Abstract: This datalayer comprises the four subway and streetcar LINES in the Massachusetts Bay Transportation Authority’s rapid transit rail network. The four ‘T’ lines - Blue, Green, Orange, and Red - are represented with linework. The data is maintained in ESRI coverage format and was developed by the Central Transportation Planning Staff (CTPS) and is stored as a single statewide layer called MBTA.

Abstract:

This datalayer comprises the four subway and streetcar LINES in the Massachusetts Bay Transportation Authority’s rapid transit rail network. The four ‘T’ lines - Blue, Green, Orange, and Red - are represented with linework.  The data is maintained in ESRI coverage format and  was developed by the Central Transportation Planning Staff (CTPS) and is stored as a single statewide layer called MBTA.

Purpose:

This data set is the location of rapid transit lines in the MBTA light rail system
