ABTH 101.1


Answer: - When a locomotive is dead - When a locomotive is isolated - When any locomotive traction motors are cut out
Feedback:
When a locomotive is isolated, dead, or a traction motor is cut out and that locomotive experiences a locked axle, a wheel slip may not be indicated on the lead locomotive. Frequently perform visual checks to ensure wheels are not sliding.
