Verified history
This means HyperObserve has not found sufficient first-party evidence for a dated before-and-after event. It does not mean Railway has never changed. Undated values are kept in the current baseline below instead of being presented as history.
Current monitored baseline
HyperObserve currently monitors 2 scoped observations for Railway. The baseline covers persistent volume capacity, paid volume resize. Each value retains its plan, product, endpoint, region, account, or runtime qualifier so a future change can be compared against the correct scope.
| Constraint | Current value | Scope | Verified source |
|---|---|---|---|
| persistent volume capacityPaid plans can resize, and Pro offers a self-serve path up to 1 TB. | Free/Trial: 0.5 GB; Hobby: 5 GB; Pro: 50 GB | Plan dependent | RailwayAug 22, 2026 |
| paid volume resizeThe standard Pro volume size is lower and can be expanded on paid plans. | Pro self-serve up to 1 TB | Pro | RailwayAug 22, 2026 |
Tracked constraints and impact
Persistent volume capacity, plan tiers, resizing, and attachment constraints. A change is recorded only when it alters a constraint developers can act on, such as capacity planning, request shaping, model selection, deployment configuration, storage design, retry behavior, or account budgeting.
Railway Volume Size Limits by Plan

How a change is verified
- Compare the current first-party statement with the previously stored observation, including the exact plan, model, runtime, endpoint, region, and account scope.
- Separate a true product change from documentation clarification, temporary capacity, configurable account state, or a limit that applies to a different execution path.
- Preserve the old and new values, official source, effective date when disclosed, detection date, and practical impact. If those elements cannot be supported, no historical event is published.
Official sources monitored
These first-party documents support the current Railway baseline. HyperObserve links directly to them so you can confirm the live wording before making a production decision.
