Wagons and Upgrades

Your train is the single most important thing in Unrailed!. Every wagon you add and every upgrade you purchase determines whether you survive the next biome or derail three levels in. This guide covers every wagon type, the animal ecology system, the bolt economy, engine progression, and the upgrade strategies that separate first-biome crashers from endgame runners.

info

Wagon availability and upgrade costs can shift between game versions. This guide reflects the full release version of Unrailed! (post-1.0). If you are playing an older build, some details may differ.

Default Wagons

Every train starts with these three wagons. They cannot be removed or replaced. Upgrading them is always your first priority.

Crafter Wagon

The Crafter converts raw materials into track pieces. Drop wood and stone onto it, and it outputs finished track.

Level	Effect
Level 1 (default)	Base crafting speed. Converts 1 wood + 1 stone into 1 track piece.
Level 2	Faster crafting speed. Reduces the time between each track piece output.
Level 3	Maximum standard crafting speed. Produces tracks nearly as fast as you can deliver resources.

Priority: Upgrade the Crafter to Level 2 as early as possible. The default crafting speed is the bottleneck on most early runs. A Level 2 Crafter lets your team work ahead of the train instead of constantly catching up.

Storage Wagon

The Storage wagon holds overflow resources and crafted tracks. When the Crafter output slot is full, finished tracks go here. You can also dump raw resources into Storage to buffer supply.

Level	Effect
Level 1 (default)	Holds a small amount of resources and tracks.
Level 2	Increased capacity. Holds significantly more items.
Level 3	Maximum standard capacity. Enough buffer to survive resource droughts.

Priority: Upgrade to Level 2 after the Crafter. A bigger Storage wagon lets you stockpile tracks during easy sections and spend them during hard ones.

Tank Wagon

The Tank wagon stores water for engine cooling. Players can fill the Tank by carrying bucket loads to it. Tank upgrades extend the auto-cooling range when positioned near the engine.

Level	Effect
Level 1 (default)	Basic water storage. Manual bucket-to-engine cooling required.
Level 2	Increased capacity. Slightly extends auto-cool range to the engine.
Level 3	Maximum standard capacity and auto-cool range. Significantly reduces manual cooling duty.

Priority: Upgrade to Level 2 once Crafter and Storage are handled. A Level 3 Tank is a luxury that frees up a player from bucket duty, but it is not essential until the Desert or later biomes.

Purchasable Wagons

At each station, you can spend bolts to add new wagons to your train. Your train has a wagon capacity limit determined by your current engine. Adding a wagon when your train is full replaces the wagon you drop the new one on top of.

Dynamite Wagon

Passively produces dynamite sticks over time. Dynamite clears a large area of trees, rocks, and terrain obstacles when thrown.

Level	Effect
Level 1	Produces dynamite slowly. Small blast radius.
Level 2	Faster production. Medium blast radius.
Level 3	Rapid production. Large blast radius. Clears massive swaths of terrain.

tip

The Dynamite wagon is widely considered the single best purchasable wagon in the game. A Level 3 Dynamite wagon clears entire sections of terrain in seconds, reducing the need for manual chopping and mining. Prioritize it in any serious Endless run. Note: dynamite production is passive — the wagon does not require loading with any resource.

Ghost Wagon

Allows players and entities to pass through the wagon itself. Normally, your growing train becomes a physical barrier that forces players to walk around it. The Ghost wagon eliminates this problem.

Level	Effect
Level 1	Players can walk through the Ghost wagon.
Level 2	Ghost effect extends to wagons immediately adjacent to the Ghost wagon.
Level 3	Ghost effect extends further, covering most of the train.
Level 5 (via Supercharger)	Ethereal effect covers nine total wagons (the wagon itself plus four adjacent wagons on each side).

Why it matters: As your train gets longer with more wagons, walking around it to deliver resources wastes critical seconds. A Ghost wagon in the middle of your train lets players phase through it freely. This becomes essential in later biomes where every second counts. The Ghost effect also applies to animals attached to the Milk Wagon within its range, preventing them from being crushed by the train or detaching in narrow corridors.

Compass Wagon

Points toward the station, helping you plan your track path.

Level	Effect
Level 1	Arrow indicator points toward the station.
Level 2	Reveals the best route and provides a mini-map overlay. Cannot be upgraded further via standard upgrades.

