Cargo Not Loading? How to Fix Cargo That Won't Move

Quick answer: Transport Fever 3 stations and ports no longer store cargo the way they did in Transport Fever 2. Cargo only unloads when it has a valid destination — a factory that consumes it, an end consumer, or a warehouse. If nothing is unloading, check the destination first, then whether the route needs a warehouse, then the line's load/unload settings. The most common causes: the destination's demand is already full, there's no warehouse for a multi-leg transfer, or the line isn't set to load/unload that cargo.

Why TF3 cargo works differently from TF2

The biggest change from Transport Fever 2 is that stations and ports don't hold cargo as inventory. A developer (UG-Sam) confirmed this directly on the official Steam discussions: ports and stations no longer store cargo — you need a warehouse to handle transfer and storage, and cargo only unloads when it has a valid destination.

In TF2, cargo would wait at a station until a vehicle picked it up. In TF3, cargo only appears and unloads when the whole chain points somewhere real. This single change is behind most "cargo not loading" reports.

Quick diagnostic table

Symptom	Most likely cause	Check
Train / vehicle won't unload	No valid destination, or destination demand is full	#1
Fish won't unload	Destination demand already filled	#1
Port holds multiple goods, one won't move	Stations/ports don't store cargo — needs its own destination or a warehouse	#1, #6
Cargo stuck at a transfer point	No warehouse on the transfer leg	#6
Industry has cargo but station is empty	Catchment / road connection, or cargo not assigned to the line	#2, #7

1. Check destination demand

Cargo only unloads when it has a valid destination — a factory that consumes it, an end consumer, or a warehouse. The developer also noted that if a terminal building's demand is already filled, unloading stops. So "nothing is unloading" is often the game working correctly: the destination no longer needs that cargo.

Open the destination factory or town and confirm it still needs this cargo. If its demand is full, redirect the line to a destination that still consumes it.

2. Check catchment and road connection

The station or port must be connected to the industry by road and cover it within its catchment area. If the station is too far from the industry, cargo won't reach it. (Exact catchment ranges for the release build are being verified in-game.)

3. Check cargo category

The 37 cargo types fall into four categories — liquid, bulk, flatbed, goods — each with its own storage and loading. A cargo of the wrong category won't load onto the wrong facility, and a category can't be mixed arbitrarily on one platform.

4. Check vehicle compatibility

Not every vehicle carries every cargo. The Dev Blog states it's "more important than ever to keep track of which vehicles support which." Check the vehicle's supported cargo types before assigning it to a line.

5. Check the loading facility

Some cargo needs a specialised loading facility rather than a generic station. The First Look confirmed dedicated loading infrastructure for certain goods; a line serving the wrong facility type won't move its cargo.

6. Check warehouse / transfer

Because stations and ports don't store cargo, multi-leg routes need a warehouse for transfer and storage. If cargo stops mid-route, check whether the transfer leg has a warehouse.

Warehouse filters and their exact behavior are still being verified in-game — players report specific filter options for the release build, but these aren't yet confirmed in writing. Treat any filter advice as provisional until you see it in your own game.

7. Check line settings (load / unload)

TF3 gives you full control over loading and unloading on each line. If a line isn't set to load or unload a cargo, the vehicle skips it. The exact load/unload and "force unload" options are player-reported for the release build — verify the behavior in your own game rather than assuming TF2 settings still apply.

8. Check capacity and queue

Platform length, vehicle queue, and loading speed all affect throughput. Exact numbers for the release build are being verified in-game; a full platform or a long queue is the visible sign to look for first.

Common symptoms

Players are reporting these specific problems on Reddit and Steam:

Train won't unload — usually a destination or line-setting issue
Fish won't unload — the developer-named example of a full destination demand
Port holds multiple goods, one won't unload — stations/ports don't store cargo, so each good needs its own valid destination or a warehouse
Cargo stuck at transfer — missing warehouse on the transfer leg
Industry has cargo but station is empty — catchment/road connection, or the cargo isn't assigned to the line
