Beta Belasco Elevated Guideway 1.0

Belasco Elevated Guideway
Belasco's unfinished elevated railway, completed as the MRT Brown Line

This pack completes West Coast USA's unused elevated railway as the Brown Line of Belasco's MRT, a rubber-tyred AGT line (automated guideway transit: small driverless trains on rubber tyres, steered by guide rails along a concrete guideway, like the shuttles at many airports). When the level loads, it swaps the elevated viaduct and the suspension bridge segments for copies without their old rails, and lays a double-track, side-guided guideway along them, across the bridge and onto the island. The map files are not changed on disk.

Built for the Cherrier Anemoi APM 101 (also by me), but open to other vehicles. Without a train installed, the guideway and stations are still there to explore.

The line

• Three stations: Downtown BR01, Canal St. BR02 and Island BR03, with platforms and stop marks
• Side guidance: a wall on each side of every track, with a steel guide bar on its inner face and two power rails above it
• A crossover near each end of the line (for show; trains cannot use them)
• Line traffic: with the game's traffic switched on, one train runs on each track at a steady speed and turns back at the ends

Spoiler: For vehicle and script makers

Internally the line is called wcusa_agt; the paths and names below use that.

Adding a vehicle
A vehicle opts in to the line with one small JSON file in its own mod:

Code:

/lines/wcusa_agt/vehicles/<your_model>.json

Code:

{
  "model": "your_model",
  "refZ": 0.72,
  "halfLength": 20.67,
  "straight": 0.004,
  "traffic": {
    "speed": 9.72,
    "config": "default",
    "cmd": "controller.getControllerSafe('your_controller').setTarget(%s)",
    "model": "your_model_lite"
  }
}

• model: the jbeam model name. When this vehicle is spawned or reset near the line, it is put on the nearest track, facing that track's direction of traffic.
• refZ: height of the vehicle's ref node over the running surface (m)
• halfLength: half the vehicle's length (m); used for spacing and to keep it clear of the buffers
• straight (optional): for long guided vehicles placed as one rigid body. The vehicle is moved to the nearest stretch where the line stays within this distance (m) of a straight chord over its whole length.
• traffic (optional): lets the vehicle run as line traffic. speed in m/s, cmd is vehicle Lua that sets the target speed (%s is replaced by it), config is the .pc to spawn. model is an optional simplified stand-in for the traffic trains, which needs its own JSON file as well.

Guideway dimensions (lateral from the track centre, heights over the running surface, in metres)

• Running surfaces: centres 1.88 apart, 0.56 wide
• Guide bars: face at ±1.26, 0.04 thick, from 0.06 to 0.24; guide wheels bear outwards on both bars
• Power rails (750 V DC, visual): contact face at ±1.22, negative 0.34–0.41, positive 0.48–0.55
• Clearance: ±1.42 wide up to 3.8 m, but only 3.64 m in the island tunnel
• Max grade 8 %, cross slope up to 0.10 over the gauge

Line data for scripts (driver modes, timetables): /art/shapes/wcusa_agt/wcusa_agt.json

• tracks.A / tracks.B: points as [s, x, y, heading, roll, z, pitch], stops (stop-mark positions along each track, s in m) and buffers
• running: {"A": 1, "B": -1}, the direction of traffic on each track
• The GE extension wcusaAgtLine provides putVehicle(vehicleId, track, s) to place a registered vehicle with its centre at s
