Change value from other object

Hi. I have two arrays of Instantiate objects. One is for stations, and other is for connecctions. First I spawn the stations, and later I want to connect stations. What I do is instantiate an object between two stations, the connection have two variable (A,B) for know from and to where is the connections. The problem I have is trying to change the values of that variables. I get all the time the error CS1061 and I can't figured out.

 void connectStations(){
     for(int i = 0; i < stations.Length; i++){
         GameObject pathWay = trailSample;
         Vector3 otherStation = selectRandomStation();
         Vector3 position = stations[i].transform.position - otherStation;
         paths[i] = Instantiate(pathWay, stations[i].transform.position, Quaternion.identity) as GameObject;
         paths[i].pointA = stations[i].transform.position;
         paths[i].pointB = otherStation;
     }
 }

And this is the code for the connection

 public Vector3 pointA { set; get;}
 public Vector3 pointB { set; get;}

 void Awake () {
     pointA = Vector3.zero;
     pointB = Vector3.zero;
 }

 void OnDrawGizmos(){
     Gizmos.DrawLine (pointA, pointB);
 }
