What the developers have to say:

Why Early Access?

“VR train simulation of this kind has never been done before, and as a three-people team we think immediate community feedback will help greatly to keep the game on the right track. It will also make development a whole lot more fun and engaging.

With that said, we've spent over a year making Derail Valley as feature complete as possible before launch to ensure it is a fun game worth purchasing. Already in its first version it will offer many hours of gameplay.”

Approximately how long will this game be in Early Access?

“At least several months, and possibly for years to come. The longer we can keep going, we will do so. Regardless of the Early Access status, our goal is to make Derail Valley the best VR train simulation game.”

How is the full version planned to differ from the Early Access version?

“Prior to Early Access we will reveal a roadmap detailing all the features and content we want to add during Early Access, which includes world expansion, new trains, and some other very significant features.

Derail Valley can be expanded in countless ways, and we will prioritize our updates based on available resources and community feedback.”

What is the current state of the Early Access version?

“At the time of Early Access release, Derail Valley will be fully playable, offering two locomotives (diesel-electric shunter and a heavy freight steam engine), a 256 km² world with a complex railway network occupied by NPC trains, procedural missions and a compelling challenge.”

Will the game be priced differently during and after Early Access?

“With every major update, the game price will increase. We will have more information on this closer to the Early Access release.”

How are you planning on involving the Community in your development process?

“We love community feedback and suggestions! There are many additions and improvements that we've planned for Derail Valley, and being a small team, each comment, forum discussion, gameplay video or stream will be very helpful for us in deciding what to do next.

Additionally, input from real life train experts is more than welcome.”

Funded and expanding the team!

We got some amazing news - we’re funded for the entire duration of Early Access!

In February we will expand our team to five members and work on Derail Valley for at least one full year during Early Access. That’s without taking into account actual revenue which should allow much more. This pretty much guarantees us delivering a full game in early 2019, with Early Access starting in a few months. Here’s what it means:
  • We can focus on development without dependence on initial success
  • We can reveal our full roadmap for the final game (coming in the next months)
  • We’ll have regular updates during Early Access (starting early 2018)
  • High chance of bringing the game to completion (early 2019)
  • We’re very motivated to do this
Some of you might remember that last summer we’ve spent a month preparing an application for funding. It was for the Serbian Innovation Fund, an organization focused on funding innovative technologies here in Serbia. Recently we were informed that we made it to the finals, and then invited to pitch in front of the jury of international investors. Out of 237 company applications from all kinds of industries (including medical, agricultural, machine, etc.), we were among the 25 to receive the funding. Here's the cool part:

We retain full freedom to do what we believe is the best for the game, without sketchy compromises. In fact, our vision and plan for the Early Access development is already on paper, and our only obligation to the Fund is to actually deliver what we set in it, on a quarterly basis. We will reveal this roadmap in the following months, and we think you’re going to love it.


As a team of a few people who started making Derail Valley with our own savings and an ambition to make a dream-game of every train sim fan, we’re super thankful to the Serbian Innovation Fund and their jurors who recognized our potential and agreed to fund us. There will surely be many obstacles and hiccups along the way, but we’re determined to make Derail Valley the best train simulation out there and possibly this way help VR market grow and become more affordable.

Finally, thank you all for the support and feedback you’ve sent us - without you we wouldn’t have had anything to show to the investors as proof that this is a game you want. Do spread the word about the game - tell everyone that it’s coming, and it’s going to rock!

We will be opening job positions soon in more detail, but in summary we are looking for developers already located in Serbia: two experienced gamedev programmers and one experienced gamedev 3D artist. If you live in Serbia, fit the criteria and would love to work with us on Derail Valley, send us an email with CV and portfolio to

In the next post we aim to reveal the upcoming steam locomotive (you can see some interior shots here already)! I’ll also sneak in a reminder that we’ve got a Discord. Feel free to drop by - we are active there daily.

Thanks for reading and see you all soon!

Sign up for closed beta!

Hey everyone,

Closed beta signups for Derail Valley have begun!

As announced in our previous post, we will be providing beta access to selected core community members on September 30, and slowly expand it to more testers over the following weeks and months.

Apply for the beta here:

Note that we don’t guarantee access to every tester who signed up. Amount of approved testers will be limited and we will prioritize those who have actively participated in discussions on forums or Discord, as well as those who have logged in significant amount of playtime with the demo.

