WOODBURY - A former Long Island Rail Road worker is admitting to his part in the massive billion-dollar disability scam.

Gergory Bianchini, a former locomotive engineer, is the 17th retiree to admit a role in the scheme.

Bianchini worked for the LIRR for 29 years before retiring in 2003.

Bianchini will now give up more than $330,000 in illegally obtained benefits.

Since last year, more than two dozen retirees have been charged in the scam.
