Exploring D.C. Metro Delay Data in Tableau


Exploring D.C. Metro Delay Data in Tableau

Washington, D.C.’s Metrorail, opened in 1976, covers 110 miles of subway track, 6 metro lines and 91 stations. System upgrades have been long overdue, with considerable malfunctions and delays surfacing at greater frequencies over the past few years. From a train fire that killed a passenger to operators abandoning their trains once their shifts are over, the Metro has a considerable amount of work to do in improving the safety, infrastructure, and performance of the rail system. 

As of May 2016, Metro launched its SafeTrack program – a $5 billion program intended to perform the upgrades that are so badly needed. I decided to explore the types and frequencies of delays on the Metro over the past few years and visualized the data in Tableau. Enjoy!
