Washington, D.C.'s efforts to mimic Tucson, Ariz., and Atlanta by opening a new streetcar line during 2014 fell short at New Year's Day approached.
The city's initial H Street streetcar line, running along its namesake street in the city's Northeast quadrant east from Union Station, was delayed repeatedly throughout 2014 by testing and by safety concerns, thwarting the ambitions of outgoing Mayor Vincent Gray, an ardent streetcar proponent, to inaugurate the service before stepping down on New Year's Day.

The 2.4-mile line has received safety clearances from the Federal Transit Administration, but must still be certified by the D.C. Fire Department as safe. As the year waned, published reports of municipal squabbles over safety issues cast a 2014 debut into even more doubt.
An opening date for 2015 had yet to be officially announed as of Dec. 31, 2014.
