| Unity Security Patch | 2025-10-04 | Hey everyone!About This PatchWe have a small and quick update today. Two days ago, Unity, the game engine that Derail Valley is based on, announced a newly discovered security vulnerability and a patch for it (more info here).We included the patch in Derail Valley today, for increased safety. No confirmed exploits have been observed so far in any Unity-based games, so no one should be affected - this is just precautionary.That said, we advise you all to update the game as soon as possible, now that the vulnerability is publicly known. This update doesn't include any changes to the game itself, only the engine.About Build 100While we're here, |

| B99.4 - New Gadgets, Items, Paint Jobs, Control Binding, RailDriver® & More | 2025-04-19 | Hello everyone! We've just released a new update, bringing some new content, features and numerous other improvements to the game. Here are some of the highlights: Item Containers We've added item containers, which let you better store, organize and carry your items. Item containers provide extra inventory space, each with their own pros and cons when it comes to capacity and cumbersomeness. Proximity Sensor/Reader & Defect Detector Proximity Sensor and Reader gadgets make shunting long trains easier. Attach sensors to couplers at the ends of your train, put a reader in your cab, and know how far you are from trains in your way, both ways. No |

| B99.3 - Quick Fixes | 2024-12-10 | Hello everyone, We just released a small patch to fix a critical saving bug introduced a few days ago. For players who had items placed in hangers or sticky tapes mounted somewhere outside of trains, the game wasn't able to save progress. The number of affected users should be small, but the issue still warranted the hotfix. The patch also includes a couple more bug fixes we made in the past two days. You can see the changelog here: https://www.derailvalley.com/changelog Thanks, -Your DV Team |

You can see more about what's new here: http://derailvalley.com/changelog We're now working on the next patch, which, unless an urgent fix gets in the way, will take a bit longer to do but also be a bit bigger. Thanks for reading and see you soon! -Your DV Team |

| B99 - Release Date Announcement | 2024-11-12 | Hello everyone! This is a quick post to let you know that the next Derail Valley update that we've been working on since the start of the year, B99, will be released on November 21, 2024! The update will be rather large, introducing a couple of new stations, some train customization features, a new rail vehicle and many more improvements. We'll dive into showcasing the essentials in a long-form video that will be posted on the release date, alongside the screenshot above — unblurred. Rather than stick to an arbitrary date, we took the time to properly finish this update after we understood better what it really should be. Unfortunately that m |
| B98 - Microshunter, DE Revamp, Vehicle Catalog, Better FPS and More Improvements | 2024-02-09 | Hi everyone! We've just released build 98, our latest update bringing you a new vehicle, new features, numerous improvements and bug fixes! BE2-260 Microshunter 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 tre |
| Build 97 - Farm animals, stock car, VR mouse mode, major bug fixes & more! | 2023-11-10 | Hey everyone! We've just released a massive update, bringing numerous new features and bug fixes to Derail Valley. Domestic animals & new cars 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 react |
| Build 96 - Slug, texture streaming & many more improvements | 2023-08-18 | Hi everyone! We've just released the new update, featuring the new DE6 Slug and many other improvements to the game! Slug What is the Slug? 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. |
| Build 95 - New steam loco, water towers, VRAM optimizations & more! | 2023-07-21 | Hi everyone! The new update is out, introducing a brand new steam locomotive to Derail Valley, as well as many bug fixes and improvements! S060 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 optimiz |
| Reverb G2 Teleport Fix | 2023-07-16 | We just released a quickfix making teleport work again on the Reverb G2 VR headset, which broke with the #94 update. More improvements soon! |
| Build #94 - RAM Usage, UI selection, VR buttons & more fixes! | 2023-07-15 | 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 |

| Simulator - 30 days to go! | 2023-06-01 | 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 a |