When to buy: The Compass is useful in biomes with obstructed vision (Snow, Lava) or when the terrain forces long detours. It is not essential in the Plains or Desert where visibility is good.

Light Wagon

Provides illumination in dark biomes and melts snow in the Snow biome. Requires wood to fuel it.

Level	Effect
Level 1	Illuminates a radius around the wagon. Melts nearby snow. Requires wood fuel.
Level 2	Larger illumination radius. Greater snow-melt range.
Level 10 (via Supercharger + Time mode)	Maximum melt radius and fuel capacity. Scales linearly with each Supercharger boost.

When to buy: Essential in the Snow biome where darkness and frozen terrain make navigation dangerous. The Light Wagon's melt radius can be scaled well beyond Level 2 using consecutive Supercharger wagons, making it a viable endgame utility in high-score runs.

Supercharger Wagon

Boosts the effective level of adjacent wagons by one. This is the most strategically powerful wagon in the game and the cornerstone of all endgame builds.

Level	Effect
Level 1	Boosts wagons directly adjacent by +1 level.
Level 2	Extended range. Boosts wagons within two slots by +1 level.
Level 3	Maximum range. A fully upgraded Supercharger boosts up to six adjacent wagons simultaneously.

warning

The Supercharger pushes adjacent wagons beyond their normal Level 3 cap. A Level 3 Crafter next to a Supercharger effectively operates at Level 4+, which does not exist as a normal upgrade. Multiple Superchargers stack their effects — placing two Superchargers adjacent to the same wagon pushes it even further. This is how experienced players achieve the crafting speeds, Light melt radiuses (up to Level 10), and Buckinator charge durations (up to Level 9) needed for extreme-distance leaderboard runs. Position Superchargers carefully to maximize the number of critical wagons they boost.

Bucket Wagon (Buckinator)

When a standard water bucket is docked into the Buckinator, it becomes "charged." The charged bucket projects an area-of-effect (AoE) ring that empowers any player standing inside its radius.

Level	Effect
Level 1	Charged bucket provides minor AoE buff. Increases tool mining speed by 50% and doubles resource-carrying efficiency.
Level 2	Stronger AoE buffs. Extended charge duration.
Level 3	Maximum standard buff strength and duration.
Level 9 (via Supercharger)	Charge duration extends to 30 seconds per activation.

The stacking mechanic: Buckinator buffs stack multiplicatively with Milk Wagon animal buffs. A player wielding a charged bucket while under the effects of Camel milk sees their carrying capacity jump to 24 resources per trip. A well-coordinated team designates one player as a dedicated "buffer," carrying the charged bucket near primary harvesters to maintain uptime on these extreme efficiency multipliers. The charged bucket can also supercharge placed dynamite and instantly melt large areas of snow.

tip

The Buckinator is not just an upgrade to the standard bucket. It is a team-wide force multiplier. In the mid-to-late game, a Level 3 Buckinator positioned near your harvesters can double your effective resource throughput, especially when combined with Milk Wagon buffs.

Milk Wagon

The Milk Wagon is a game-changing utility wagon that generates consumable buffs from biome-specific animals. Lure an animal near the Milk Wagon and it physically attaches. Each animal type provides a unique 17-second buff when milked.

Animal	Biome	Buff
Cow	Plains	Three-fold tool efficiency. Destroys trees and permanent rocks in a single strike.
Camel	Desert	Quadruples carrying capacity to 12 items per trip.
Walrus	Snow	Immunity to the severe movement-speed penalty caused by deep snow. Normal traversal during blizzards.
Blowfish	Underwater	Prevents oxygen meter depletion. Grants infinite air supply.
Magma Blob	Lava	Grants a ghostly ethereal effect. Player passes through other players, obstacles, and the train without collision.

Stacking: Animal buffs stack multiplicatively. Milking different animals simultaneously combines their effects into a single consumption action. A player under Cow + Camel milk instantly mines dense clusters and transports 12 blocks per trip.

warning

Keeping animals attached to the Milk Wagon is one of the game's biggest challenges. In narrow corridors, the physics engine triggers entity cramming, causing animals to forcibly detach, wander off, or get crushed by the advancing train. The Ghost Wagon is mandatory alongside the Milk Wagon — when the Ghost Wagon's ethereal radius covers the Milk Wagon, all attached animals also become ethereal, preventing accidental detachment and death.

