Various, Harper's Round Table, December 24…
“ It is early in the morning and late in the afternoon that there is the greatest activity in the yards of the New York Central Railroad. Between seven and nine in the morning so many trains come in that frequently the switching necessary to give them clear ways in and out has meant the moving of 1400 levers in the tower-house. Hardly an engine, as it passes Forty-ninth Street, dragging its train on its way in, but darts away from the cars to a siding, leaving the train to roll in by itself, controlled by the trainmen at the brakes. ”
