A driver command that allows AI train to couple to the first vehicle standing in front of (or behind) a selected signal. If the vehicle is facing the signal lights, then the vehicle is understood to be in front of the signal. Otherwise, the vehicle is considered to be behind the signal.

PREREQUISITES: NONE
NOTES: The command works just fine if there exists no junction between the selected signal and the vehicle targetted for coupling . However, in case there exists a junction on the path between the selected signal and the vehicle, make sure that the junction does NOT block the path. You may need to change the junction direction in order to maintain the path. There are commands/rules already available on DLS to change junction directions.
