New York City Transit specific situation - introduction

Some New York Subway terminology:

• A line is a physical train structure and set of tracks. NYC Subways has 34 lines.

• A service is an operating route. Services are designated by numbers for the A Division (e.g. ) and by letters (e.g. ) for the B Division.

A given service will run over different lines. For instance, an train will uses 5 lines: Astoria, Queens Boulevard, Broadway, Fourth Avenue and Sea Beach.

Some lines are identified as trunk lines and gives their color to the services that uses them (in Manhattan). For instances and services all go through the Sixth Avenue truck line that is bright orange.

New York City Transit specific situation

All the lines are interconnected. Within a division, the trains can be, and frequently, are reassigned from one line to another. Furthermore, NYCT maintains the rolling stock on a small number of large shops. For instance, on the B Division, NYCT has three shops.

NYCT needs a system-wide homogenous train control system

How do you procure a system that improves throughput, safety, and state of good repair and that will take decades to deploy?

NYCT has opted for CBTC and for the development of a standard with multiple qualified vendors called I2S: Interoperability Interface Specifications

I2S lessons learned and main Changes

1. Radio and transponders are handled as subsystems Carborne/Wayside2. No air gap I2S interface3. Proprietary radio for interference resilience and long term procurement4. Addition of the ATS5. Addition of the SSI interface for the Auxiliary Wayside System6. Miscellaneous functional improvements7. Integrated Test Facility (ITF) and a Test Track for future qualification / deployment8. Database and survey tool9. Safety certification10.Rolling Stock Interface (ICD)

ATS Strategy for Division B (1 of 2)

QBL ATS will be deployed and expanded over the B Division with three incremental levels of functionalities through ATS database modifications.

ATS Strategy for Division B (2 of 2)

Initially, for the Queens Boulevard Line Project:

• Level A: end to end for E, F, M, N, Q and R services

• Level B: part of E, F, M, N, Q and R services

• Level C: only for the Queens Boulevard Line.

These coverages will be expanded under subsequent projects.

Conclusion

Over the last 20 years NYCT has developed a comprehensive strategy for its CBTC program based on multi –supplier interoperability.

Queens Boulevard Line is the next critical step.
