Which Transport Fever 3 calculator should I use?
For a route that already runs, start with the Transport Fever 3 line planner and enter a measured round trip. Before construction, use the distance fleet calculator with an explicit transport period. If vehicles queue at a terminal, the station throughput calculator compares loading positions and service time. More vehicles only help when the route and station can process them.
Use the production chain & freight planner to connect target output, materials, dedicated fleets and per-cargo buffers in one plan. The cargo line planner checks serial-leg bottlenecks; warehouse and delivery-time tools explore storage and elapsed time. Keep production quantities and transport rates on one explicit time basis.
For a budget, combine the Transport Fever 3 income estimator with the route profit calculator on the same period basis. Vehicle comparison checks fleet running costs, while train consist planning checks mass, capacity and platform fit. The ownership cost calculator includes longer-term purchases and replacements; the loan and contract calculator compares explicit success and failure scenarios.
For a new save, the Transport Fever 3 map size calculator compares dimensions and land area using official standard-size presets. It does not generate terrain or certify a seed. The directory calculators use your observations and stated assumptions, so replace the examples with values appropriate to your map, route, difficulty and mods.
