    train departure board starting point

Tips:

• The MBTA shows information for subway, busses, etc in addition to trains (use filter[route_type] with value of 2 to show only trains)
• Data from requests can be accessed just by asking for it - adding include with value trip,schedule would also return trip and schedule objects without creating additional requests
