LIRR Rail Freight Study

LIRR Rail Freight Load and Clearance Study
Project Overview: 
The Long Island Rail Road retained McLaren to determine the feasibility of operating 286,000-pound AREMA Plate F freight traffic along the MTA-LIRR right of way in Brooklyn and Queens, and to quantify the infrastructure improvements required to facilitate that traffic. The results of this in-depth load analysis and evaluation will assist the LIRR in upgrading the ROWs to bear additional loads and, at some locations, ensure the cars will clear.
McLaren's Role: 
The Freight Study is broken into two tasks. A Plate F Clearance Study is first, where McLaren is identifying the location and extent of any near hits or hits against a predetermined clearance envelope. The second half is a structural evaluation of under-grade bridges, which involves preparation and execution of a Non-Destructive Testing program. Key to both tasks is data collection and field survey, where pertinent information was obtained and synthesized to assist in the analysis.
