No update needed, this is talking about a leakage test not a train check

Answer: Stopped; Release or Minimum Reduction

Feedback:
The Air Flow method is the preferred method to use when conducting a brake pipe leakage test. If it is necessary to use the Brake Pipe Leakage Method, the acceptable leakage amount is under 5 psi. The leakage test does not have to be performed each time the train stops. That requirement falls under ABTH 105.5 Train Check.
