East Amherst is centered in an area originally known as "Transit Station," a name that has its origins in the railroad station of the New York Central “Peanut Line” that crossed Transit Road just north of Muegel Road. As its farmlands were developed into residential subdivisions, "East Amherst" began to emerge as the most frequently used name for the area.
