Begun in 1909 as part of an effort by the New York, New Haven and Hartford Railroad, during the building of the new railyard in Cedar Hill rail men wanted to strike, but were able to get the extra pay to work all the hours the construction of the yard would require. Cedar Hill Yards had 14 yards of the 25 that were in New Haven at the time. The railyard could hold over 15,000 cars at a time. The trolleys were stored in what is now the Connecticut Transit Bus Terminal. The building still stands virtually unchanged from when it housed trolleys. Even though the railyards are now all but empty, they still are a dominant part of the central part of the Cedar Hill District.
