Ninth Avenue El derailment at 53rd Street. September 11, 1905.

At a few minutes after 7 a.m., a downtown-bound train on the Ninth Avenue El plunged from the tracks at the corner of 53rd Street, ultimately killing 13 and injuring 48, in what was then the worst subway accident in city history.

The wreck occurred at the point where downtown-bound Ninth and Sixth Avenue tracks diverged, with Sixth Avenue trains making a 90 degree turn East along 53rd Street. Ordinarily, the approaching downtown train would display a placard indicating to the towerman whether to activate the switch for the curve. In this case a miscommunication between the motorman and the towerman (who may not have been at his post) sent the train into the curve at more than three times its speed limit.

The motorman braked, but was unable to prevent two cars from careening over the edge of the trestle. One car slammed into the ground while the other came to rest partially suspended by the second floor window of no. 798 Ninth Avenue. The New York Times described the scene:

“The third car of the train, hurled forward by the weight of those behind it, was shoved over the elevated structure and its forward end was forced through the window of the apartment of Mrs. James G. Crowe, who lives above the drug store. The car rocked for a moment and seemed as if about to fall into the street. Then it settled, its forward end held by the sill of the window and the fire escape, and hung suspended like a bridge across the street. The frantic passengers clambered out of the windows and along the roof into the apartments of Mrs. Crowe, and thence to the street.”
