The Purple Line, a transit project that would link New Carrollton and Bethesda, is an idea that has been bandied about for years. As the Post noted last week, shifting growth patterns and economic trends make the need for just this kind of inter-burb transit even more urgent.

For a while, Maryland seemed to have pushed the Purple Line off the table with the decision to support the multi-billion dollar Intercounty Connector instead. However, state transportation officials have recently been working to reassure us that they still intend to build the much-discussed line. This, however, has led to questions about exactly what Maryland has in mind for the Purple Line.
