LTN (Logistic Train Network) turns trains into logistic bots.
The 3-Stop System
LTN requires three stop types:
| Stop Type | Purpose | Circuit Connection |
|---|---|---|
| Depot | Idle trains wait here | None (LTN manages) |
| Provider | Items available for pickup | Storage chest 鈫?stop |
| Requester | Items needed for delivery | Requester chest 鈫?stop |
How it works:
- Provider signals available items to LTN
- Requester signals needed items to LTN
- LTN dispatches idle train from depot
- Train loads at provider, unloads at requester
- Empty train returns to depot
Depot Setup
The depot is where idle trains park. Critical rules:
- Minimum 2 trains —one loading/unloading, one waiting
- No schedule —LTN assigns temporary schedules
- Fuel station —trains refuel at depot automatically
Place depots centrally on your rail network. Every train should reach a depot within 30 seconds of emptying.
Provider Stops
Provider stops announce available items:
- Place stop next to production
- Wire storage chests to stop
- Set "provide threshold" (e.g., provide iron plates when >1000)
Best practice: Use passive provider chests. LTN will dispatch trains when stock exceeds threshold.
Requester Stops
Requester stops announce demand:
- Place stop next to consumption
- Wire requester chests to stop
- Set "request threshold" (e.g., request iron plates when <200)
Best practice: Use requester chests with high request counts. LTN batches deliveries to minimize train trips.
What Veterans Learn the Hard Way
- Depot trains must be empty —LTN can't assign a train carrying cargo
- Wire every stop —unwired stops break the network
- Thresholds matter —too low = train spam; too high = stockouts
- One item type per provider —mixed providers confuse LTN
Common Mistakes
| Mistake | Consequence |
|---|---|
| Single train depot | Network stalls when train is busy |
| Unwired stops | LTN doesn't see supply/demand |
| Mixed provider chests | Trains load wrong items |
| No fuel at depot | Trains strand mid-network |
The Bottom Line
LTN automates train logistics. Build depots with 2+ trains. Wire providers to storage chests. Wire requesters to requester chests. Set thresholds. Let LTN handle the rest.
