Transport Fever 3 vehicle maintenance starts with the vehicle's condition and the facilities its route actually reaches. A depot where you bought a vehicle does not by itself prove that its operating route receives maintenance. Diagnose the cause of reduced service before replacing the whole fleet.

01 / Start with the vehicle's own condition record

Inspect one affected vehicle and compare it with a vehicle performing the same task well. Record actual journey time, waiting, loading and condition. The official manual describes a Condition section with maintenance history and modifiers to vehicle properties. Vehicle details.

Our suggested baseline is one full circuit under similar demand. A queue or empty load can explain poor service even when maintenance is available, so avoid treating every slow trip as a condition problem. Use No Path troubleshooting for an unreachable route.

02 / Match maintenance facilities to the operating route

The station manual distinguishes purchase depots with a small maintenance radius from dedicated maintenance buildings with a wider radius. Dedicated buildings do not sell vehicles, and aircraft have no dedicated maintenance building. Depots and maintenance.

Follow the actual route and inspect the relevant coverage rather than measuring from the place you bought the vehicle. For a proposed facility, consider the passing route, space, cost and effects on existing infrastructure. The observed route is the useful reference, not a straight line drawn between endpoints.

03 / Know which symptoms maintenance may explain

Urban Games describes automatic maintenance within suitable facilities' range, with neglected fleets becoming slower and producing more noise and pollution. Official management overview.

Compare that description with your vehicle's displayed condition and modifiers. If the route is blocked at a junction, restored condition will not repair the junction. If the whole game struggles to render frames, use our performance diagnosis. Different symptoms can coexist; keep their observations separate.

04 / Test coverage before changing every vehicle

Save a copy and choose one representative service. Record its route and condition, make one coverage-related adjustment, and observe subsequent trips. Compare the same vehicle or an equivalent service under similar operating conditions.

Do not simultaneously add facilities, replace the fleet and rebuild the route. That makes it difficult to tell which change helped and what it cost. If you choose a detour to obtain coverage, compare the extra trip time and its consequences for capacity and deliveries. A maintenance improvement is useful only if the service still meets its purpose.

05 / Compare maintenance with replacement as complete choices

Create two plans: retain and maintain, or replace. Include purchase costs, expected running costs, added infrastructure and the value of vehicles you sell. Use the same comparison period for both plans.

For a purely illustrative example, a replacement with lower recurring costs may still be poor value if its initial cost is large and the current route is lightly used. Our ownership-cost calculator and vehicle comparison tool help organize those assumptions. They do not know your save's real costs unless you enter them, and they do not establish a universal replacement age.

06 / Verify condition and the service outcome together

After the change, check condition history, journey duration, loading and route costs again. Look for an improvement that persists over repeated trips, not just the first departure after editing.

If condition recovers but service remains poor, investigate the separate bottleneck: queues, path restrictions, load compatibility or low demand. If a longer maintained route produces late cargo, use the delivery-time guide to trace the trade-off. Keep the successful adjustment and its assumptions in your notes so that the next fleet decision is based on a comparable result.
