Vignelli-inspired map (designer unknown) of the Metro-North and Long Island Rail Roads. On display until March 15th at the New York Transit Museum’s exhibit Grand By Design, on the centennial of Grand Central Terminal.

Designer unknown? The amazing book “Helvetica and the New York City Subway” attributes this map to one Joan Charysyn, saying she designed it freelance in between stints at Vignelli Associates and Unimark. It’s my understanding that the map was designed to be part of a three-map system (commuter rail, subway, and locality map) that was meant to be displayed at every station. However, the scheme (much to Massimo Vignelli’s constant disgust) never really eventuated.

To my mind, this map isn’t quite as successful as Vignelli’s subway map, mainly because the Long Island RR is one uniform blue throughout, meaning the map provides very little in the way of routing information. This is probably fine for regular commuters, who know which train they need to catch, but isn’t so great for non-regular users of the system. It’s still a fine example of early 1970s transit map design, and is obviously the inspiration for this modern map (Jan 2013, 4.5 stars) of the Metro-North lines that I’ve featured previously.
