Parcel Simulator now contains two different logistics problems. The original warehouse inspects parcels and sends valid cargo to Road, Rail, Air, or Maritime exits. The new Regional Sorting Centre, released on July 21, 2026, replaces that final cargo split with country-specific Express exports and a Country Calendar that changes every Monday. A belt plan copied from a launch guide can still teach the inspection chain, but it cannot be dropped unchanged into the new building.
This guide builds one dependable route through both problems: make the manual desk profitable, convert it into a testable inspection spine, add storage only where a shipping schedule demands it, scale the original warehouse without one giant bottleneck, and then migrate the same logic into the Regional Sorting Centre without carrying over the wrong calendar. Research was frozen on July 21, 2026. The official release post does not assign a public version number to the new warehouse update, so the date and live in-game rules are the version boundary.
Choose the warehouse before copying any layout
| Facility | What the final sorter reads | What controls dispatch | What not to copy into it |
|---|---|---|---|
| Original warehouse | Cargo type | The live Road, Rail, Air, and Maritime acceptance display | A twelve-country export tree |
| Regional Sorting Centre | Destination country on Express parcels | Programmable export doors and the Country Calendar | The original cargo-day rack plan or a fixed Monday-to-Sunday chart |
The inspection problem remains recognizable in both facilities: a parcel can fail its label, weight, serial number, country, cargo, stamp, or prohibited-content checks before it is ready to export. The destination problem changes. Keep those two layers physically and mentally separate. A valid/invalid decision belongs upstream; a cargo or country decision belongs downstream. If a package is being routed by destination before every required inspection has a result, the system is difficult to test and expensive to rebuild.
Use the first desk to learn the states automation must reproduce
Do not rush through the manual opening as if it were dead time. Each parcel should leave the desk in one of three states:
- Denied: at least one active criterion failed, so the parcel needs a denial sticker and an invalid exit.
- Approved and dispatchable: every active criterion passed and the correct destination is accepting parcels now.
- Approved but waiting: inspection passed, but the appropriate scheduled route is closed. This parcel needs storage, not a different sticker.
Keep the tablet open whenever the day’s rules change. Read the current cargo or country entries instead of working from memory, then check the parcel in a consistent order: destination and flag, cargo type, weight class, serial number, stamp, and contents requirement as those licences become active. The exact order at the desk matters less than never silently skipping an active rule.
Two launch-era beginner references agree on a useful cash discipline: stage correct parcels and submit full groups of eight rather than feeding the exit one at a time. Keep approved and denied piles visibly separate so a bonus batch never becomes a mixed decision. Trucks stop bringing new work at the evening cutoff, but parcels already unloaded can still be inspected; use that quiet period to clear the desk rather than beginning the next day with an unidentified pile.
The first purchases should remove a verified manual bottleneck. The Industrial Scale and weight licence teach the first extra criterion and open the early expansion path. Conveyor Deliveries removes repeated truck unloading. A scanner is valuable only when the belt around it can preserve both its valid and invalid outputs. Buying floor space, decorations, or a disconnected pile of machines before this loop is stable makes the warehouse larger without making it safer.
Build one inspection spine before connecting every incoming door
Start automation with one incoming lane and make it pass an intentional test set. The practical original-warehouse spine has four layers:
- Sticker triage: a Sticker Checker separates parcels that already carry an approval or denial from parcels that still need inspection.
- Verification: unstickered parcels pass through every scanner required by the licences currently active. Each scanner keeps the valid path moving and ejects a failure to the invalid side.
- Manual-content branch: the Contents Inspection Diverter removes packages that require opening instead of pretending a normal scanner has cleared them.
- Final marking: a valid line receives approval; all failure branches converge on denial. Destination sorting begins only after this point.
Scanner output sides can be chosen when a unit is placed. Make all invalid sides face a short common rejection corridor and let the valid line continue forward. This is easier to audit than weaving every rejection across the room. A test parcel that fails the first scanner and one that fails the last scanner should reach the same denied exit without ever rejoining the valid trunk.
