Hi everyone! We've just released build 98, our latest update bringing you a new vehicle, new features, numerous improvements and bug fixes!


The tiny, quirky new battery-electric shunter takes the spotlight! There's two practical functions to it: it's the first vehicle to utilize the all new electric powertrain simulation, and, once unlocked, it can be requested anywhere with comms radio for a small fee!

Microshunter isn't powerful enough to replace a regular locomotive, but it can still pull some load. That, combined with its size and ability to be requested, give it a unique advantage in many situations. Mind how you treat it though, as you'll need to service it, and even charge its battery occasionally.


With this update we've also revamped (or rather finished) the diesel-electric powertrain simulation, now vastly more accurate when it comes to governors, generators, currents, voltages, circuitry, transitions, as well as failures from the all new traction motor overspeeding. DE locomotives have received a complete overhaul in terms of behavior and characteristics, with the highlights being:

DE2 – Increased load rating, improved cooling, heavier engine feel, rebalanced wear and tear
DE6 – Completely new sounds, more accurate notch distribution, rebalanced wear and tear
DE6 Slug - Now can be utilized from both ends and behaves differently


If you're curious what all those changes mean to the vehicles' performance, their various characteristics and even spawn locations are now listed in the new Vehicle Catalog handbook. The listing also features a series of scores designed to make easy practical comparisons. Generally, the catalog is intended to help players, whether new or experienced, decide what vehicle is best suited for a role they have in mind, with concise info.



Some work trains, such as Microshunter and Slug, are now able to receive damage. The only way to repair them is manually and, being player-owned, they're not covered by insurance. Handcar and caboose are intentionally kept invincible, however, so you don't need to worry about those.

A neat new feature on the career manager allows you to see health status of the work trains you own. The machine also shows coordinates for all vehicles in the world. Additionally, handcar is now a free vehicle, available to request at all times, which is especially helpful when needing to move around in Realistic difficulty.


You can now seamlessly adjust your height both in nonVR and VR. In nonVR you can do this with X+Mousewheel (adjusting your sitting position), and in VR by holding Triggers on both hands and lifting yourself up or down. Another novelty is the ability to save your favorite "cab" and "follow" camera positions.

We've put a lot of work into numerous CPU and GPU optimizations for this build. While the improvement may not be drastic for everyone, we've seen FPS rise up to 30% in certain conditions and hardware. Optimizations apply to both PC and VR players, and there's some more coming soon.


We've completely reworked the Vive controls, also fixing the weird calibration angle introduced in B97. The new controls no longer block you from walking while holding an item in the left hand and are generally more consistent with all the other controller types. The exact mapping is listed in the changelog below.


Vast improvements have been made to the career tutorial, locomotive tutorials and the manual. Whether you're a new player or a veteran, we strongly recommend you to complete the career tutorial again (in a temporary new session, if needed) – as it teaches of a lot of features and best practices that have been recently added to the game.


Apart from all this, numerous other improvements and bug fixes were made in this build. Manuals and various texts have also been updated too – and we'd like to say a big thank you to our dear beta testing and translation friends for being tremendously helpful with everything they do!

Hey everyone! We've just released a massive update, bringing numerous new features and bug fixes to Derail Valley.


To start off, we've added livestock, which can be found at the Farm industry. The animals are lively, moving around, making noises, and just generally contributing to the countryside atmosphere. Some of the smaller critters may even be seen crossing the tracks, but not to worry – they are immune to trains.

Along with the animals, we've added new types of cars and cargo to the game. The stock car type, pictured above, is now used to transport animals, which are visible inside and can even be heard reacting to physics forces and their health level. Another new vehicle is the short variant of the tank car, pictured below, used for milk transport.

Boxcars have been repurposed, now carrying new cargo types such as eggs, fruits and vegetables, but also wool and cotton, which now go to the Goods Factory. Hoppers too have been given a new cargo type – the sunflower seeds.

The cats' world domination has reached Derail Valley too, so naturally, you can now find strays in every city in the game. Unfortunately, you can't pick them up and carry around, although admittedly that would be very cool.

The systems developed to include these animals are the first step towards the implementation of passengers, pedestrians and wildlife to the game in the future.


