Space Age Railway Expansion: Nuclear & Fusion Trains + Rolling Stock

by craig_g

Not another vanilla train reskin, we have our own Custom Model. Expands Space Age railways with a Nuclear Locomotive, Fusion Locomotives Mk1-Mk5, dedicated propulsion cells, higher-capacity cargo and fluid wagons, upgraded storage tanks, Train Roboports that recharge from the train’s propulsion fuel, train equipment grids, additional fluid pumps, upgrade planner support, native upgrade progression, configurable tiers, 256-direction graphics and optional HD assets.

Changelog

Version: 0.0.18
Date: 2026-09-22
  Features:
    - Updating to 2.1.20 caused load failure. This resolves it.
    - Factorio 2.1.20 compatibility: updated item fuel definitions to use the new fuel_categories API after removal of fuel_category.

    - Check your mod settings, I found mine had switched back to their defaults
Version: 0.0.17
Date: 2026-09-19
  Features:
    - Added each new train/cargo wagons/fluid wagons their own Minimap Representation.
Version: 0.0.16
Date: 2026-09-18
  Features:
    - Increased Stack size of Cooled Fusion Locomotive Cell from 1 to 2
    - Increased Recipie for Cooled Fusion Locomotive Cell produces two Cooled Fusion Locomotive Cell per craft for the same ingredience.
    - Reduced Fuel Density for Cooled Fusion Locomotive Cell from 30GJ to 15GJ - be aware this does seem to change the amount of burner fuel in the train also.
    - Removed Barrel from craft for Cooled Fusion Locomotive Cell - now just accepts fluoroketone-cold
    - Removed Barrel from Spent Fuel Reprocessing - now just ejects liquid fluoroketone-hot

    - Increased Stack size of Cooled Fusion Locomotive Cell from 1 to 2. It has always bothered me nuclear fuel in vanilla stacks to 1 and it makes creating fuel interrupts a pain. So I have increased the stack size, and halfed the desity so we not gaining more total energy for the train but gain better train interupts compatability.

    - Event-driven custom Train Roboports -- Experimental. Added experimental Train Roboports Mk1 and Mk2 for Nuclear and Fusion trains, providing cargo-wagon construction coverage with stop-only recharging. Due to the high energy density of Nuclear and Fusion fuel, Train Roboports draw their recharge energy directly from locomotive propulsion fuel. Protected fuel reserves prevent the system from exhausting the train: Nuclear locomotives retain 3.2 GJ of active fuel plus one untouched 8 GJ spare cell (11.2 GJ protected reserve), while Fusion locomotives retain 12 GJ of represented fuel energy. Recharging only occurs when the full required amount can be supplied without crossing these reserves.
    Train Roboports is completely event driven. Only when a train with a Train Roboports stops does any processing happen. Ever other train is ignored.

    - Update Logicis rocket capacity to 50 for Mk2 and Mk3 Pumps. Currently they are defined by ingredience weight. I am hardcoding these to match vanilla 50 rocket capacity.

    - Provided a full set of pump tint masks to better support unloading trains. Previously the mask only really covered a pump between pipes. This should not provide better tint coverage.

    - Added local support for the following languages
      de — German
      en — English
      es-ES — Spanish (Spain)
      fr — French
      pl — Polish
      pt-BR — Portuguese (Brazil)
      ru — Russian
      zh-CN — Chinese (Simplified)
Version: 0.0.15
Date: 2026-09-12
  Features:
    - Add Mk2 and Mk3 pumps. The storage tanks and fluid wagons now contain so much fluid we need a better way to get them in and out of storage or trains.
    - Mk2 pump x2 vanilla - cost in line with fluid tanks ingredience. high energy cost
    - Mk3 pump x3 vanilla - cost in line with fluid tanks ingredience. higher energy cost
    - Pumps unload with fluid tanks or fluid cargo wagons research.
    - Remove pictures that are not being used. (clean up)
Version: 0.0.14
Date: 2026-09-11
  Features:
    - Increased the crafting time of Cooled Fusion Locomotive Cell, Spent Cooled Fusion Locomotive Cell and Nuclear Propulsion Cell from 1 second to 35 seconds.
    - Increase the crafting time of Kovarex Axial-Flux Motor from 10 seconds to 25.
    - scale crafting time of fusion trains, each mk* gets a higher crafting time. Each requires alot of Kovarex Axial-Flux Motors, they still take longer than the crafting time for the trains they are needed in.
    - Mk1 Fusion train - Crafting time 30 Seconds + direct upgrade recipies also now matches this crafting time
    - Mk2 Fusion train - Crafting time 50 Seconds + direct upgrade recipies also now matches this crafting time
    - Mk3 Fusion train - Crafting time 70 Seconds + direct upgrade recipies also now matches this crafting time
    - Mk4 Fusion train - Crafting time 90 Seconds + direct upgrade recipies also now matches this crafting time
    - Mk5 Fusion train - Crafting time 110 Seconds + direct upgrade recipies also now matches this crafting time

    - Provided an optional link to my simulation mod to add a start menu simulation which inclusdes spage-age-railway-expansion items.