Pre-approved and pre-denied parcels can bypass redundant checks while the Sticker Checker has enough capacity. That is an early- and mid-game optimization, not a sacred final design. A readable version 1.0.5.2 community build found that a max-volume Tier 14 warehouse could outgrow its Sticker Checker and used two parallel banks of the six ordinary verification scanners instead. Treat that as a topology to test, not a permanent throughput promise after the July 2026 update: if the queue grows before the sticker unit while the later scanners stay empty, the sticker branch is the bottleneck. If no queue forms there, keep the cheaper bypass.
Make rejection capacity before adding valid destinations
Rejected parcels can be produced by every scanner, while each valid parcel follows only one destination route. That makes the invalid corridor the first shared bottleneck. Build it before multiplying incoming doors.
Run one known-bad parcel through each active criterion. Watch it leave the relevant scanner, pass the denial sticker applier, and reach an invalid output. Then send a valid control parcel through the entire spine. A green result on the last scanner does not prove the system if an earlier red branch is blocked behind it.
Official patches changed several old troubleshooting assumptions. Update 1.0.3 made bridges queue parcels as three pieces and fixed scanner errors in automated builds. Update 1.0.5.2 fixed most reported stuck-joiner cases, multiple loaders attached to one rack, parcels trapped at scanner entrances after a reload, and parcels marginally below the next belt. Update the client before dismantling a sound design, then locate the first stationary parcel. A belt that appears stopped may be waiting on a hidden package, a full rack, a blocked chute, or an output that is not accepting the parcel’s category.
Sort valid parcels only after the inspection decision is final
In the original warehouse, send approved parcels into Cargo Type Diverters. A simple first split can peel Road and Rail from the trunk, then separate Air and Maritime downstream. Do not merge the high-volume routes simply because they end at nearby doors. Shared belts are useful only while their combined arrival rate remains below the slowest component after the merge.
Put Pauser Conveyors where one person can verify them at the beginning of the day. The live acceptance display is the authority. If a cargo route is closed, pause its unloader or final feed and let its rack absorb new parcels. When the route opens, confirm the exit before releasing the stored queue.
A dangerous design is one export gate reused by different scheduled types while a partial batch remains inside it. For example, if a gate holds Maritime parcels at the end of one day and is switched to Air the next morning, the first Air boxes can complete a mixed submission and turn yesterday’s otherwise valid stock into mistakes. Give a shared gate one persistent type, or completely empty and verify it before changing the assignment.
Storage is a time buffer, not an answer to every jam
A rack belongs between a valid destination split and a scheduled output. The loader fills it while that route is closed; the unloader releases it when the route is open. Smart Splitters can feed multiple racks because they ignore unconnected sides, while configurable diverters can give more precise priority as an array grows. Neither fixes an inspection bottleneck upstream.
Size storage from observed backlog rather than a copied endgame count. Start with one complete closed period for that route, then add a safety margin. Count how many slots remain just before the next opening. If every rack is full but the input scanner line is clear, add destination storage. If racks are half empty while boxes stop before the loader, inspect the loader, pauser, path, or rack assignment instead.
Keep loaders and unloaders accessible. Racks create a clean boundary for testing: pause the unloader, verify that the loader fills the expected rack, then reverse the test. A giant interleaved rack field may look efficient, but it hides whether a parcel is waiting because of the calendar, a full destination, or a routing mistake.
Scale Tier 14 by duplicating proven modules
The original warehouse expands through fourteen tiers and eventually exposes five incoming doors. Do not join all five entrances into one scanner line and call the result automation. A single merge makes every truck depend on one Sticker Checker, one copy of each scanner, and one invalid junction.