Note: Steam lets us see playtime of demos only if you played them recently. If you haven't played Derail Valley demo in the past two weeks please start and close the game so it becomes visible on your Steam profile under “All Recently Played”.

We’ll start with a small group of selected testers and during beta include more testers with each update. Updates are aimed to be made on a weekly basis. If you’ve been given access, you will receive an email from us.

Why beta?

In case you missed it, give our previous post a read. Our goal with the beta rollout is primarily to provide something new to those of you who have been eagerly waiting for the now postponed release, but also to receive feedback, performance and bug reports regarding new features.

Tester community:

In the next days we’ll establish dedicated channels where beta testers will be able to provide feedback, discuss updates between each other and receive information about beta updates. We’ll include those in the beta access confirmation email.

Game status:

We are calling it closed beta as it gives beta access for the Early Access release. However the game itself is in pre-alpha state, and will only be in alpha when it is released in Early Access.

As expected the game is incomplete and heavily in progress. Initial “beta” release will showcase some additions, but expect a lot of missing features, content and polish (especially due to transition to the large world). From the initial beta release we will be updating the game regularly, adding missing features and content.

Until we get the game to a more satisfactory state, please note that we ask testers not to reveal any information about beta content publicly, including descriptions, reviews, screenshots or videos. You will be able to share this information with other testers however, and later publicly once we’re happy with the game’s state and have explicitly permitted sharing.

Beta duration:

We’re yet to determine how long the beta signups and beta access will last. This will probably be as long as it takes us to get the game to the intended level of completeness for Early Access release.

About This Game

Derail Valley is a train simulation made for VR. Pick assignments, drive trains and build your career in a vast railway network. Occasionally you might find yourself grabbing the controls in panic - the thought of running off the rails will run through your mind, and in all likeliness that's exactly what will happen. Don't worry though, the view from the cliff will be astonishing.

While still early in development by a three-people team, Derail Valley brings many advancements to both VR and train simulation games:
  • Unmatched immersion level

    Push levers and press buttons with your own hands. Feel being inside a moving train, even when it derails. Step outside into the nature and watch other trains pass by. Derail Valley is designed right from the start for VR in terms of optimizations, controls and UI.
  • Realistic AND intuitive

    Whether you're new to trains or an engineer veteran, you'll find that it's fairly simple to set the massive vehicle in motion. Keeping it on the tracks and completing assignments however will challenge you.
  • Dynamic, engaging gameplay

    Build a career as a train driver. Pick and complete procedural assignments, switch junctions, change locomotives, all in a seamless immersive experience. Make sure your train is safe and on the tracks! Earn money for that new locomotive you always wanted!
  • Vast railway network

    A single 256 km² world filled with meadows, fields, forests, lakes, hills and mountains. Seamlessly traverse it via mainline railway occupied by other NPC trains, or take a peek in various branches and train yards. We'll further expand it during Early Access!
  • Different train types

    At your disposal are a diesel-electric shunter and a heavy freight steam engine, two entirely different machines. They are fictive, but simulate behavior of their real counterparts. Electric and passenger trains will be added during Early Access.
  • Advanced railway simulation

    Get a feel for the railway and sense the bumps, joints and bends as wheels roll over them. Cherish the good condition of the mainline compared to the dark horrors of branch yards.
  • Derailment physics

    As a train driver, you'll find derailments to be your deepest fear. They are realistic, massive and dangerous, but also oddly spectacular and an amazing VR experience.

The world of rail transport is imperfect and in Derail Valley we want to let players experience that imperfection - be it through old rusty tracks, worn-out rolling stock set in a middle of nowhere, bunch of paperwork on your desk, or an empty wallet. At the same time it is a peaceful, coordinated and dynamic experience that gets increasingly rewarding with more skill.

Free Demo:

Derail Valley demo is a free small-scale version of the game. It offers a shunter locomotive and four challenging shunting missions in a 4km² natural environment surrounding a lake. It alone provides a few hours of gameplay. Give it a try!

Future plans:

We're currently working on the upcoming Early Access release with features described above, which will also be accompanied by a roadmap describing what's to come until final release - stay tuned! In the meantime be on a lookout for our news posts and updates and if you have any questions, comments and feedback please let us know on our Steam forum or Discord!
