We all hope that there is light at the end of the tunnel. Some of us wait for the light patiently. And others of us wait for the light anxiously.
Seeking the light at the end of the tunnel can be a dangerous thing. That is, especially, true when the light you are longing for is the headlight of a train and the tunnel is a subway tunnel. In this case, patience is not only a virtue, but it can also be a lifesaver.
Before the installation of Public Address Customer Information Screens (PA/CIS) system, many New Yorkers played a dangerous game of chicken as part of their daily commute. Anxious and impatient people would inch precariously close to the edge of the train platform and then lean over the side to look down the tunnel. I often wondered at the idiocy. Did these people believe that leaning and looking hastened the train’s arrival?
The PA/CIS are in many stations and they foreshadow the arrival of the next train(s) in the station. I think it is helping to keep a few edgy folks away from the platform edge.
