A federal judge has ruled that a former Amtrak worker can move ahead with a suit claiming he was fired based on mental health issues.

U.S. District Judge Peter Sheridan of the District of New Jersey on Sept. 18 denied Amtrak's motion for summary judgment, finding sufficient factual disputes to allow that lawsuit filed by plaintiff David Rollins to move forward.

According to the decision, Amtrak fired Rollins, a 23-year veteran of the railroad, on Aug. 4, 2015. Rollins, a resident of the Bronx, had for 10 years been a supervisor and was in charge of a night crew working on track maintenance. He worked in an Amtrak facility in North Brunswick.