There's now a new graphics setting called Terrain Lighting. If set to High it will notably improve the terrain shadowing with better accuracy and ambient occlusion, and it's not even significantly taxing on performance. If you still need the lighting to be the same as before, however, put the setting to Low.


We've added the equivalent of nonVR's mouse mode to VR. This is an accessibility feature, allowing players to aim at train controls with their hand and operate them remotely, without needing to physically reach for them. It's a substantial new way to play the game.

There is also a new difficulty setting called VR Remote Driving, which needs to be enabled for this feature to work. By default it is enabled in Comfort and Standard presets, but not in Realistic or existing custom ones.

In the future we plan to bring external camera and remote sign reading to VR too, along with the Driving UI, but that's not ready for this build yet. However, as a temporary measure, VR players do have access to the Weather Editor already, accessible via a button at the top-right corner of the inventory window.


The update also includes support for the new Quest 3 headset, vastly improved tutorial experience, as well as major bug fixes, such as disappearing money fix, DH4 tunnel item collision fix, objects in peripheral vision no longer disappearing on VR headsets with high FOV, and many, many more, as listed in the changelog below.

For players who have lost their in-game money due to a bug – please send us your save so we can fix it, allowing you to continue your session. You can do this either by emailing us to http://mailto:support@altfuture.gg or DM-ing @Manja on our Discord[discord.com]. The message should include:

- Your save file attached. (select your save in-game, then click the folder icon to get to it)
- Amount of money you wish to have returned. (add up for the cost of lost items too)


Since build 96 we were also able to focus on things other than strictly Derail Valley development, many of which were long due. Some of those involved:

- Creating a new kind of project management software, which drastically optimized our workflow.
- Updating a lot of our code and management infrastructure.
- Thoroughly planning out activities for the next year (more on that below).
- Working on the Soundtrack remaster (roughly 75% done, currently).
- Many other business activities that weren't in the spotlight.
- Taking time to rest and recover.

We'd like to thank you all for your continual support and making it possible for us to take actions with Derail Valley with the long-term approach!


With today's update we've entered the new era of Derail Valley development, the so called FP4, as per our roadmap[www.derailvalley.com]. Rather than go for a single major update in the future, we have decided to introduce new industries, cargo types and cars in small batches, over the next year or so. There are currently 6 phases planned for this and today's farm update marks completion of the first!

The upcoming period is going to get quite exciting in terms of new content getting added, however note that the focus will be on the new industries, cars and cargo, but not yet on railway network updates or the industrial ecosystem gameplay. Those will come at the end of FP4, and will be announced much later.

Many more things are being in development already. Stay tuned!

Those were the most important bits, but there are many more fixes and improvements in this build. Please see the full changelog below. Next, we will also work on improving the translations of the newly added/modified text in the game along with our translation team.

Hi everyone! We've just released the new update, featuring the new DE6 Slug and many other improvements to the game!



In real life when a locomotive reaches its end of life, some of its components can still be reused. Slugs are an example of that. They are modified diesel-electric locomotives, in this case a DE6, in such a way that they no longer have a diesel engine or a cab. What they do still have are the traction motors, and a body filled with concrete to make them heavy.

In Derail Valley the DE6 Slug is a "work train". What this means is that in career mode there's only one on the map, in a locked garage somewhere. The key for the garage can be purchased in the Harbor shop. Once unlocked, the vehicle can be moved around freely, and summoned using the comms radio, for a fee. In sandbox mode it's always available.


On its own the Slug is practically useless. When coupled to a diesel-electric locomotive via MU cable, however, it starts to make sense. Instead of feeding only its own traction motors, the locomotive now powers both its own and the Slug's motors. This drastically reduces the amperage per motor, allowing applying a lot more throttle without risk of overheating or slipping.

In other words, the Slug can help drastically increase the pulling capacity of a DE locomotive by utilizing its generator better at low speeds. However, this doesn't come without cost – apart from adding extra weight, the Slug's traction motors also provide significant additional EMF, making reaching higher speeds much more difficult.


Texture streaming – This update should bring a significant improvement to VRAM (and on some systems RAM) usage, as the game no longer holds all textures in memory the whole time but dynamically loads and unloads them as needed, instead.

