MTA Long Island Bus will provide bus and van service in place of four Long Island Rail Road trains at three Port Washington Branch stations in the early morning of Saturday, September 25, in order to allow overnight track inspections. LIRR customers will be able to transfer between trains and buses/vans at the Great Neck Station, and should allow up to 30 minutes of additional travel time in either direction.

These service changes are required to accommodate ultrasonic track inspections conducted by the Sperry Rail Car. The necessary track inspections are being scheduled during the overnight hours so as to impact as few customers as possible.

The Sperry Rail Car, a bright yellow vehicle fitted with ultrasonic and induction test equipment, is designed to detect internal rail defects not readily visible to the human eye. Defects that are found will be corrected immediately by a crew of LIRR track maintenance personnel. The Sperry Rail Car is used twice a year to inspect approximately 500 miles of LIRR track.
