LIRR says the eight violations occurred near Penn Station, Jamaica and a rail yard in Rockaway. All the trains were moving at less than 15 mph. Four were carrying passengers.
The agency must replace the entire train crew and inspect track and signal systems when violations occur.
The train crew accused of the violations faced internal disciplinary action and sanctions by the Federal Railroad Administration.
The union representing the LIRR's 400 engineers declined to comment.
