They looked like pictures of what one sees of miners in underground tunnels. 4-5 men, in hardhats and florescent vests with stripes walking far away among the train track of the subway. These tracks are three levels down and so increased the feeling of watching miners. In order to communicate they sent light flashes from their hand held flashlights. When the trains passed, they flattened themselves against the walls. At one arrival, the train slowed like I had never seen it do previously, and when that didn’t satisfy the conductor, he honked a horn. The first time I had heard a subway train honk.
