I was watching Master Hellish’s recent co-op streams where his team was building massive “open-field” transport hubs using high-speed vacuum trains (Vactrains) fed by localized metro lines. It looked like an unusual, overkill layout on paper, but after looking into how the mod functions alongside the base game’s engine, it makes perfect logistical sense. If you are hitting late-game boredom and want to break the standard speed limits of MagLev, here is how to set up a high-speed Vactrain network without grinding your economy to a halt.
The Obstacle
There is an obtacle: : Vanilla MagLev vs. Rigid Vacuum Tubes. By default, standard MagLev trains cannot run inside vacuum tube lines. Most base vacuum sets are incredibly rigid; if you transition your network into the far future, your existing MagLev trains will trigger compatibility errors and refuse to enter the tubes.
- The Mod Solution: I use the Vactrain Set 1.1.FORK (Version 1.1.3) by WORD559. This specific community fork bridges the gap, allowing your vanilla MagLev wagons to actively couple with high-speed vacuum engines inside the tubes.
- The Catch: You must construct a native MagLev Depot first to build the trains inside your vacuum network, and you need to prepare your bank account for exorbitant track construction and vehicle maintenance costs.
The Bottleneck
There is also a bottleneck: There are Bridge Speed Limits. You can spend millions laying down perfectly straight vacuum tube lines, but the moment your 1,000+ km/h vactrain hits a standard OpenTTD bridge, it will violently slam the brakes. Vanilla bridges strictly cap futuristic vehicle speeds.
- The Remedy: You need to pair your vactrain set with custom bridge NewGRFs.
- The Sets to Use: Total Bridge Renewal Set (TBRS) or NuTracks. These replace vanilla graphics with modern designs that have zero speed limits for MagLev and Vacuum track types, allowing your trains to maintain full throttle cross-continent.
The Strategy
They say that for every problem there is a solution: The Open-Field “Hub-and-Spoke” Model Why did Master Hellish’s team build their giant Vactrain hubs out in open fields away from towns, and why feed them with slow local metros and freight trains? It all comes down to bypassing game restrictions:
- Bypassing Local Authority Rage: Bulldozing a massive, 14-tile long future station inside a city will tank your local authority rating to “Appalling,” banning you from expanding. Building in an open field gives you unlimited space with zero restrictions.
- Accommodating Insane Turning Radii: At triple-digit speeds, Vactrains cannot handle sharp 90-degree turns without losing all momentum. They require massive, sweeping diagonal curves that only open fields have room for.
- The Feeder Vacuum Effect: You use cheap commuter metros or local freight trains to act as a conveyor belt. They scoop up cargo from scattered cities and industries, bring them to the open-field hub, and use the “Transfer” command to dump them. Your massive Vactrain then bulk-loads that mountain of pooled cargo and fires it across the map for an astronomical, distance-multiplied payout.
I how you learned something from this. I know I did. Until now I have shied away for some of these fancy add on mods and newer vehicle types. Now that I have see Master Hellish use them a few time and that I have a better understanding of the obstacles that need overcoming I feel better equiped to tackle the problem and start using them in my game strategy.
More Details
Here are the two best ways to maximize your high-speed network using the Vactrain Set Fork:
1. Recommended Bridge Sets (No Speed Limits)
Standard OpenTTD bridges will cap your Vactrain speeds. To fix this, add one of these NewGRF sets to your game:
- Total Bridge Renewal Set (TBRS): This replaces vanilla bridges with modern designs that have no speed limits for MagLev and Vacuum tracks.
- NuTracks: A comprehensive track set that includes specialized, limitless bridges built specifically for futuristic rail types.
2. Vactrain Fork Configuration & Tips
To get the most out of your MagLev/Vacuum hybrid lines, keep these gameplay settings in mind:
- Check the Parameters: When adding the Vactrain Fork in your NewGRF menu, check the parameter settings. Some versions allow you to change the climate availability or adjust the base costs if the maintenance feels too punishing.
- Introduction Year: By default, these tracks and vehicles start appearing around the year 2021 to 2030. If you are playing an earlier scenario, you will need to use the cheat menu (
Ctrl + Alt + C) to enable “Allow electric rails” or change the current year to unlock them early.

The history of vacuum trains (Vactrains) in OpenTTD bridges real-world futuristic concepts with the evolving technical capabilities of the game’s modding engine. While it is not an everyday search topic for the general public, it remains a highly discussed, specialized niche within the OpenTTD community whenever players hit the game’s default end-year. [1]
Here is a look at the mod’s history and its community presence:
History of the Vactrain Mod
- The Inspiration (2010s): The concept of vactrains—like the Swissmetro or Elon Musk’s Hyperloop—gained massive real-world media attention in the 2010s. OpenTTD modders wanted to translate this ultra-futuristic tech into the game. [1, 2, 3, 4]
- The 2011 Original: Modder Brianum released the initial “Vacuum-Monorail set” around 2011. It was incredibly rudimentary because the base game engine back then struggled to support custom rail logic and extreme speeds. [1]
- The 2018 Breakthrough: Prominent modder Emperor Jake released the definitive Vactrain Set 1.0.1. This version entirely overhauled the graphics to look like transparent tubes, added full cargo support, and pushed vehicle limits to simulate frictionless travel. [1, 2]
- The Modern Forks: Over time, players realized the mod was too rigid. If you hit the year 2050, the tracks were great, but you couldn’t run your existing MagLev trains through them. This prompted community forks—like the Vactrain Set 1.1.FORK by WORD559 you are using—specifically to bridge the gap between vanilla MagLev and the modded tubes. [1, 2]
How Often Do People Look It Up?
- Niche Community Search Volatility: Because OpenTTD is a classic, long-standing simulator, searches for “Vactrain” on the BaNaNaS mod repository or the TT-Forums generally spike whenever a major Let’s Play series hits YouTube.
- The “Late-Game” Problem: Most players search for this mod when they experience “late-game boredom.” Once a player builds a massive empire by the year 2030 or 2040, vanilla MagLev trains hit a ceiling. Players search for vacuum sets to introduce an endgame financial challenge and unlock speeds exceeding 1,800 mph.
- Troubleshooting Content: The most common reason people search for it today is compatibility errors—exactly like the question you had regarding why standard MagLevs or bridge speed limits break the modded vacuum lines. [1, 2, 3, 4]
Are you currently designing an endgame map that spans into the far future, or are you just experimenting with how fast you can push the OpenTTD engine? I can give you tips on how to handle signaling at 1,000+ mph so your vactrains don’t constantly crash into each other.
