Read a chain from destination to source
Transport Fever 3 has 36 cargo items: 12 raw materials, 11 intermediate products, three booster products and ten end products. Its 32 industries include raw producers and processors with production rules. The exact industries available also depend on climate and map progression.
Start at the destination. A town district or industry shows what it accepts. Follow that item backward to its manufacturer, then follow every required input backward until you reach raw producers. This prevents the common mistake of transporting an item simply because it exists nearby.
Understand the industry window
The production section shows the recipe and recent throughput. Input stocks show whether required materials are arriving. Output stocks show what has been produced and is waiting for collection. Supplier and consumer lists help confirm whether the relationship you intend actually exists.
Raw industries can produce without input. Processing industries need the specified input stock. If output reaches its storage limit, excess production may be destroyed, so a high output stock is evidence of a collection problem rather than a reason to add more input.
Cargo specialization matters
Cargo items belong to specializations such as bulk, liquid, goods or flatbed. A vehicle that can travel the route but cannot carry the selected specialization is not a valid link. Check the vehicle’s accepted cargo before purchasing a fleet.
The terminal also has to accept and transfer the item. At mixed hubs, confirm that the road, rail, water or air components belong to the same usable station group and that the next line is configured for the cargo.
Boosters and workers
Industries can receive a throughput boost from passenger service that brings workers. Raw industries may also use booster products such as Fertilizer, Machines or Tools, depending on the industry. A booster is optional capacity, not a substitute for a working base chain.
Build and stabilize the main cargo flow before adding the booster. Otherwise a second incomplete route can make the original failure harder to diagnose.
A cargo-chain audit
| Check | What success looks like |
|---|---|
| Destination | The selected building, district or industry explicitly demands the cargo |
| Recipe | Every mandatory input is identified |
| Source | Output stock contains the expected item |
| Catchment | The terminal covers or connects to the industry or district |
| Vehicle | The cargo specialization is accepted |
| Line | Stops are ordered from pickup through every transfer to delivery |
| Capacity | Waiting stock and vehicle loads are reasonably balanced |
Why a chain stalls
If nothing is produced, check missing inputs. If production exists but nothing reaches the first station, check catchment and loading configuration. If cargo reaches a transfer and stops, check station grouping, the next vehicle type and unload or load rules. If the final terminal fills up, verify that its catchment reaches the actual consumer.
Do not start by adding vehicles. More capacity fixes only a capacity shortage; it cannot create a missing demand path.
