Section 299.607 - Pre-revenue service system integration testing(a) Prior to commencing revenue operations, the railroad shall conduct tests of the trainsets throughout the system to-(1) Verify mechanical positioning of the overhead catenary system; and(2) Verify performance of the trainset, track, and signal and trainset control systems.(b) The railroad shall demonstrate safe operation of the system during normal and degraded-mode operating conditions. At a minimum, the following operation tests shall be performed: (1) Slow-speed operation of a trainset;(2) Verification of correct overhead catenary and pantograph interaction;(3) Verification of trainset clearance at structures and passenger platforms;(4) Incremental increase of trainset speed;(5) Performance tests on trainsets to verify braking rates in accordance with § 299.409 ;(6) Verification of vehicle noise;(7) Verification of correct vehicle suspension characteristics;(8) Vehicle/track system qualification as defined in § 299.609 ;(9) Load tests with vehicles to verify relay settings and signal and communication system immunization;(10) Monitoring of utility supply circuits and telephone circuits to ensure the adequacy of power supplies, and to verify that transient-related disturbances are within acceptable limits;(11) Verification of vehicle detection due to shunting of signal system circuits;(12) Verification of safe operation of the signal and trainset control system as required by subpart B of this part;(13) Tests of trainset radio reception during system-wide vehicle operation; and(14) Verification of electromagnetic interference/electromagnetic compatibility between various subsystems.
