Overfreight maps determine the geographic difficulty, elevation challenges, and construction costs for your rail network in OneSkyVed's Roblox logistics simulator. The game features three core maps: Flatlands, Twin Peaks, and Mountain Insanity. While every map contains the exact same set of industrial production facilities, their terrain layouts drastically change how you plan tunnels, bridges, and delivery routes.
Overview of Overfreight Maps
Each map in Overfreight comes with a distinct terrain profile, recommended player skill level, and designated livery color. Players can manage up to five save files across the available maps, with separate options for standard play and Realistic Mode.
| Map Name | Difficulty | Livery Color | Terrain Profile | Key Geographic Features |
|---|---|---|---|---|
| Flatlands | Easy | Green | Predominantly flat with 2 raised zones (up to 103m) | Central river, western urban cluster, starter bridge, and abandoned tracks |
| Twin Peaks | Normal / Medium | Beige | Two raised plateaus with central valleys | Frequent elevation changes, classic pre-alpha layout, tightly clustered industries |
| Mountain Insanity | Hard | Pink | Rugged mountain ranges and isolated islands | Water boundaries to the west, steep slopes, restricted water building |
Every map hosts identical supply chain points, including Deforestation Volunteers, sawmill facilities, sand pits, coal mines, iron smelters, copper facilities, and urban Freight Terminals. Because industry locations remain fixed for every player on a given map, learning each map's layout makes planning profitable loops significantly easier.
Flatlands (Easy Difficulty)
Flatlands is the standard entry point for beginners in Overfreight. The terrain consists of three large flat sections, one hill, and two elevated zones reaching up to 103 meters. A river splits the landscape through the center, while city infrastructure is clustered primarily along the western edge.
When loading into a standard Flatlands save, players start with pre-placed infrastructure that helps kickstart initial cash flow:
- A starter bridge crossing toward the Suspiciously Cheap Product Assembly Plant.
- An abandoned track section leading toward the central Freight Terminal, which can be upgraded or integrated into early delivery loops.
The flat topography minimizes construction costs because you rarely need to build long viaducts or drill expensive tunnels to connect basic timber and furniture production.
Key infrastructure locations on Flatlands:
- The World Connection tunnel is located directly adjacent to the iron mine and the sand extraction site.
- The Red Criminal Industry is positioned near the illegal copper mine and the copper processing plant.
Twin Peaks (Normal Difficulty)
Twin Peaks is the classic map of Overfreight, featuring two prominent raised regions separated by valleys. Because the terrain includes continuous elevation shifts, trains encounter steep slopes that can restrict speed if locomotives are underpowered or heavily loaded.
Despite the steeper grades, Twin Peaks offers a major economic advantage for early game progression: industries are situated in close physical proximity. Wood, plank, coal, and sand facilities sit closer together than on any other map. This tight clustering allows players to lay short, inexpensive track connections between processing plants without spending millions on extensive elevated bridges.
Key infrastructure locations on Twin Peaks:
- The Red Criminal Industry is positioned near the illegal copper mine and sits directly next to the coal mine.
- Valley floors provide natural corridors for main lines, though crossing between the two peaks requires careful slope management to prevent track placement errors.
Mountain Insanity (Hard Difficulty)
Mountain Insanity represents the highest logistical difficulty in Overfreight. The map is defined by rugged alpine peaks, dramatic height disparities, and isolated landmasses separated by deep water. The entire western boundary consists of open water, and building track directly over open water is blocked.
Track planning on Mountain Insanity requires heavy capital investments in tunnels and high-altitude bridge supports:
- Internal mountain sectors often allow tunnel excavation, but outer mountain rings frequently reject tunneling tools due to boundary limits.
- Steep natural inclines can cause loaded freight trains to stall or decelerate severely unless high-speed or electric locomotives are deployed.
- Track layouts must navigate around cliffs, meaning basic point-to-point connections require significantly higher track expenditures than on Flatlands.
Key infrastructure locations on Mountain Insanity:
- The World Connection tunnel is situated near the second Deforestation Volunteers site.
- The Red Criminal Industry is located near the iron mine.
Realistic Mode Map Variants
With the introduction of Realistic Mode, players can choose between six total map options when starting a new save file. This includes the three original maps under standard rules, and the three identical maps under Realistic Mode mechanics.
Entering a map in Realistic Mode requires unlocking the "A nice gift" badge on a normal career save (achieved by completing the Electric Locomotive research; sandbox saves do not qualify).
Key differences across all maps when playing Realistic Mode include:
- A starting budget of $50,000 cash paired with a 75% income bonus on all cargo deliveries.
- Complete absence of an introductory tutorial.
- Decoupled operations: locomotives and freight cars are purchased separately rather than operating as locked units.
- Mandatory Sorting Yards: trains do not magically flip at end stations. Players must build designated yards (up to 500m by 200m) to manage shunting, car decoupling, and reversal methods (Terminus, Turnaround, or Speed-Limited Reversing).
Frequently Asked Questions
Can you switch an existing save file to a different map?
No. Map selection is permanently locked when creating a save file. If you wish to build on Twin Peaks or Mountain Insanity after starting on Flatlands, you must open a new save slot from the main menu.
Do harder maps have more industrial facilities?
No. The total number and types of industrial processing plants are identical across Flatlands, Twin Peaks, and Mountain Insanity. The difficulty differences stem entirely from terrain barriers, water hazards, elevation grades, and the track costs required to bridge them.
What is the purpose of Passenger Stations across the maps?
Passenger Stations are optional transport hubs scattered across all maps. Running passenger trains between stations or delivering passengers directly to industrial production facilities grants a 2x production speed boost, allowing connected factories to manufacture materials twice as fast.
Where do World Connection trains travel on each map?
Regardless of which map you play, World Connection NPC trains travel straight toward your local Freight Terminal. Track lines originating from the World Connection tunnel should only be routed directly into a Freight Terminal platform to avoid pathfinding jams.