Additional Wagons

Wagon	Function	Max Standard Level
Shield Wagon	Protects the train from environmental hazards (fire, ice, projectiles, asteroid strikes).	Level 3
Horn Wagon	Emits a horn blast that clears or stuns environmental threats in a radius.	Level 3
Cannon Wagon	Fires projectiles at the opposing team. Versus mode exclusive.	Level 1
Transformer Wagon	Converts one resource type into another. Niche utility.	Level 3
Slot Machine Wagon	Randomized output when loaded with resources. High-risk, high-reward utility.	Level 3

info

The Transformer and Slot Machine wagons are creative options that provide situational value, but the Supercharger meta renders them mathematically obsolete in extreme late-game runs. Use them for variety on Easy and Medium difficulties, but swap them for Superchargers when pushing for distance records.

Engine Progression

Your engine determines two critical things: which biome you can access next, and how many wagons your train can hold. The Underwater biome is an optional detour accessed via mineshafts, not a mandatory engine-gated stage.

Engine	Biome Unlocked	Wagon Capacity
Starter Engine	Plains	3-4 wagons
Engine 2	Desert	5 wagons
Engine 3	Snow	6 wagons
Engine 4	Lava (Hell)	7 wagons
Engine 5	Space	8 wagons
Engine 6	Mars	9 wagons
Final Engine	Final Biome	Maximum capacity

info

The Final Engine requires collecting orange special bolts from the third section of every biome. These special bolts unlock the alternative fireworks ending and new playable characters. A standard credits ending is reachable without them, but missing a special bolt locks you out of the true conclusion. Collect every special bolt you encounter.

Bridge Materials

The resources required for bridge construction change as you progress. This shift is one of the most common causes of late-game derailments.

Biomes	Bridge Material	Why
Plains, Desert, Snow	Wood	Water crossings use wooden pontoon bridges.
Lava (Hell), Space	Stone	Wood incinerates on contact with lava. Stone bridges are mandatory.

warning

A team that arrives in the Lava biome with a Storage wagon full of wood and depleted stone reserves will derail at the first lava flow. Begin stockpiling stone in the Snow biome to prepare for the material shift.

The Bolt Economy

Bolts are scarce and spawn deterministically. Understanding how to earn and spend them efficiently is the difference between a stacked train and a bare-bones deathtrap.

Earning Bolts

Source	Details
Map spawns	Found in hard-to-reach locations across levels. May require detour bridges to collect. Deterministic, not random.
Station missions	Awarded for completing specific objectives (e.g., "prevent any player from being eliminated," "use a minimum amount of dynamite").
Special bolts	One per biome, found in the third section. Orange-colored. Worth 2 regular bolts each. Required for the Final Engine and fireworks ending.

Spending Bolts

Priority	Upgrade	Reasoning
1st	Crafter to Level 2	Eliminates the crafting bottleneck.
2nd	Storage to Level 2	Buffers resources for hard sections.
3rd	Dynamite Wagon (new)	Clears terrain faster than manual tools.
4th	Dynamite to Level 2-3	Exponentially increases clearing power.
5th	Ghost Wagon (new)	Removes train-as-barrier problem. Essential for Milk Wagon animals.
6th	Tank to Level 2	Reduces cooling pressure.
7th	Supercharger (new)	Pushes critical wagons past normal limits.
8th	Milk Wagon (new)	Unlocks animal buffs for massive efficiency gains.
9th+	Situational	Light (Snow), Compass (blind biomes), Buckinator (buff stacking).

tip

Resist the urge to buy every new wagon early. A few well-upgraded wagons outperform a train full of Level 1 wagons. Focus depth over breadth in the first three biomes.

Wagon Positioning

Where you place wagons on the train matters. Some wagons have range-based effects (Supercharger, Ghost, Light), so their position determines which other wagons benefit.

General rules:

• Place the Supercharger in the center of your train to maximize the number of wagons it boosts (up to six adjacent wagons at Level 3).
• Place the Ghost wagon so its ethereal radius covers the Milk Wagon and its attached animals.
• Keep the Tank wagon adjacent to the engine for maximum auto-cool effectiveness.
• Place the Dynamite wagon where players can easily reach it to grab dynamite sticks.
• Position the Milk Wagon within the Ghost Wagon's range to prevent animal detachment.

warning

Rearranging wagons costs time at the station and sometimes a bolt. Plan your wagon layout before you buy, not after. A bad layout wastes the positional bonuses that make wagons powerful.
