Route Locking Tests Rail Transit Systems Signals & Communications This standard provides prerequisites, procedures and requirements for testing rail transit route locking. Individual rail transit systems may modify these requirements to accommodate their specific equipment and mode of operation.
Time Locking Tests Rail Transit Systems Security  Emergency Management This standard provides prerequisites, procedures and requirements for testing rail transit time locking. Individual rail transit systems may modify these requirements to accommodate their specific equipment and mode of operation.
Traffic Locking Tests Rail Transit Systems Signals & Communications Traffic locking tests verify that traffic locking will prevent traffic from changing direction on a section of track in between interlockings while that section is occupied or while a signal displays an aspect to proceed into that section. This standard provides prerequisites, procedures and requirements for testing rail transit traffic locking. Individual rail transit systems may modify these requirements to accommodate their specific equipment and mode of operation.
Visual Inspection of Wayside Signal Equipment Rail Transit System Signals & Communications This recommended practice is designed to aid rail transit systems in identifying visual defects or other potentially hazardous conditions related to wayside signal equipment through preventative periodic inspection, thereby increasing reliability and reducing the risk of hazards and failures.
