I really appreciate transit maps that combine different modes of transit, and this map does just that – showing Metro, light rail, trams and commuter rail in a very clean, restrained manner. Coloured route lines (blue, orange and green) set the dense and important Metro network apart from the subsidiary light rail, tram and commuter rail routes, which are shown in grey and thin black lines. Zone information is displayed through a chilly looking cyan blue background. A complete absence of curves creates a very formal, stiff look to the map. One unusual feature is the way that station markers always remain horizontal or vertical, even when the route line is at 45 degrees – making the stations “slice through” such lines at a distinctive angle.

Have we been there? No.

What we like: Good information hierarchy through intelligent use of colour. Bi-lingual legend. I really like the way the Metro route lines fold over each other as they make a 90-degree turn – an unusual graphic device that works well and lends the map a unique look.

What we don’t like: Perhaps looks a little cold and sterile. The thin double black lines for commuter rail looks a little overly fussy in comparison to the clarity of the rest of the map, although I do like the way two parallel routes are represented by just three lines (the middle line being shared by the two routes).

Our rating: A very clean, solid transit map, if a little sterile. Three-and-a-half stars.
