The East Side Access Contract CQ033 for the Construction of the Mid-Day Storage Yard (MDSY) is a new storage yard facility for LIRR commuter railcars. The MDSY is approximately 30 acres of new railroad infrastructure, including 9 miles of track and contact rail for 24 storage tracks and two run-around tracks, over 80 switch machines, and over 1 million ft of wire and cable. One of the interesting challenges that the construction team needed to overcome included a major re-sequencing of the track construction in order to maintain rail equipment access to an existing maintenance facility in Queens on Arch Street. There was an existing track set to be demolished by the CQ033 contractor that provided access to Arch Street, but the footprint ran directly through the middle of the new 30-acre yard. Originally, all stakeholders agreed that access to the Arch Street facility would be interrupted for a partial duration of the CQ033 contract. However, due to LIRR’s purchase of a new fleet of M9 vehicles, and necessary maintenance requirements of the current fleet, this access needed to be maintained throughout the duration of the work. Therefore, there was a major re-sequencing and redesign of the installation of all underground infrastructure (including new duct banks and manholes for traction power, communications, facility power, signal power, etc.) in order to provide LIRR continuous access to the Arch Street facility. Upon installation of all underground infrastructure, all parties coordinated a short-term outage for the installation of the new permanent trackwork, including a tie into existing LIRR and Amtrak tracks, demolition of the previous track, and return to service. All parties worked together in an impressive fashion and accomplished all work in this short-term outage under the allocated schedule and budget. 12 Railway Track & Structures // June 2022
