A Streetcar Named Desire's title operates on many levels. Firstly, it references the name of the streetcar Blanche mentions taking before the play begins. However, the title also works on a metaphorical level. Blanche's desires are what have brought her not just to New Orleans, but to her current lowly state in general. Later in the play, it is revealed that Blanche seduced a student at the high school where she taught English, causing her to lose her job and reputation.
The specific instructions Blanche receives regarding where to get off when riding the streetcar are also metaphorical:
They told me to take a streetcar named Desire, and then transfer to one called Cemeteries and ride six blocks and get off at—Elysian Fields!
A streetcar named Desire leads her to a streetcar named Cemeteries, suggesting Blanche's actions and wishes have lead her only to death. "Elysian Fields" refers to the ancient Greek afterlife, further cementing Blanche's impending death—not a literal death, but one related to her identity. Her sexual desires have caused her to lose her job. Her social desires, related to her position as one of the last members of the old southern gentility, are also leading her to existential annihilation. Unlike her sister Stella, who has married a working-class man and abandoned the fading way of life Belle Reve represented, Blanche clings to the old ways, making up stories about old-money suitors in order to make it seem as though she is still the southern belle she once was. She avoids facing the truth because of her desire to shape reality to her wishes, and this leads her to her tragic fate.
