The slight curve of the platform at Spring Street

[image error]Ever notice that the subway platform at the Spring Street 6 train station has kind of a curve?

Instead of a straight platform from end to end, it’s shaped like a slight C, so when the train cars pull in, they almost curl a bit against it.

Is it an IRT thing on the entire East Side line? In any case, it makes the station feel a little less cold and grimy—a little more bouncy.
