R142 train that will be transferred to the Flushing Line and equipped with CBTC
Project Description
Parsons has been tasked to develop Procurement Specifications for communications based train control (CBTC) systems for the Second Avenue Subway and Flushing Lines. These Specifications are based upon the Canarsie Line Specifications and are being updated by Parsons to incorporate New York City Transit's (NYCT’s) Interoperability Interface Specifications and line-specific requirements. A critical requirement of the Second Avenue Subway and the Flushing Line communications based train control/auxiliary wayside system (CBTC/AWS) project is to build on the experiences of the Canarsie Line pilot project, and in particular, to have the ability to procure CBTC/AWS systems for these lines that are compliant with the interoperability interface standards that have been developed by Parsons and validated under the Canarsie Line project.
The CBTC systems must integrate with the following NYCT system-wide data communications and control projects: Automatic Train Supervision (ATS), Public Address/Customer Information System (PA/CIS) and the fiber optic SONET/ATM Communications Network System (SACNS). Significant lessons learned from the Canarsie implementation, particularly the test and commissioning program, are being incorporated into the Flushing project requirements and specifications.
The primary project goals for Flushing can be summarized as follows:
- To complete the preliminary engineering for resignaling of the Second Avenue Subway line on schedule and within budget, and in concert with the overall Second Avenue project schedule.
- To complete the preliminary and final engineering for resignaling the Flushing Line on schedule and within budget, and with minimum impact to revenue service operations and in concert with other improvement and extension projects on this line.
- To successfully integrate CBTC system elements onto the different vehicles that will operate on both lines
Parsons’ scope for Flushing consists of the base agreement plus options:
- Preliminary engineering for a CBTC system for the Second Avenue subway.
- Option 1: Conduct final design and support procurement of CBTC system for Second Avenue subway.
- Option 2: Provide technical support services during construction of the CBTC system on the Second Avenue subway.
- Option 3: Provide technical support during construction of the CBTC system on the Flushing line.
Parsons is a worldwide leader in the development, design, and implementation of CBTC Systems on new start transit systems and the retrofit of CBTC on established operations replacing convention wayside based signaling and train control.
