A functional train layout in Voidtrain separates high-frequency crafting and fuel storage near your engine from secondary farming, crew quarters, and decor. Because expanding wagons requires dedicated depot visits and specific refined components, building an orderly platform early prevents resource waste when redesigning your interdimensional express.
Train Car Upgrades and Building Requirements
You begin Voidtrain with a bare trolley platform and no engine. Upgrading the train to add wagon length or additional platforms is only possible at specialized terminals located in outposts and depots along the rail line.
When remodeling, dismantling benches returns only half of the invested crafting materials. Only core driving mechanics can be moved without penalty. At depots, hold T to alternate between the Scrapbook (used for placing items) and the Hammer (used to dismantle structures).
To expand to a second platform early in the game, prepare the following materials before arriving at an outpost terminal:
| Component / Resource | Quantity Required | Sourced From / Prerequisite |
|---|---|---|
| Iron Ingots | 4 | Smelter (from Scrap Iron) |
| Bearings | 2 | Laboratory (requires Grease) |
| Iron Bolts | 2 | Workbench (from Iron Ingots) |
| Springs | 2 | Workbench / Looting |
| Wood | 8 (minimum) | Floating debris (needed for wooden flooring) |
Before Phase 10, players typically expand to at least two platforms: one dedicated to production workbenches and the front platform reserved for the locomotive engine once researched. Up to 12 wagon platforms can be built over the course of the game, as tracked by Steam achievements.
Optimal Wagon Division and Room Assignments
As you progress from basic trolley platforms to steam and diesel engines, dedicated wagon cars allow you to streamline routine crafting, fuel replenishment, and defense tasks. Players on the Steam community forums have mapped out functional multi-car templates based on operational frequency.
The Locomotive (Front Platform)
The front section houses your engine and primary controls. Keeping navigation and defense gear on this platform reduces travel time during attacks and obstacle encounters:
- Engine controls and driving levers: Place these where you have clear sightlines. You can shoot rail levers from a distance using your sidearm to adjust tracks or halt movement.
- Engine fuel storage: Dedicated chests containing coal briskets, charcoal, or gasoline.
- Immediate emergency gear: Turret ammo, bandages, personal weapons, and quick-access medical supplies.
- Recycler placement: Setting your recycler close to the engine allows quick processing of salvaged scrap while driving.
Production and Workshop Platform
Keep your primary refining stations grouped closely together. Platforms function on a 5x5 structural grid, while most production tables occupy 1x1 or 1x2 footprints:
- Smelters and Foundries: Maintain smelters near your raw ore and scrap crates. Early game smelting focuses heavily on iron ingots, alongside occasional copper bars (typically at a roughly 4 to 1 ratio).
- Workbenches: Tier 1 and Tier 2 workbenches for assembling iron bolts, copper pipes, and wire.
- Laboratories: Dedicated chemical processing tables used to craft grease from creature fat.
- Resource Lockers: Position storage chests or racks immediately adjacent to the benches that consume those items.
Sustenance and Gathering Platform
Farming and fluid infrastructure can be grouped onto a dedicated mid-train wagon:
- Water Collectors and Condensers: Steam achievements track building 3 or more water condensers. Placing a water collector and a lootcatcher on your main storage car allows you to pull collected supplies directly, while additional units can sit further back.
- Garden Beds and Crop Plots: Unlocked around Phase 9 to 10 for cultivating food items such as tomatoes and peppers.
- Kitchen Workstation: Houses Tier 1 and Tier 2 kitchen setups for converting Organics and ice into refined rations.
Crew Quarters and Rofleemo Perches
Rofleemo pets are found inside cages at depots and can be brought onto your train by constructing perches:
- Perch Spacing: Perches must be spaced out across your cars (approximately one perch per two carriages).
- Rofleemo Feeding: Feeding mushrooms to Rofleemo causes them to regurgitate decor items and resource recipes into a small container below their perch.
- Crew Furniture: Beds, passenger chairs, and alien restrooms fit comfortably in the mid-to-rear cars without crowding industrial walkways.
Decor Themes and Train Aesthetics
Decor recipes unlocked via Rofleemo fall into three distinct aesthetic lines observed in gameplay:
- Raiders / Bandit: Heavy metallic surfaces and rugged workshop furniture, suited for smelters and armory wagons.
- Ship / Nautical: Wood planking, ship beds, and open layouts matching crop plots and wooden condensers.
- Luxury: Wall ornaments, carpets, lamps, bookshelves, and pianos for passenger cars.
Exterior train walls and decorative siding can only be installed along the engine car and subsequent platforms once the locomotive engine has been researched and placed.
Storage Management and Loot Collection
Item handling requires strict organization because basic storage crates do not stack on top of each other and hold stacks of only up to 5 items.
- Avoid Dropping Items Loose: Loose resources left sitting on open train flooring get cleared and permanently lost when passing through gate transitions.
- Bulk Processing: Refine raw fat into grease at the laboratory immediately, and convert scrap iron into bolts and ingots to consolidate chest slots. Do not burn animal fat as simple smelter fuel, as fat drops randomly from sharks, flying creatures, and leeches and is required for essential mechanical grease.
- Keep Moving: Stopping the train repeatedly to fish every floating resource leads to rail buffer collisions. Maintain steady forward momentum and rely on depot chests, Arena challenges, and island points of interest to gather large caches of wood, scrap, and chemicals.
Frequently Asked Questions
Can you relocate workbenches without penalty in Voidtrain?
No. Dismantling a workbench returns approximately half of the crafting resources used to build it. You must spend materials to craft it again. Only the driving mechanic pieces can be freely picked up and rearranged.
How do you unlock furniture and train decorations?
Decorations are unlocked by finding Rofleemo creatures at depots, assigning them to perches on your train, and feeding them mushrooms gathered from loot chests. Each mushroom given prompts the Rofleemo to produce a random decor recipe.
What is the maximum number of train wagons you can build?
The official Steam achievement list includes an objective for constructing a total of 12 wagon platforms.
Where can you upgrade and expand train platforms?
Platform expansions and structural train lengthenings can only be purchased and applied at the terminals located inside outpost and depot stations, not while traveling across the open Void.
