Railways

The Central Transportation Planning Staff updated and enhanced railroad linework distributed by the United States Geological Survey (USGS) as 1:100,000 Digital Line Graphs (DLGs). The original 1:100,000 DLG data were conflated to the orthophoto-derived 1:5,000 Centerline linework now used in this layer. CTPS added several attributes pertaining to type of service, MBTA Commuter Rail status, rail line ownership, and freight and passenger operation.
