Overfreight gems, also labeled as Diamonds in the game interface, serve as the premium currency in OneSkyVed's Roblox train simulation game, Overfreight! Players use gems to unlock train mesh customization, color palettes, and diamond-exclusive career research tiers like Longer Trains 2 and Longer Trains 3. While gems can be purchased directly with Robux, players can also earn them for free through in-game daily tasks and regional rewarded ads.
| Acquisition Method | Gem Payout | Details and Limitations |
|---|---|---|
| Daily Tasks | 10 gems per task | Requires fulfilling delivery targets (such as hauling sand or city goods); has an active cooldown before the next task |
| Rewarded Ads | 5 gems per ad | Availability depends on your region; cooldowns range between 15 to 19 hours after watching |
| Robux Shop | 50 diamonds for 50 Robux | Available through the top-right Shop or Gems/Diamonds menu button |
| Player Gifting | Varies | Players can gift developer products directly to another user by entering their username |
How to Get Free Gems in Overfreight
Players can accumulate gems without spending Robux by using two recurring mechanics introduced in game updates.
Completing Daily Tasks
Daily tasks award 10 gems upon completion and can be tracked inside the shop menu. These objectives typically demand large-scale logistical operations, such as delivering 8,000 tons of sand to processing industries or moving 8,000 tons of city goods between freight terminals.
Tasks can progress automatically while running routes or going AFK, provided the task is actively running and your trains are maintaining active delivery lines. Once a daily quest is finished and the 10 gems are claimed, a cooldown timer begins before a new task becomes available.
Watching Rewarded Ads
Clicking the gems counter bar at the top right of the screen opens the currency interface, which features a "Watch Ad" option. Each completed ad grants 5 gems.
Ad availability relies strictly on Roblox's regional ad support and individual account location. If ads are limited or less frequent in your region, cooldown timers between viewings can span 15 to 19 hours.
Purchasing and Gifting Diamonds with Robux
For players looking to acquire currency immediately, diamonds can be purchased from the in-game shop.
- Direct Purchase: The base shop rate lists 50 diamonds for 50 Robux. Access this menu by clicking either the "Shop" button or the "Gems/Diamonds" counter located in the top-right corner of the GUI.
- Player Gifting: The shop menu supports gifting. Entering another player's Roblox username lets you purchase and deliver diamond or cash developer products directly to their account on the server.
How to Spend Gems and Diamonds
Gems are scarce, making targeted spending necessary to avoid wasting currency on reversible builds.
Train Configuration and Mesh Unlocks
Customizing rolling stock requires unlocking individual train configurations using gems:
- Standard Train Customization: Unlocking the customization menu on a locomotive costs 5 gems under default settings. An update reduced this cost to 3 gems when playing in realistic mode.
- Mesh and Livery Features: Paying the unlock fee allows you to assign custom Roblox decal asset IDs for liveries, paste custom mesh IDs and texture IDs for engines or passenger cars, and set custom RGB values.
- No Refund Warning: Locomotives that have already had a customization pass unlocked cannot be deleted for a gem refund. Any gems spent on a specific train configuration are permanently lost if that train is discarded.
Research Progression
Most research in the progression tree uses standard game cash and cargo delivery completions, but diamonds are required for select high-tier nodes:
- Exclusive Research: Upgrades such as Longer Trains 2 and Longer Trains 3 specifically mandate diamonds to complete and cannot be finished with standard cash alone.
- Instant Research: Diamonds can also be spent to skip research delivery waiting timers and finish projects instantly, though saving gems exclusively for mandatory diamond tiers is standard practice.
- Badge Completion: The in-game badge "Overfreight!" requires finishing all career research projects, but officially excludes the nodes that require diamonds.
Frequently Asked Questions
Are diamonds and gems the same currency in Overfreight?
Yes. The terms "gems" and "diamonds" refer to the same premium currency in Overfreight. The top-right GUI displays the balance under the Gems/Diamonds counter.
Can I get a gem refund if I delete a customized train?
No. Once you spend gems to unlock the configuration menu for a locomotive or railcar, you cannot recover or transfer those gems if the locomotive is removed.
Do I need diamonds to earn the Overfreight badge?
No. The official badge description for "Overfreight!" specifies that you only need to finish the standard research tree, excluding all research that requires diamonds.
