100 kg — 2025 pre-alpha

Official messaging calls ammunition a luxury, but named calibers and stack sizes have not been published.

The official reveal trailer shows five quick-access slots, a 25-slot personal storage grid, and a 100 kg carrying limit. These figures belong to the visibly labeled pre-alpha build and may not match the 2026 Closed Beta.

Shown equipped inside the train and in the locomotive cab. Its construction and repair interactions are not fully documented.

Shown equipped beside powered train machinery in the official Steam gallery.

Shown equipped during the dungeon objective “The Trial Below.”

Used on salvageable objects at points of interest to recover better materials.

A reworked item-repair system uses dedicated repair workstations; component details are not public.

Steam categorizes Frostrail around inventory and resource management. Recovered supplies must support both away-team equipment and the train's continuing operation.
The 2025 reveal trailer's pre-alpha interface shows five quick-access slots, a 5 × 5 personal storage grid, a displayed load of 3.2 / 100 kg, and a Metal Container with a 5 × 4 grid. It also shows example stacks of 14, 5, 4, 8, and 36, but the item icons are not labeled clearly enough to assign canonical names.
These are archived interface figures, not current balance promises. Current item weights, stack limits, rarity rules, vendor prices, and final slot counts still need a playable 2026 build.

The April playtest included a tutorial, two exploration areas, weapon and essential-item crafting, and wildlife hunting for food. The currently live Closed Beta may show more than that early test, but its public announcement does not publish item cards, stack limits, recipes, or drop tables. Those fields remain open until they can be read from the game itself.

A complete official item list is not available yet. The 2025 inventory values describe an archived build, not the completed August–September Beta or the upcoming October demo. Check the inventory layout and carrying limit in the demo before planning how much your crew can bring back.

The community Beta database now has named records beyond the official screenshots. The entries below are reported values, not independently checked balance data: the pages do not identify a build ID or provide a screenshot for every field. Check your in-game card before spending materials, and do not combine them with older official screenshot values.
Frostrail is still in development. Names and values shown here are tied to published game material, while unfinished recipes, drop rates, costs, and balance numbers stay marked as unpublished until players can verify them in a live build.