First clone the proven inspection module for each incoming lane that is actually creating a queue. Next, split high-volume valid cargo before merging it across doors. Finally, distribute invalid traffic between available rejection outputs so one red corridor does not throttle the entire facility. Input racks can absorb short bursts, but their purpose is to smooth a temporary mismatch; if they fill a little more every day, downstream capacity is still lower than arrivals.
| First visible queue | Likely constraint | Test before rebuilding |
|---|---|---|
| Inside the truck or at the receiving door | Unloading path or input buffer | Disconnect later machinery and prove the first belt can clear one delivery |
| Before the Sticker Checker | Sticker triage capacity | Compare a bypass with parallel full scanner banks on a separate save |
| Before one verification scanner | That scanner’s speed or a blocked invalid side | Watch both outputs; upgrade or duplicate only the constrained stage |
| At the invalid merge | Too many failure branches sharing one corridor | Route half the branches to the second invalid output |
| Before a rack loader | Full storage, closed route, or loader path | Read the schedule, rack capacity, and pauser state in that order |
| At an export door | Wrong category, mixed carryover, or full partial batch | Stop the feed and inspect the door display before changing a diverter |
Use launchers for a measured crossing, not as a default cure for distance. Old map guides describe launch distance changing with upgrade level, but official Update 1.0.4 replaced that behavior. Power and angle are now adjusted on the launcher’s two screens; upgrading affects belt speed. Test the landing zone with the lightest and heaviest parcel shapes you receive, and use divider walls if a valid trajectory can spill into another line.
Move to the Regional Sorting Centre on a copied save
The developer preview placed access to the new facility after reaching Tier 14 in the original warehouse. The released Regional Sorting Centre has almost five times the original warehouse’s total floor space, two levels, programmable export doors, and twelve country destinations. Express parcels must be routed by country, and the Country Calendar changes every Monday.
Use one of the new twenty save slots before purchasing or rebuilding. The safest first Regional Sorting Centre session is a commissioning test, not a maximum-throughput day:
- Open the live Country Calendar and record the current week inside the game; do not paste the original cargo schedule onto it.
- Configure one export door for one currently accepted country.
- Build or reuse a single inspection spine and keep one manual quarantine area for uncertain Express parcels.
- Send a known valid parcel to that country’s diverter and confirm the programmed door accepts it.
- Send a parcel for a different country and confirm it cannot leak into the tested output.
- Only then duplicate the country branch and begin assigning additional doors.
Pause country unloaders before the first Monday parcels enter the export tree. Re-read the new calendar, verify every programmed door, and release one lane at a time. A country rack that was valid last week may now be holding a closed destination. The Monday check is part of operating the warehouse, not an inconvenience to automate away with a permanent chart.
Give each new conveyor one narrow job
The July update adds tools that solve different spatial constraints:
- Country Diverter: makes the final Express destination decision. Keep it downstream of inspection and upstream of country storage.
- Speedway Conveyor: moves parcels across long open distances. It reduces travel time but does not increase the capacity of the scanner or door at the far end.
- Elevator Conveyor: transfers a line between the two floors and has adjustable direction. Treat each floor transition as a place to test flow, not as free storage.
- Pallet Build Mode: is purchased from the Upgrades tab and places conveyors directly from pallets. Use it after a small module passes its parcel tests, so rapid building multiplies a proven design rather than a hidden error.
A practical two-level design follows responsibility rather than symmetry. Keep inspection and its rejection escape paths together. Move long country trunks with Speedways. Use elevators where a defined country group changes floors, then provide storage close to its programmed doors. The official launch material confirms the machines and rules, but it does not establish one permanent optimal floor plan, exact country-to-door assignment, or stable weekly calendar. Let the live client choose those details.
Freeze a working state before chasing maximum throughput
A system is ready to scale when one parcel can be followed from arrival to a specific final state and every failure has an observable exit. Save at that point. Add one door, scanner bank, rack array, country group, or floor transfer at a time, then repeat the test. If mistakes appear, the last boundary added is small enough to inspect.
Three older reference claims should stay out of a current blueprint: fixed launcher distances by upgrade tier, a permanent original-warehouse cargo calendar for the Regional Sorting Centre, and a 24-achievement total. The current official count is 38 after fourteen achievements were added with the July 21 update. That count is useful as a version check, but an achievement route is a separate player task and is not substituted for the warehouse work here.
The goal is not the densest possible belt picture. It is a warehouse where rejection, inspection, destination, and calendar waiting remain separate enough to diagnose. Once those four states are visible, both the original cargo system and the new country system can grow without requiring a blind rebuild.
