Development and Release

Railborn is developed and published by Washbear Studio, a small independent studio. The game is being built in Unreal Engine 5, which a developer identified in July 2025 as version 5.6, and is planned for release on Steam Early Access for Windows PC. Washbear Studio is an Epic Games MegaGrants recipient.

Announcement

Railborn was officially revealed at the PC Gaming Show on June 8, 2025. The reveal included both a short and a long gameplay trailer. The announcement confirmed the game's survival and train-building premise, its one-to-four player co-op support, and its Steam Early Access release plan.

Origins

The idea for Railborn is older than its announcement. The studio has said the original concept came out of an early prototyping event more than six years before the reveal, and was shelved at the time because the technology was not available to build the version they wanted. The design was picked back up roughly two years before the game was announced, which is when work on the current Railborn began.

Early Access Plan

Washbear Studio plans to release Railborn into Steam Early Access before completing it. The studio estimates the Early Access period will last one to two years. During this period, the team intends to share a public Trello development board with the community, conduct regular beta tests with early community members, and incorporate player feedback into the game's development.

As of August 27, 2026 the store page lists no price for the game. The studio has stated that the price will increase before the end of Early Access.

The studio has published what each version is meant to contain:

Alpha Playtest

In March 2026, Washbear Studio announced the first closed alpha playtest. The studio noted that testers should expect to see only small portions of the game in a rough state, as the playtest was intended to gather feedback on what was fun, identify bugs, and find rough edges. The team spent several weeks prior to the announcement stabilizing co-op after an update introduced synchronization issues with construction, player positioning, and shared resource management. The closed playtests have continued since then, with the studio adding testers from its sign-up list over time. A demo has been referred to alongside the ongoing tests since 2025, but none had been released as of August 27, 2026. Asked in July 2026 whether a playtest would coincide with a train-themed storefront event, a developer said the team had hoped to have a demo ready but that it had not worked out because other tasks on the main game came up, adding that with no publisher setting milestones the studio would not rush the game out in a poor state.

Platforms

Railborn launches on Windows PC via Steam. Mac and Linux are not supported at the Early Access launch. Asked directly whether the game would run through Proton or Wine on Linux, the studio replied that it did not know, and that it expected to find out once a demo or an Early Access build was available.

No Steam Deck compatibility rating has been issued for Railborn, and as of August 27, 2026 the store page shows no Deck status. The developers have addressed the handheld directly, however. On the day of the reveal, answering two separate questions about controller support, a developer said the game already ran well on a Steam Deck with a controller at that stage of development. That was a remark about a build in progress rather than a commitment to support the device, and it came roughly six months before the answer above about Proton and Wine.

Multiplayer Infrastructure

The developers have answered a few questions about how multiplayer is put together. The game uses Steam's own networking for its online play, and in mid-2026 a developer said there was a small chance the team would move to a different networking service, without committing to it.

Dedicated servers are not planned for the initial release. Asked about them shortly after the reveal, a developer said the studio would not do dedicated servers to begin with, but would revisit the question if there turned out to be enough demand. Sessions are therefore expected to run through the co-op setup described elsewhere rather than through servers players host themselves.

Steam Features

On Steam, Railborn is configured to use several of the platform's features. The Steam store page lists Steam Achievements and Steam Cloud saves, along with full controller support and Steam Family Sharing. As with other pre-launch details, the exact feature set may change before and during Early Access.

Language Support

Railborn supports 12 languages at launch, with interface support for English, French, Italian, German, Spanish, Japanese, Korean, Polish, Portuguese (Brazil), Russian, Simplified Chinese, and Turkish.

System Requirements

Minimum and recommended system requirements for Railborn have not been published. As of August 27, 2026 every field under both the minimum and the recommended specification on the store page still reads TBD, to be determined. The only concrete requirement stated is a 64-bit processor and operating system.

Wishlists and Storefront Events

Railborn drew attention quickly after its reveal. The studio reported passing 400,000 wishlists roughly seven weeks after the announcement, and said the response opened up more options for the project.

The game has since been featured in storefront events. It appeared in the Tiny Teams showcase in August 2025, which highlights games made by very small teams, and it was listed among the upcoming titles for the train-themed storefront festival that ran from July 20 to July 27, 2026.

Genre and Positioning

The studio classifies Railborn as an open world survival craft game. Alongside survival and base building, its storefront listing is tagged for automation, sandbox, first-person, science fiction, resource management, story rich and immersive sim.
