# §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](/cfr/49/299.409.md);
  - (6) Verification of vehicle noise;
  - (7) Verification of correct vehicle suspension characteristics;
  - (8) Vehicle/track system qualification as defined in [§ 299.609](/cfr/49/299.609.md);
  - (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.**
