So that anyone on the tracks knows a train is going to be coming out of the tunnel soon. Same as when the train exits the tunnel before coming into the WTC.
"Please do not attempt to board the train until it has arrived in the station. Thank you."
"Use Track 5 for the 5:17 local train to Raritan which has just departed."