Ray tracing – We've arranged it with Nvidia to support Derail Valley in their Freestyle feature, so if you have GeForce Experience installed and run the latest drivers you can enable filters for Derail Valley. The one we find most notable is SSRTGI, which does screen-space ray tracing (pictured below). Press Alt+F3 in-game to set it up.

QoL and bug fixes – We've made various small improvements, such as the ability to aim at items while zooming in mouse mode, or that unzooming in mouse mode now brings the camera back to its original position. Touch-based interaction with buttons in VR is now back too and this time works as intended (please do try it as it works great, and if you still don't like it there's an option to use Trigger instead). There are numerous other small improvements and bug fixes made, listed in the changelog below.

What's cooking? – We have many more things currently in development. Some of those are almost done and just need more testing to be included in the next build, whereas others are rather notable and are yet to be announced in the coming months!

• Added texture streaming
  • Instead of holding all textures in VRAM, the game now loads them dynamically
  • This drastically reduces required VRAM capacity
    
  • This also indirectly helps reduce RAM usage on PCs with limited VRAM
    
  • This should help prevent crashes and stuttering induced by RAM/VRAM shortage
    
  • Added options for this in Settings/Advanced
• Further reduced RAM usage (apart from texture streaming)

Hi everyone!

The new update is out, introducing a brand new steam locomotive to Derail Valley, as well as many bug fixes and improvements!


Due to its small size, the new locomotive has very different characteristics from S282, making it quite a unique new experience. In terms of hauling capacity it sits somewhere between DE2 and DM3, and can sometimes be found in small industries, such as forests. The new locomotive can be accessed in sandbox mode without unlocking too.

Besides the new locomotive, there are many other notable improvements made in this update, such as updates to coal firing and economy, many new water towers, VRAM optimizations and more. Check out the changelog below for more information.

• VRAM optimization
  • Reduced VRAM footprint of dynamically generated textures
    
  • Reduced VRAM footprint of some large assets
    
  • We’re working on texture streaming, to drastically reduce VRAM usage
    • It’s currently in the testing phase. To enable it use console command:
      
    • Graphics.StreamingMipmaps.Active 1
      
    • This is still in development and may not be flawless
• Fixed career progress corruption bug
  • Hardcore sessions were able to pull in saves from other sessions when auto-saving on game exit. It was possible for this to ruin one’s career progression

• Fixed shadows cast by terrain disappearing when turning around (introduced in #94)

• Added S060 locomotive
  • Small steam shunter, great visibility, high torque and medium range
    
  • Similarly to DM3, it’s more likely to spawn in smaller industries, like forests
• Simulated efficient coal management during accelerated steam engine startup
  • Halves the amount consumed
• Made partial shovel unloading possible
  
• Reduced cost of coal by 75%
  
• Reduced DM3 mechanical powertrain damage from engine running by 40%
  
• Fixed cylinder cock steam particles being out of sync with the piston cycle on S282
  
• Fixed reverser changing headlights orientation if the paired remote is off or in inventory
  
• Made some tweaks to Auto Headlights logic when using the “Direction” setting
  
• Removed accumulation of water in cylinders when the steam vehicle is in motion
  • IRL the tiny amount of condensing water gets expelled with each piston cycle
• Fixed S282 fire not going out when coal is exhausted
  
• Fixed firebox temperature not returning to boiler water temperature when fire is out
  
• Adjusted S282 so it doesn’t go over 120 km/h
  
• Reduced price of S282A/B subsystems (and thus repair costs)
  
• Added a new, heavier, wheel rolling sound for locomotives
  
• Fixed water in cylinders being audible at large distances
  
• Lowered dynamos sound volume
  
• Fixed exploded S282 retaining red valves and labels
  
• Added numbers to S282 sand gauge
  
• Allowed adding coal to firebox via the driving UI when the firebox doors are closed

• Added 9 new water towers to the map
  • Pass-through in FF, OWC, FM, GF, MF, FRC, FRS, MB
    
  • Non-pass-through in CSW
    
  • Maps have not been updated with new tower locations yet
• Made improvements to coal/water towers
  • Added alert sounds indicating steam vehicle alignment with chutes/faucets
    
  • Improved sound placement and volume, when using the towers
    
  • Fixed the water jet effect clipping through vehicles and taking too long to end
• Reduced intensity of cab lights in locomotives
  
• Fixed locomotives being able to despawn if coupled to an active order
  
• Fixed steam engine controls not resetting when paying fees (fire, injector, blower, etc.)
  
