From Press Release:
STOCKHOLM — APRIL 28, 2026 — Paradox Arc and Channel 3 Entertainment today released the Rails and Reactors update for Foundry, introducing trains, large-scale modular buildings, construction drones, and more.
Foundry is a first-person factory-building and automation sandbox set in a beautiful, procedurally generated voxel world. Players build and optimize advanced robot factories, mine and harvest resources, automate production lines, and manage increasingly complex systems as they research their way to becoming the galaxy’s leading robotics megacorporation.
The Rails & Reactors update introduces trains, a long-awaited feature that allows players to transport massive volumes of resources efficiently between distant bases, unlocking entirely new logistical possibilities. From small end-to-end lines to complex multi-track rail networks, the update got it all covered.
Also included is a new late-game power system: the Xeno Power Plant. This modular complex consists of five interconnected structures and can generate up to 360MW of power. Fueled by newly introduced Xeno-Crystal-based materials, it enables a significant leap in energy production for advanced factories.
Additionally, the update brings a construction drone that allows players to build from a top-down perspective, alongside new assembly robots and a modular casting machine, further expanding automation and production capabilities.
