When the subway first opened in 1904, maps were simple diagrams that depicted individual subway companies, such as the Interborough Rapid Transit Company (IRT), the Brooklyn-Manhattan Transit Company (BMT), and the city-owned Independent Subway System (IND).

The redesigned map includes brighter colors, bold, straight lines, and a white background, all aimed at maximizing contrast and legibility.

NEW YORK (WABC) -- The MTA unveiled the first new subway map for New York City in more than 45 years on Wednesday morning. This map has significant differences. No longer a spaghetti diagram, this map emphasizes the lines over maintaining geographical accuracy. It is easier to read with its bold colors.
