Overfreight Locomotives: Complete Stats, Tiers, and Rail Guide

Overfreight locomotives serve as the primary power source for hauling freight cars, passenger coaches, and industrial materials across your railway network in the Roblox simulation game created by OneSkyVed. Players begin career saves with a single diesel engine and gradually unlock faster diesel and electric units through technology research. Choosing the right locomotive tier determines your train acceleration, top track speed, and route electrification requirements.

Locomotive Tiers and Technical Statistics

The following table details all confirmed locomotives currently documented in the game files and community records, including top speeds, dimensions, and purchase prices.

Standard Locomotive Roster Breakdown

Overfreight organizes its engines into four progressive tiers based on European prototypes, primarily from the Czech railway operator České dráhy (ČD).

Tier 1: Diesel Engine (ČD Class 740/742 "Tomcat")

The starter locomotive available to every player upon creating a new save. The ČD Class 740/742 operates as a reliable, low-cost diesel shunter. With a top speed of 80 km/h, it is well-suited for short feeder lines such as moving raw logs between logging camps and shaping facilities. It can traverse any track type without requiring electrification.

Tier 2: Faster Diesel Locomotive (ČD Class 750/754 "Goggles")

Unlocking the Faster Diesel Locomotive research introduces the ČD Class 750/754. This engine delivers twice the pulling power of the starter diesel and increases maximum travel speed to 110 km/h. It handles heavier intermediate cargo consists, such as coal and sand, across longer routes before you invest in full network electrification.

Tier 3: Electric Locomotive (ČD Class 362 "Fast Eso")

The first electric option unlocked in the tech tree, reaching a top speed of 140 km/h. Unlike diesel engines, electric locomotives require specialized electrified tracks across their entire operational route. If an electric engine encounters a non-electrified rail segment, it cannot travel on that track. Players frequently deploy this locomotive on high-volume routes transporting finished steel beams or electronics to freight terminals.

Tier 3 Alternative: Rusty Electric Locomotive

The Rusty Electric Locomotive is a specialized collectible variant awarded via the "A nice gift" badge. Players receive four of these units upon completing electric locomotive research in a standard career save. The engine features a rusted texture and has a lower top speed (documented at 91 km/h on the wiki and 80 km/h in player speed trials) compared to standard Class 362 units. These engines cannot receive custom liveries or front/rear locomotive coupling modifications, and they cannot be repurchased if sold.

Tier 4: Faster Electric Locomotive (ES 64 U "Taurus")

The top-tier locomotive in Overfreight, based on the EuroSprinter ES 64 U platform. It features a base top speed of 230 km/h, which can be upgraded to 300 km/h through dedicated research. With double the power output of the Tier 3 electric engine, the Taurus is designed for high-speed express routes and long freight consists consisting of multiple platforms.

Core Locomotive Operations and Upgrades

Managing locomotives effectively requires understanding multiple mechanical systems introduced across the career and realistic game modes.

1. Multi-Locomotive Consists: Completing the Connected Locomotives research allows you to couple up to 3 locomotives together in a single train consist. Multi-locomotive setups provide increased horsepower and acceleration, allowing trains to maintain top speed when climbing mountain slopes or hauling heavy cargo.
2. Track Electrification Rules: Diesel locomotives run on all standard and electrified track variations. Electric locomotives stop or display path errors if any segment of their route lacks electrified rails.
3. Cloning and Reselling: Players can duplicate an existing locomotive and its attached cargo cars by pressing the Clone button in the train interface, which also duplicates the assigned route. Selling unwanted locomotives returns 35% of the original purchase price.
4. Engine Replacement: When upgrading from diesel to electric units, players can use the Replace button on an existing locomotive in the depot or yard to swap models without deleting and rebuilding the attached railcars.

Locomotive Handling in Realistic Mode

In Overfreight's Realistic Mode, locomotives and rolling stock are purchased separately rather than bundled as static units. This changes operational logic significantly:

• Yard Depots: Locomotives require an assigned sorting yard to serve as their depot. When a locomotive finishes a delivery or has no active assignment, it returns to its depot track. If no yard is available, the engine stops and displays the message "No yard found, build one."
• Route Ownership: In Realistic Mode, routing schedules and stops are assigned directly to the lead freight car (the main wagon) rather than the locomotive. The main wagon calls an available locomotive from the yard to fulfill the transport order.
• Locomotive Switching: Because electric locomotives cannot enter certain factory loading platforms, networks frequently use diesel shunters inside industrial branch yards. The diesel unit pulls cargo cars from the factory to the yard, uncouples, and an electric locomotive takes over for the long-distance mainline run. Enabling the "Use only assigned locomotives" setting prevents distant engines from wandering into local yards.
• Platform Reversal Maneuvers: Locomotives in Realistic Mode cannot instantly spin 180 degrees. Stations and factories configure reversal through three settings: Turnaround (locomotive uncouples and uses a bypass loop to attach to the opposite end), Terminus (a second locomotive couples to the rear to pull the train back out), or None/Push-Pull (the original locomotive pushes the consist in reverse under a reduced speed limit).

Train Customization and Liveries

In June 2026, Overfreight introduced an extensive custom train system. Players can configure train appearances by spending 5 Gems per train unit.

The configuration window permits applying custom community-made 3D meshes, textures, wheel models, and liveries. Complete configurations can be exported or imported using string codes, enabling players to share detailed train builds without manually adjusting mesh offsets. Popular community meshes circulating on player Discord servers include international locomotives such as the DB Class 101, Siemens ES64F (DB Class 152), Japanese Shinkansen series, and Indonesian KAI Commuter sets.

Frequently Asked Questions

Can electric locomotives run on standard rails in Overfreight?

No. Electric locomotives require electrified rails across every segment of their path. Diesel locomotives, however, can run freely on both standard and electrified tracks.

How do you get the Rusty Electric Locomotive?

You must unlock the "A nice gift" badge by researching electric locomotives in a standard career mode save. Sandbox mode saves do not qualify. Upon unlocking the badge, four rusty locomotives are delivered to your inventory.

Can you recover a sold Rusty Locomotive?

No. Once sold, the rusty locomotives cannot be repurchased or reclaimed through the store interface.

How many locomotives can be connected together in one train?

You can connect up to 3 locomotives in a single train consist after completing the Connected Locomotives research.

Why does a locomotive say "No yard found, build one" in Realistic Mode?

Locomotives in Realistic Mode need a designated yard to act as their resting depot when idle. If your track layout lacks an accessible sorting yard, unassigned locomotives will stop operating.
