Someday, way out in the foggy future, lies the promise of commuter light rail service through the city and on to Fort Worth and Dallas, but no details. That may be precisely the wrong way to go about this. It helps focus and build demand for bus service and helps fill the buses. It may make sense to start with rail and build bus service as needed.

And like crossroads of old, its stations are huge magnets for high-end commercial and residential development. Moreover, a rail system is growing piecemeal in the Metroplex, and Arlington should not be isolated from it. Additionally, rail is preferred option of those who would use transit.
