Trains

  • Single resource: Only one item, or fluid per train, Massively simplifies schedules
  • Refuel: Interrupt refueling station, Can force upgrade the fuel type
  • Generic schedules: Use train groups, Use generic schedules using interrupts dependent on picked up cargo
  • Train limit 1: Replaces train stackers, Prevent train queues on the main track,
  • Bidirectional trains: Locomotives on both ends of the train, Allow more compact stations using terminus1 aka. terminal station

Pickup stations

  • Generic item, or fluid pickup
  • Buffer one train load (40 slots) per wagon, usually 4 chests limited to 10 slots each

Dropoff stations

  • Specific to one item, or fluid
  • Generic pickup stations
  • Train must always unload completely
    • enable stop entire buffer runs low (<1000 items)
    • multiple buffer chests per wagon
    • balance consumption between wagons

Rail tracks

  • Separate tracks per direction: Prevents deadlocks
  • Leave sufficient space for signals between lanes (6 tiles in 1.1)
  • Don’t align to grid: Grids are inflexible, Adapt to terrain
  • Build power lines, signals separately:
  • Rail planner: Don’t use blueprint aligned to a grid, Adapt your tracks to the terrain instead of landfilling and flattening it to fit your blueprint
  • Redundant routes: Bypass high traffic, if you temporary stop on main track
  • No main base: Distributed production if more expandable and spreads out traffic

Junctions

Deprecated

  • 4 directional lanes
  • left-hand traffic
  • path block are straight, t-junctions, curves, or stations
  • provider stations enable when a train could be fully loaded
    • minimun of stations to deposit all trains is always ensured
  • requester stations enable when a train could be fully unloaded
    • if demand surpases production, only 1 or 2 of the 3 stations enable, cycle through all requester stations and only assign one train the iteration
  • no roundabouts
  • no 4-way intersection
  • Build a rail network out of t-junctions instead of roundabouts
