49 CFR §299.607

1. (a)Prior to commencing revenue operations, the railroad shall conduct tests of the trainsets throughout the system to—
   1. (1)Verify mechanical positioning of the overhead catenary system; and
   2. (2)Verify performance of the trainset, track, and signal and trainset control systems.
2. (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. (1)Slow-speed operation of a trainset;
   2. (2)Verification of correct overhead catenary and pantograph interaction;
   3. (3)Verification of trainset clearance at structures and passenger platforms;
   4. (4)Incremental increase of trainset speed;
   5. (5)Performance tests on trainsets to verify braking rates in accordance with § 299.409;
   6. (6)Verification of vehicle noise;
   7. (7)Verification of correct vehicle suspension characteristics;
   8. (8)Vehicle/track system qualification as defined in § 299.609;
   9. (9)Load tests with vehicles to verify relay settings and signal and communication system immunization;
   10. (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. (11)Verification of vehicle detection due to shunting of signal system circuits;
   12. (12)Verification of safe operation of the signal and trainset control system as required by subpart B of this part;
   13. (13)Tests of trainset radio reception during system-wide vehicle operation; and
   14. (14)Verification of electromagnetic interference/electromagnetic compatibility between various subsystems.
