At that time, there were cab signals on the New Haven Line, but not on the Harlem Line. Engineers were required to cut in the cab signals when they passed CP 212 (old VERN Interlocking). There were two deadheads heading east in the rock cut on track four. The first train had stopped when the second train hit it from behind. The engineer of the second train, Ray Hunter, was killed.

As Capecodloco has indicated, the switch in the cab is called a "mode switch", not a cut-out, because it selects the mode of operation. If the mode switch is in the reverse position for operation in uncoded territory (manual block or CTC with no cabs) it will cause a penalty brake application if a cab signal code is detected.
The pictures in Trains magazine from the time show the horrible remains of two trains telescoped together in the rock cut.
What happens if the cab signal switch was just cut in all the time? Why did it have to be switched on and off?
