The location of each station is right below the city and departure/arrival time in the search results.
In your search, you can click “Map" to see it on a map and to see the full street address.
From there, you also have the option to enter your final destination (such as airport, hotel) and get directions from the station to your travel destination directly on Google Maps.
You can also expand the trip itinerary/details icon for more information, especially when booking multiple-carrier trips which may require a self transfer between stations.
If you have already purchased your ticket, please refer to your confirmation email from the carrier for the station address.
