The Taking of Pelham One Two Three

Blue electrocuted himself because he was cornered with no escape route. When Garber confronted him at the emergency exit, Blue realized capture was inevitable. Rather than be taken alive or face interrogation, he deliberately placed his foot on the third rail, choosing suicide over capture.

Earlier, Blue had demonstrated his ruthless determination by killing Grey when he became a liability, showing he would do anything rather than be caught.

The hijackers intended to restore power to the train and set all signals to green toward South Ferry, allowing them to exit the subway and vanish into the city. By overriding the dead man's switch, they made the train run autonomously, creating distance between themselves and pursuing police while they discarded disguises and fled through emergency exits.

Early in the negotiations, transit officials speculated that one hijacker was a former motorman who could manipulate the train's controls and route.

Grey killed Dolowicz because he approached the hijacked train with what appeared to be a Grand Central Grand Plan, possibly attempting to intervene or negotiate. This act demonstrated the hijackers' willingness to kill anyone who threatened their operation, escalating the crisis and showing they would not hesitate to use violence.

The dead man's switch is a safety mechanism that automatically stops a train if the operator becomes incapacitated. The hijackers overrode it so the train could continue moving without anyone at the controls, allowing them to exit while the runaway car carried police attention away from their actual escape route.

Garber suspected early on that one hijacker was a former motorman familiar with train systems, which explained their knowledge of how to bypass safety controls.

Blue killed Grey because Grey had become erratic and uncontrollable, posing a risk to the hijackers' escape plan. When they confronted each other at the emergency exit, Blue viewed Grey as a liability who might compromise their getaway or talk to police. Blue's military background made him willing to eliminate anyone he considered a weakness.

Green escaped through an emergency exit onto the street while the train was moving autonomously and police were focused on Blue's confrontation. As a former motorman, he knew the tunnel system and exit locations, allowing him to slip away before police could catch him. He was the only hijacker to successfully flee the scene.

Early in the hijacking, officials noted that Green sneezed frequently, a detail that would later link him to the investigation through Harold Longman's identical sneeze.

The ransom transport crashed because the police car carrying the money was traveling at high speed through Manhattan and failed to reach 28th Street in time. This forced Garber to bluff that the money was at the station entrance, leading to a risky foot delivery through the tunnel while snipers and hijackers exchanged fire.

Garber deduced that the surviving hijacker was a recently discharged motorman because the three dead hijackers were confirmed not to have been motormen. This narrowed the suspect pool to former transit employees. A checklist led them to Harold Longman, who attempted to bluff but was caught when he sneezed, the same sneeze pattern Green had exhibited during the hijacking.

The running 'Gesundheit' motif throughout the negotiations was not just comic relief but a crucial identifying detail that linked Green to Longman.

Garber says 'Gesundheit' as a natural, human response during the tense negotiations, but it becomes a crucial clue. The repeated exchanges humanize the standoff and create an identifying pattern. At the end, when Longman sneezes, Garber's automatic 'Gesundheit' confirms his suspicion that Longman is the fourth hijacker.

Green's persistent sneezing throughout the hijacking was a distinctive behavioral marker that police used to eventually identify the escaped hijacker.

Brown was killed by a police sniper during the ransom exchange at the tunnel. When officers approached with the money, a sniper shot Brown as he stood guard for the hijackers. The hijackers responded by opening fire on the officers, and Brown fell in the crossfire while the train roared along.

Blue ordered the signals set to green all the way to South Ferry because it was the southernmost station on the line, offering the hijackers the longest tunnel stretch to escape. However, Green deliberately moved the train farther south than planned to create more distance from police, which ultimately led the runaway car into the South Ferry loop where automatic safeties brought it to a halt.

The hijackers needed a former motorman because executing the escape required expert knowledge of the subway system's controls, signals, and routes. Only someone with motorman experience could override the dead man's switch, manipulate signals, and know the location of emergency exits. This technical expertise was essential to their plan of using the train itself as a distraction while they fled.
