On fast track to prison

A retired LIRR electrician got rerouted to the slammer yesterday for taking part in the massive “gravy train” disability scam.

Gary Satin, 63, was slapped with 20 months behind bars and ordered to pay back nearly $250,000 in crooked pension benefits he pocketed by falsely claiming he couldn’t work due to chronic back pain.

His sentencing marked the first punishment of the nearly two dozen people who have pleaded guilty in the rip-off of the Railroad Retirement Board.

Satin, whose bogus ailment also scored him a handicapped parking permit, was busted after an acquaintance videotaped him installing an underground irrigation system and ratted him out.

”What he did was terribly harmful to the government and to larger society,” Manhattan federal Judge Victor Marrero said.
