Last October, LIRR forces temporarily relocated approximately 1,000 feet of each of the two main tracks along with LIRR communication cables and poles to an area about 60 feet north of their former location.
The National Grid work included removal of soil contaminated by a manufactured gas plant operation that had previously been located in the area. National Grid is paying for the track relocation and soil remediation work. The project is being carried out with the approval of the New York State Department of Environmental Conservation.
Train service on the LIRR West Hempstead Branch will be affected as rails are inspected by the Sperry Rail Car between Valley Stream and West Hempstead April 20. Four midday trains, two eastbound and two westbound, between 9:21 a.m. and 2 p.m. will be replaced by buses.
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 eye. Defects that are found will be corrected immediately by a crew of LIRR track maintenance workers. The Sperry Rail Car is used twice a year to inspect approximately 500 miles of LIRR track.