• Fixed text on comms radio sometimes getting stuck until put in inventory (introd. in #94)
  
• Aiming at locked vehicles in sandbox now notes that they need to be unlocked in career
  
• Tweaked audio mixing so the sound is less bassy in cabs
  
• Fixed hotbar mousewheel scroll direction being inverted
  
• Fixed main menu build badge button not leading to the news link on click

• Fixed some inconsistencies with Trigger/Grip usage (introduced in #94)
  
• Fixed Vive wands not using Trigger to interact with buttons (introduced in #94)
  
• Fixed held items being offset in left hand on some devices (introduced in #94)
  
• Fixed log getting spammed on some devices (introduced in #94)
  
• Improved interaction with rotary switches, notably the S282 exterior valves
  
• Removed recenter button in main menu, should only appear in-game
  
• Fixed carabiner slots resetting rotation on game load

• Fixed “vehicle must be stationary” false-positives when auto-starting quick tutorials

We just released a quickfix making teleport work again on the Reverb G2 VR headset, which broke with the #94 update.

More improvements soon!

Hi everyone!

It's great to finally talk to you from the other side of the Simulator update!

First of all, thank you all for the enormous amount of feedback, support and help following the release date! We read all your messages, and are adjusting our plans accordingly, even if sometimes we can't reply.

The 94% rating of Derail Valley and the 2600 simultaneous players peak at launch have topped all the current train driving sims on the market. Given our very humble beginnings, this really is the dream come true. The update release has been a great success so far, and we're hyped to bring you a lot more content and features to Derail Valley in the future!

Given the size of the update, naturally it didn't come without some issues. We'll be addressing them in the next couple of months. Today, we've released the first proper patch in the series of important fixes. Due to priority shuffling no new vehicles were added just yet, but the upcoming S060 steam locomotive is receiving final touches and will be released by the end of next week.

It's finally here! Three years since development on it started, we're pleased to announce the Simulator major update has just been released – along with a brand new trailer:

If you already have Derail Valley in your Steam library, it will be automatically downloaded. When you start the game your last save from the previous version will automatically convert to the new format and location used by Simulator. You'll then be able to continue from there, or start new sessions in the main menu – up to you!


We've made this listing so you can see what's new and what's coming soon:

For an early coverage of the new additions, check out Squirrel's exclusive preview videos! Some examples:

https://www.youtube.com/watch?v=976I6nF4tIw
https://www.youtube.com/watch?v=FY6vYX3cmq4
https://www.youtube.com/watch?v=aiGYzlmzoGU


Being an enormous update, a few things remain to be done. These are notably the S060 locomotive, DE6 slug, Steam Deck input layout (it does work otherwise), RailDriver support, and a couple more smaller things. Rest assured that the mentioned two vehicles will be added very soon, in a couple of weeks.


We've been making core changes to both until recently, and are happy to say that they are finished. The update features the all new S282 steam locomotive experience, as well as dynamic VR hands that naturally interact with controls and items. Support for the Pico 4 headset has also been added.


The update introduces 25 new languages to the game, translated by a carefully selected dedicated group of players. Apart from providing a good spirit and feedback, our translation team handled tens of thousands of words per language, and have put a lot of care into making it all fit nicely and using proper technical terms. They're absolute heroes!

We've marked the languages that we think the game is sufficiently translated to as supported on the store page itself. The rest are also available to choose from in the game, with an UI scoring element representing their completion level. Please let us know, and our translation team, how you like the translations and we'll further update the statuses.

Please bear in mind that since the tutorial translations needed to be done at the very end (today, also barring many bugs we've just resolved), they are also the least complete. Don't worry though, the translations will continue being improved after the release.


