The MBTA Rapid Transit Station layers represents the station stops on the five subway, streetcar/trolley and Silver Line bus lines in the Massachusetts Bay Transportation Authority's rapid transit rail network. The five 'T' lines - Blue, Green, Orange, Red and Silver - are represented with linework in the layer MBTA_ARC. Stations are contained in a point feature class named MBTA_NODE.
The layers were developed by the Central Transportation Planning Staff (CTPS), with additional editing by MassGIS based on current information from mbta.com.
It should be noted that the Silver Line actually consists of buses, not trains, but the line is included in this layer because the MBTA includes it as part of its Subway system (see http://www.mbta.com/schedules_and_maps/subway/).
The MBTA Commuter Rail lines are included in the Trains layer.
Original linework was acquired from 1:100,000 USGS Digital Line Graph transportation data, and updates and additions were made by CTPS staff. MassGIS performed further quality checking and updating of the station names and some adjustment of the features to ortho imagery. The Silver Line was added to the layer with the April 2004 update. As of the January 2006 update, all linework and points were provided by CTPS, replacing and arcs from the DLGs.
Older Arc/Info coverage versions had the points as a NODE feature class, but editing for recent versions was done using shapefiles, and the link between arcs and true nodes was lost. The name of the layer MBTA_NODE still uses "NODE" so that the MassGIS Data Viewer and OLIVER applications will continue to function properly.
