The Characters Trapped in the Train Wreck: Who’s in Danger?

Perhaps one of the most iconic characters in the One Chicago franchise, Kelly Severide (played by Taylor Kinney) has been a key figure in Chicago Fire since its very first season. As a member of Firehouse 51, Severide has seen and experienced countless dangerous situations, but this new train accident puts him in serious peril.
In the trailer, Severide is shown rushing into the wreckage to save civilians, but things take a turn for the worse as the situation spirals out of control. In one particularly heart-stopping moment, Severide is seen being trapped under a massive chunk of train debris, with no clear way out. His fate remains unclear, but the fact that he’s one of the main characters at risk is enough to have fans on edge. Will Severide survive? Or will this accident be the turning point that changes his character forever?
2. Sylvie Brett (Chicago Fire)
Sylvie Brett (played by Kara Killmer) is another beloved character from Chicago Fire, and her role as a paramedic has made her a fan favorite. In the crossover trailer, we see Brett responding to the disaster with her usual calm and determination. She works alongside other first responders to treat the injured, but things take a dark turn when she finds herself trapped in the wreckage as well.
As the situation worsens, Brett’s future becomes uncertain. Will she be able to escape the wreckage in time to save others, or will she become another victim of the accident? Fans have been speculating whether Brett will survive the crash or if the incident will mark the end of her time at Firehouse 51. With so many key characters in danger, her fate is yet to be determined.
3. Jay Halstead (Chicago P.D.)
As one of the leading characters in Chicago P.D., Jay Halstead (played by Jesse Lee Soffer) is no stranger to high-risk situations. In the crossover, he is called in to investigate the cause of the train accident and provide assistance to his fellow officers. Halstead’s role in this crossover is pivotal, as he is caught up in the chaos of the wreckage, trying to protect the public and uncover what caused the accident.
In one gripping moment, Jay is seen trapped in a precarious position, unable to free himself as the danger continues to escalate.

Fans are eagerly waiting to see how the events unfold for him, especially since Halstead has been a fan favorite for years. Will he escape the wreckage unscathed, or is this the end of the line for the detective?
4. Dr. Will Halstead (Chicago Med)
Dr. Will Halstead (played by Nick Gehlfuss) has faced his own personal and professional challenges on Chicago Med, but the train accident will test him in ways he’s never experienced before. As a surgeon, Dr. Halstead is thrust into the medical chaos caused by the disaster. He’s forced to make quick, life-or-death decisions while trying to save the lives of the victims trapped in the wreckage.
However, as the trailer reveals, Will is also in danger, and his life could be on the line as the situation intensifies. Will he be able to continue saving lives while navigating his own peril? With the One Chicago franchise’s history of putting its characters in grave danger, fans are worried that this could be the beginning of a heartbreaking storyline for Will Halstead.
5. Stella Kidd (Chicago Fire)
Stella Kidd (played by Miranda Rae Mayo) has become a key character on Chicago Fire, known for her courage, leadership, and determination. In the crossover trailer, Kidd is seen working alongside Severide and other members of Firehouse 51 to rescue survivors from the wreckage. But as the situation worsens, she finds herself in a precarious situation, and the trailer leaves her fate hanging in the balance.
Could this be the moment that Stella Kidd’s character faces an irreversible challenge? Fans are nervous about her potential fate, as her emotional connection to the team makes her a fan favorite.
