On October 12, 1912 the branch was electrified. In the 1920s the branch began to lose patronage and the LIRR sought to rid itself of the line. There was a proposal for the city-owned Independent Subway System to buy the line and incorporate it into the New York City Subway system. The deal was not successful, most likely due to the numerous grade crossings that would have been extremely costly to remove. The Interstate Commerce Commission allowed the LIRR to abandon the line in 1932.
