Ever since the Metropolitan Transportation Authority installed new tracks on the elevated portion of the D train line in Bensonhurst, neighbors have been complaining of loud grinding noises and a constant rumbling sound that has hurt businesses and allegedly caused hearing loss. "I've been here 30 years. It used to be noisy, but livable. Now, it's killing me," said Hilna Motors owner Louis Gellman, whose auto repair shop is beneath the D train at 86th St. and Stillwell Ave. "I can't even talk to people outside. I have to bring my customers into my office."

The MTA told the Daily News that the louder-than-usual noise was caused by recent track repairs, which forced the agency to stop greasing the rails. After receiving several noise complaints, the agency says it has lubricated the tracks and "greatly reduced the noise level." The MTA says the tracks will also get quieter as they become worn in. People who live and work nearby disagree. "It's noisy as hell," said KEM Auto Center owner Steve Novak. "Customers say 'Wow, how do you deal with this.'"
