Transport Fever 3 City Growth and Population Limits
Confirmed: the official pre-release city overview describes 18 growth levels and growth experience from passenger travel and required goods. Unknown: no checked source establishes a 5,000-person cap or a tested method for reaching one million people. Checked 29 September 2026, before Steam unlock.
Transport Fever 3 has 18 announced town growth levels. Passenger trips and required-goods deliveries award growth experience, with six town ratings affecting how growth works. The official sources checked do not confirm a 5,000 population cap or a one-million-person target/method.

What the official sources confirm
The official Tycoon developer blog describes 18 growth levels, starting with hamlets under 100 residents. Passenger journeys and deliveries of required goods award experience. The blog also says that longer trips between towns can award more passenger experience than travel within one town, and that cargo type and production-chain complexity affect growth experience.
Six town ratings influence the experience multiplier. The official overview names transport quality, traffic and environmental conditions among the growth considerations. These are announced mechanics from pre-release material, not results measured in a released build.
Is there a 5,000-person city cap?
No checked official source states a 5,000-person maximum. The 18 announced growth levels do not by themselves establish a final population cap, because no population values for the upper levels were published in the sources reviewed.
The developer says Sandbox mode can change a city’s size and can freeze city growth. That confirms Sandbox controls, but it does not state the numeric limits of those controls.
Can one city reach one million people?
A reliable answer is not available yet. The official material reviewed does not give a one-million-person target, a step-by-step method, or a verified population limit. Do not treat Transport Fever 2 behavior, community speculation or a search snippet as proof about Transport Fever 3.
Because Steam still showed a scheduled unlock at the observation time, this page has no launch-build test of city population. Recheck after the game is available and record the game version and settings before publishing a numeric result.

The official overview says passenger and cargo deliveries fuel town expansion, while reputation, passenger happiness, delivery timing, congestion, noise and pollution can limit growth. This is a pre-release description, not a tested launch-build result.
