- A parent class for track related items such as junctions, signals, trackmarks, triggers or vehicles.
- Methods generic to all trackside items are provided within this class
- Although more specialised trackside items such as signals and junctions are catered for with appropriate child classes, there is no child class for speedboard items.
- GetSpeedLimit() can be used to determine weather a Trackside object is a speed board or not.

- Details of messages sent and received by Trackside objects are listed in the appropriate child classes.
BeginTrackSearch
public native GSTrackSearch BeginTrackSearch(bool direction)
- Parameters
- direction = Direction to search in based on the orientation of the Trackside item relative to the track to which it is attached.
- Returned Value
- A GSTrackSearch object which can be used by GSTrackSearch methods to conduct searches in the specified direction along the current track.
- Syntax
GSTrackSearch gst = BeginTrackSearch(true);
- Notes
- See GSTrackSearch Code Examples for a more detailed example of usage.
GetIsSearchLimit
public native bool GetIsSearchLimit(void)
- Parameters
- None
- Returned Value
- True if the current object is an AI Direction Marker, false otherwise.
- Syntax
if (GetIsSearchLimit()) Interface.Print("Track direction marker found");
- Notes
GetSignalState
public native int GetSignalState(void)
- Parameters
- None
- Returned Value
- One of the Signal State constants representing the current aspect of a signal.
- Syntax
int aspect = GetSignalState();
- Notes
- This method will return GREEN, YELLOW or RED, but will never return AUTOMATIC.
GetSignalStateEx
public native int GetSignalStateEx(void)
- Parameters
- None
- Returned Value
- One of the Extended Signal State constants representing the current aspect of a signal.
- Syntax
int aspect = GetSignalState();
- Notes
- See Signal for further details.
GetSpeedLimit
public native float GetSpeedLimit (void)
- Parameters
- None
- Returned Value
- The speed limit associated with this object in metres per second.
- Syntax
float limit = GetSpeedLimit();
- Notes
- If the object is not a speedboard a zero or negative value is returned.
- Returned values are in MPS, use the conversion factors in the train class to convert to other units.
GetTrack
public native Track GetTrack(void)
- Parameters
- None
- Returned Value
- The track segment that the current object is located on.
- Syntax
Track track = GetTrack();
- Notes
InnerReEnter
public native bool InnerReEnter(int node)
- Parameters
- node = Node Id of a train to be re-entered into inner trigger radius.
- Returned Value
- True if any part of the train is within the inner trigger radius at the time of the call and the message has been sent, false otherwise.
- Syntax
InnerReEnter(train.GetId());
- Notes
- The effect of this method is to cause a new Object,InnerEnter message to be sent from the train to this object.
ReEnter
public native bool ReEnter(int node)
- Parameters
- node = Node Id of a train to be re-entered into the outer trigger radius.
- Returned Value
- True if any part of the train is within the outer trigger radius at the time of the call and the message has been sent, false otherwise.
- Syntax
ReEnter(train.GetId());
- Notes
- The effect of this method is to cause a new Object,Enter message to be sent from the train to this object.
RequestTrackPermit
public native Permit RequestTrackPermit(bool direction)
public native Permit RequestTrackPermit(bool direction,GameObject owner)
public native Permit RequestTrackPermit(bool direction,GameObject owner)
- Parameters
- direction = Direction required by the Permit.
- owner = The object which is to own the Permit, to which any relevant messages are sent.
- Returned Value
- A Permit object for the track on which the current object is placed and for the direction specified.
- Syntax
Permit permit = RequestTrackPermit(true);
- Notes
- If the Trackside object is not on a track a null result may be returned.
- In other cases a Permit object will always be returned, but may or may not be Granted.
SetSpeedLimit
public native void SetSpeedLimit(float limit)
- Parameters
- limit = Speed limit to set, in metres per second.
- Returned Value
- None
- Syntax
SetSpeedLimit(100.0)
- Notes
- Use the conversion factors in the train class to convert from other units.
- This method allows the speed limit of a trackside item that is a speed board to be changed.
- Using this method for a variable speed limit sign is not fully supported and behavior is not guaranteed.
- It is generally best not to use or rely on this method. (There's confidence for you)
- Use a value of zero or less to rescind an existing speed limit.
