Answer: Close the angle cock between the last car and the ETD
Feedback:
If you're on a smaller train such as a Local, an air turbine ETD may bleed down your air by more than 5 psi before the test is complete. If that happens, you must close the angle cock between the ETD and last car to get an accurate test.
