Warehouse not transferring cargo?

When do you need a warehouse?

Urban Games says platforms, ports and stations do not store freight between lines. Its developer answer uses fish moving from a ship to a shore truck as an example: the handoff needs warehouse storage even if the fish leaves immediately. Freight delivered straight to a town or industry consumer is the stated exception. The developer also describes modular warehouses that store and transfer cargo and can specialize in four cargo categories.

Check the transfer in order

1. Identify the handoff. Name the line bringing cargo in and the line taking it out. If the first vehicle is empty, inspect its origin and loading point; the empty station guide covers that earlier fault.
2. Provide usable storage at the change of line. Put a warehouse in the actual connection/catchment of the incoming and outgoing cargo stops; visual closeness alone is not proof. Select the warehouse, open Stocks and inspect the row for each module: supported cargo, stored quantity and remaining delivery time. On a specialized module, click the cargo icons to choose its product. One release-player transfer began working after the receiving warehouse was filtered to Fish instead of canned food. The ship-to-truck fish guide covers its separate stop-direction fault. Exact connection distance remains unverified.
3. Run both legs. Check that the incoming vehicle unloads at the handoff and that a suitable cargo vehicle on the next line loads there. Follow one shipment, rather than assuming that a built warehouse proves the lines are connected.
4. Open the warehouse information window. The official gameplay overview shows stock and incoming/outgoing information. Watch whether cargo enters storage and then leaves on the next line. If turnover is immediate, the outgoing vehicle is the stronger success signal.

A second cargo type will not enter the warehouse?

The current manual distinguishes universal storage, which can mix cargo types, from specialized storage, which holds one product per module. Even Crude Oil and Fuel need separate Liquid modules. In Stocks, compare the arriving product with the selected module, its pinned product and free space before treating a loaded vehicle as a broken transfer.

1. Check the actual product and slot. Select the warehouse and compare its stored type with the cargo on the arriving vehicle. If the filter is pinned to the old product, choose the intended product for that slot only after deciding where the old stock should go.
2. Provide room for the second type. Add a cargo storage module in the same connected warehouse, or empty and repurpose an existing module if the old product is no longer needed. In the lettuce/fabric report, players suggested these alternatives; a separate fish/meat report resumed unloading after another warehouse was built. Use the current module description to distinguish universal and specialized storage; the reports are not a fixed capacity rule.
3. Verify one delivery. Watch the arriving vehicle unload, confirm the correct product appears in the selected stock slot, then watch an onward vehicle collect it. If stock remains unchanged, recheck road/catchment connection and the destination stop's load/unload setting before building more modules.

Unwanted chemicals occupy the oil vehicle?

In RossStudio's refinery case, Chemicals filled the vehicle that was supposed to collect Crude Oil. FlyingEagle_ and ChristBKK suggested warehouse filtering, but the author did not confirm a repair. Preventing another pickup and unloading cargo already aboard are two separate checks.

1. Stop collecting the unwanted product. In Line Manager, open Configure stop at the refinery and disable Chemicals for loading on the oil-feeder line. Keep Crude Oil selected at its intended origin. Inspect repeated stops too; changing a warehouse filter alone cannot remove chemicals already in the vehicle.
2. Provide a real place for the existing load. If you want to retain it, add a compatible Liquid warehouse module within the receiving stop's cargo catchment, open Stocks and select Chemicals for that separate module. Keep the Crude Oil module separate. At this unloading stop, disable Chemicals loading so the line is not told to retain or reload them.
3. Watch the complete recovery cycle. Confirm Chemicals leave the vehicle and appear in the chosen module, then check that the next origin pickup carries Crude Oil again. If they remain aboard, recheck free space, cargo highlight and the stop's capacity target before buying more vehicles.

This is a storage-and-filter workflow based on the manuals, not a claimed successful replay of that post. Stored Chemicals still need onward transport to a Chemical Plant if you want them used. A full factory output does not force you to collect every byproduct: the manual says excess output is destroyed while production continues. A warehouse Stocks row also has a discard control; using it destroys that module's stock and is not a paid delivery.

The destination is full?

If the arriving vehicle carries the right cargo and the connection works, inspect the actual receiving stock. A full factory input or transfer warehouse can leave cargo on the vehicle. Follow the full-buffer and oversupply checklist before adding another feeder or enabling forced unloading; discarding excess is not successful delivery.

How to tell it worked

Cargo arrives on the first vehicle and appears on the onward vehicle after the handoff. The warehouse's incoming, stock and outgoing display helps locate the break. A stationary building or an empty platform alone does not demonstrate a working transfer.

If the cargo still stops

• Incoming vehicle empty: check production at the origin, its actual loading point and the first vehicle's cargo category. Start with the pickup checklist.
• Vehicle carries cargo, warehouse receives none: check the destination stop's load/unload selection, the warehouse connection highlight, and whether its filter permits this product. Exact release-build connection distance is unverified.
• Another cargo already occupies the receiving module: check the pinned filter and stock, then add a connected module or clear/reassign an old slot. Preserve needed stock before changing its filter.
• Warehouse receives cargo, next vehicle empty: check the outgoing cargo stop, vehicle category and line loading direction. If the warehouse is specialized, check its category.
• Onward vehicle loads, delivery fails: follow that line to the receiving town or industry. The handoff itself is working; troubleshoot the destination separately.
