Destroyed trolley after an explosion near the Grand Central Terminal Powerhouse at 50th Street between Park and Lexington Avenues, December 1910.

On December 19, 1910 an explosion at the New York Central Railroad's Sub Station killed 13 people and injured dozens of others. At 8:22 A.M. the massive explosion (likely two blasts, one from a gas issue and one from the dynamite kept in the still-being completed powerhouse) rocked the area. The blast threw up brick, stones, beams, and other building materials, tossing them hundreds of feet. Windows in the area were blown out and a passing trolley felt the brunt of the force, killing at least four passengers.
