power, charging efficiency, and whether a charging tower draws like a machine or only takes surplus.
