I’m in Boston regularly for business, and find myself on the T often.  Downloaded the EmbarkBOS app.  It has a particularly good rendering of the MBTA system. I particularly like the way they capture the several commuter rail lines out of South and North Stations in varying shades of purple. 

You’ve probably seen it, but if not, here’s an image screen-capped from my phone.

Actually, I hadn’t seen this map before (having no need of a Boston map app here in Portland, OR) , so thanks to Guy for sending it along!

Guy is right: this is a very solid representation of the MBTA “T” and commuter rail services in the one map. However, there’s one glaring error in the screenshot that Guy sent: the new Assembly station on the Orange Line (opened August 2014) is not shown. Either Guy needs to update his app to a newer version, or Embark needs to add it to their map!

A couple of minor things on the Framingham/Worcester commuter rail line: it’s not immediately obvious how the line passes through Back Bay station, as the abrupt change in direction is hidden behind the Orange Line. Also, the little jog in the line at Yawkey to separate the commuter station from the Green Line is a little awkward-looking.

The map does a pretty good job at naming all the Green Line stations, although it’s always a shame to not see the Chestnut Hill/Cleveland Circle/Reservoir station triplet in close proximity to each other. As it stands, Cleveland Circle looks like it’s quite near to Riverside, which is much, much further out in real life. However, it’s a diagram, not a map – so I can’t quibble too much about these things!

I do like the addition of airport codes to the map, which add some extra information to the map without being too visually overpowering.

Our rating: A solid combined rapid transit/commuter rail map with a couple of minor quirks. Three stars.
