These maps below are for my fellow Cambridge-Somerville residents who use the Red Line every day to travel south. It tells you exactly which train door to go through in order to reach the exit you’re looking for at your destination.
Please let me know if something isn’t correct. (mchenstudio @ gmail.com) Also feel free to email me if you know which doors to use for destinations outbound or for any stations south of South Station.
If you re-post this, make sure you link back to this page.
How to use the map:
The maps to South Station show the train as it would appear when you’re standing at the inbound platform facing the train. The train is traveling south to the right if you’re at Alewife, Harvard, Central and Kendall, and it’s traveling south to the left if you’re at Davis and Porter.
The stations are in geographical (chronological?) order.
Everything else should be self-explanatory.
Alewife Inbound (hi-res link)
Davis Inbound (hi-res link)
Outbound to Alewife (hi-res link) – not reflective of which side of the station you’re standing on. Left: front of train.
Update 1: The inbound platform at Harvard is to the right of the station. (Thanks mtrem225 on reddit.)
Update 2: The exit off by itself at Park St. is an emergency exit. (Thanks harbinger via email.)
Update 3: The Pearl St. exit at Central and the Main St. exit at Kendall are at the 2nd door of the front car. (Thanks DaWolf85 on reddit.)
Update 4: Thanks to Ross Benson for sending over outbound info.
