TrainsRunner input data

The TrainsRunner simulator allows modeling a complex railway network, composed of a set of interconnected lines. Each line consists of one or more track, each characterized by the following data:

  • vertical alignment profile (slopes),
  • horizontal alignment profile (curves),
  • tunnels,
  • speed limits (for one or both direction),
  • stops name and position (for one or both direction),
  • traffic lights and traffic light control box.

The train model is characterized by the following data:

  • Length,
  • Tare, payload, Rotating masses percentage,
  • Maximum speed, Maximum acceleration and deceleration,
  • Motion resistance coefficient: constant, linear, quadratic (outdoors and in tunnel),
  • Curve resistance coefficient,
  • Braking type: dissipative or regenerative,
  • Traction effort, Total barking effort and electrical braking effort curves vs. speed,
  • Traction and Braking Efficiency curves vs. speed,
  • Minimum and maximum pantograph voltage, Rated pantograph voltage,
  • Average power of auxiliary loads,
  • Curves of maximum absorbed current and maximum regenerated current vs. pantograph voltage,
  • The curve of power factor vs. speed (AC train only),
  • Distribution of masses on the length of the train.

The DC power supply system model is defined by:

  • tracks sections, each characterized by the resistance of positive and negative circuit and by the conductance to earth.
  • a set of electrical substations, characterized by:
    • the rectifier (AC/DC converter) characteristic,
    • an arbitrary number of feeders,
    • Internal nodes and circuit breakers.
  • the following additional components:
    • Network nodes
    • Network breakers
    • Parallel cables
    • Electrical branches
    • Junction between lines
    • Line Isolators

The AC power supply system model allows to describe standard AC systems: 1x15 kV at 16.7 Hz, 1x25 kV at 50Hz or 60 Hz, 2x25 kV at 50 Hz or 60 Hz, composed by:

  • track sections modeled with an impedance matrix composed of any number of conductors,
  • a set of technological site characterized by:
    • Transformers
    • Auto-transformers
    • Breakers
    • Feeders
    • Ground Mesh
    • Electrical nodes
    • Electrical branches

The train operation data are defined by:

  • The train route, defined as a sequence of line sections:
    • for each route section, it’s possible to define the driving style: all out mode or coasting,
    • for each train route, it’s possible to define the starting speed, the headway and the synchronization.
  • The schedule of each train, characterized by:
    • the route,
    • the set of dwell times at stations or the arrival and departure time with the minimum dwell time,
    • the inversion time at terminus,
