Train upkeep
Stash Upgrade Capacity
Expand storage container capacity through the Research Table’s Stash Upgrades chain.
WHERE & HOW TO FARM
Stash Upgrade Capacity
Stash Upgrades branch at the Research Table; capacity applies to train storage containers.
Before you go
- A Research Table aboard the train.
- Storage containers already placed on the train.
- Resources shown in-game for the next available Stash Upgrade tier.
Farming steps
- Open the Research Table and locate the Stash Upgrades chain.
- Select the next available tier and review its current displayed cost.
- Gather the listed inputs and complete the research.
- Follow any construction or activation instruction shown for that tier.
- Open a train container and confirm the added capacity rows.
- Sort gathered resources into containers and clear loose items from the deck before gates.
- The chain has four levels, but use the in-game display for current costs rather than relying on remembered recipes.
- Relocate containers with the hammer if their placement makes the new storage awkward to use.
Repeat, collect and use
Repeat through the available upgrade tiers; capacity research is limited to the chain’s tiers, not a renewable material farm.
Common mistakes
- Looking for a separate capacity item when the upgrade is in the Research Table chain; check the technology branch.
- Assuming an unlock is free to build; follow any displayed build or activation step.
- Leaving valuable overflow on the deck; store it before a gate barrier.
When to stop or switch
Stop researching this chain when all available tiers are complete or when another progression upgrade has higher immediate value.
