Transport Fever 3 cargo line planner
Match the whole cargo journey, not just its fastest leg. The Transport Fever 3 cargo line planner compares supply, demand and each leg's vehicle capacity to find the limiting stage.

Your planning result
End-to-end cargo throughput
Leg A is the first transport bottleneck.
- Demand not served
- 60 units / hour
- Lowest transport-leg capacity
- 180 units / hour
- Supply beyond delivered throughput
- 120 units / hour
- Leg A transport capacity
- 180 units / hour
- Leg A required fleet
- 4 vehicles
- Leg B transport capacity
- 240 units / hour
- Leg B required fleet
- 2 vehicles
- Leg C transport capacity
- 240 units / hour
- Leg C required fleet
- 4 vehicles
Calculation method & limits
A leg's hourly output = vehicles × capacity × load factor × 60 ÷ cycle minutes. End-to-end throughput is capped by supply, demand and every active leg. Required vehicles use the smaller of supply and demand as the target, rounded up independently on each leg. One to three sequential legs share the same cargo unit. This compares capacity; it does not simulate factory recipes, transfer eligibility, shared traffic or delivery expiry.
Balance transfers with the Transport Fever 3 cargo line planner
The Transport Fever 3 cargo line planner sizes a connected journey across one, two or three transport legs. A truck feeder, railway trunk and final delivery connection can each look adequate in isolation, yet the slowest stage determines what reaches the customer. Enter the same cargo unit and hourly basis across the entire plan. Supply comes from the producing industry and demand from the receiving destination. This cargo line planner highlights the gap between available production, transport capacity and completed delivery before you invest in a larger fleet on the wrong leg.
How to use this Transport Fever 3 calculator
- Choose the number of active legs and enter the source supply and final destination demand per hour. Extra legs are ignored when disabled. Keep transformed products separate: raw logs and finished planks belong to different transport tasks.
- For each active leg, enter current vehicles, vehicle capacity, measured round-trip minutes and achievable loading. Include return travel and terminal service in that cycle; use the station calculator if queues prevent that cycle from remaining stable.
- Read the bottleneck and required-fleet values from the Transport Fever 3 cargo line planner. Change one limiting leg first and compare end-to-end throughput, rather than adding vehicles to every connection at once.
A worked planning example
A source offers 300 units per hour and the destination needs 240. Leg A has three 30-unit vehicles on a 30-minute cycle at full loading, carrying 180 units per hour. Legs B and C each carry 240. End-to-end delivery is therefore 180 and unmet demand is 60. Increasing A to four vehicles lifts it to 240 and covers demand. If source production drops to 100, no amount of extra transport can deliver more than 100 units per hour.
What to do with the result
The cargo line planner shows a transport capacity comparison, not an assurance that a connection will load. Check cargo compatibility, catchment, connected terminals and destination acceptance in your save. Use the production-chain calculator for recipe inputs and by-products, the warehouse planner for stock accumulation and the delivery-time calculator for time spent transferring. These tools answer different parts of the same Transport Fever 3 cargo problem.
Calculator questions
Does the Transport Fever 3 cargo line planner calculate production recipes?
No. Enter the actual output rate of the cargo being transported. A factory converting one cargo into another requires separate transport scenarios; use the production planner to calculate the material quantities.
Can I plan a direct truck line without rail?
Choose one active leg. Two and three legs are for sequential transfers. The cargo line planner hides unused input groups and leaves their result rows empty, so imaginary transfer legs do not constrain a direct connection.
