This standard provides procedures for inspecting, testing, and maintaining rail transit closed circuit television (CCTV) systems. This standard intends to meet the following objectives:-To ensure special life/safety equipment is operational and reliable-To help rail transit systems incorporate safety considerations during the inspection and maintenance process-To identify inspection criteria and maintenance standards that provide a high level of passenger and personnel safety The application of any standards, practices, or guidelines contained herein is voluntary. In some cases, federal and/or state regulations govern portions of how a rail transit system operates. In such cases, the government regulations override any conflicting practices this document requires or recommends.

This paper includes the findings and comparison of the performance-based seismic assessment of the existing Grand Avenue Viaduct in St. Louis Missouri versus the conventional methods currently practiced in the state of Missouri. The central portion of the existing bridge is comprised of seven (7) spans with a total length of 676’-8”, consisting of a reinforced concrete deck slab on built-up steel girders supported by multi-column reinforced concrete bents founded on a combination of pile-foundations as well as spread footings. The existing structure reflects typical design techniques of 1950’s with the main focus on vertical load resistance. This study includes the seismic assessment of the existing bridge, evaluation of its performance as a critical structure prone to significant seismic risk due to close proximity to New Madrid and Wabash Valley seismic zones while serving a vital link between North and South Grand Boulevard, and final recommendations to the City of St. Louis for ...
