How to use

There's three methods in this module.

getStationInfo

Gives you station's departing and arriving trains. You need to use code name of the station. For example, Lahti is LH.

  var vr = require('vr');

  vr.getStationInfo('LH', function (info) {
    console.log(info);
  });

getTrains

Gives you all trains that are on the tracks at the moment.

  var vr = require('vr');

  vr.getTrains(function (trains) {
    console.log(trains);
  });

getTrain

Gives information about the stations that the train with given guid goes by. Also gives latitude/longitude, speed and direction of train. (Use guid from getStationInfo/getTrains in this.)

  var vr = require('vr');

  vr.getTrain('S79', function (train) {
    console.log(train);
  });