If you've been using mods, please note that you should to do a clean install of the game. If your save file was modded, it may not convert well – it depends. Most, if not all pre-Simulator mods will no longer work with Derail Valley and will have to be updated by the community in the coming weeks and months, to become functional again. Some of that effort is already ongoing.


For the next few days and weeks we'll make frequent updates, fixing all the immediate issues as they arise, as well as finishing up the two vehicles and a few more things. Then we'll drop the pace a little and take a well deserved rest. For the more long-term plans, please see our http://www.derailvalley.com/future/ page.

We hope you'll enjoy the new Derail Valley and where it's headed, and we're looking forward to seeing your reactions in posts, reviews, videos and other media!

Hi everyone!

For posts like these, usually there's a couple days of preparation. Today's post, however, is rather improvised, as everyone on our small team has been extremely busy with the upcoming release. There's a lot going on, and we wanted to give you a very quick update.

We're 30 days away from the definitive release date of Simulator, a big free update to the game. We're doing our best to have the update as complete as possible on that day. I'm sure something will not be entirely finished (there always is), but that's okay – we'll have a number of small updates following the release, to compensate for that. It's a huge release, after all.

Due to intense involvement with the development and the business side of things, I haven't been able to work on short videos at all this month, unfortunately. However, someone outside of Altfuture but very dear to us will hopefully satisfy your needs – with an episodic long-form video coverage of Simulator coming soon. Stay tuned!

In the past month we've made big strides on finishing the VR side of things and the tutorial. They're not done yet, but are close to the final stages. We've done a lot of further work on the steam engines and preparations for the new translators. As always, we've also been fixing a load of bugs, caught by our closed beta team, who had been also doing an amazing job translating Derail Valley to nine languages.

Today we're admitting dozens more people to the closed beta. The carefully chosen group will help us do the translations for 15 more languages and help us get VR calibration right for various types of headsets and controllers out there.

As the days get increasingly hectic, this may be the last you hear from us until the release. Soon you should start seeing new marketing material on our site, store fronts and social media pages. A new trailer will be be made and shown on the release day.

That's all for now! If you have any questions, please comment on this post and I'll try to reply to all. Thank you for your time!

Very exciting news today — The long awaited Derail Valley update, Simulator, is coming out on June 30th, 2023!

After several years being in development, the update will bring massive improvements to the game in the domains of graphics, simulation dynamics, user experience, bug fixes and future development productivity! You can see a lot of what's coming previewed on our YouTube channel.

An update of this scale can always be further improved, however, we've done enough preparations and testing over the years, both internally and with the closed beta testers, to safely conclude that any further improvements can be made after the release.

Simulator is a major stepping stone towards our even more grandiose future plans, that we've just recently outlined on this new page: http://www.derailvalley.com/future/


As we've made this massive update entirely from the game's sales so far — we'd like to say thank you to everyone who has supported us over the years!

In order to help fortify our next actions, we are ending the early supporter price period. The price of Derail Valley will go up for new customers, starting May 12th, 2023 at 19:00 CET, to $39.99 USD, or a region-tailored equivalent in other currencies.

We announced this change back in 2020, and now, more than four years after the initial barebones version of the game was released, we feel the change is justified. The team is now double the original size and all that time was spent working full-time on new features and content. Derail Valley has come a long way since, and it is especially the upcoming Simulator update that is driving the sales nowadays, with even more exciting coverage as well as a new trailer coming up in the following months!

If you're in position and willing to support our team for further development, please consider buying the game at the new price. If you'd like to buy it at a lower price, however, we've kept a time window for you until the 12th.

If you're wondering about the Early Access status - the game will remain in it, potentially, for years to come. This is because we want to add more features and content going forward, despite the product being stable and well rounded in its current form already. We'll keep at it for as long as possible, in our mission to make Derail Valley the best train simulator in the world.


April's been absolutely packed with work and we haven't had the chance to produce that many shorts this month. Next recap will, however, cover both April and May. In the meantime we've done a ton more bug fixing, finishing the UI, improving the translation workflow and have started work on the tutorial. The translation and closed beta teams have done a phenomenal job translating and finding bugs so far — thank you guys! We are about to start translating the second batch of languages soon.

That's all for today, we'll see you soon with more exciting content!
