a consist, Locomotive consist is rearranged,
Changing op- erating ends.
2. Is a *Locomotive Air Brake No, not in RCL operations.
Test needed during RCL
operations*, if the same
locomotive is restored to
lead as it was at the
beginning of the shift?
Air Flow Method and Brake Pipe Leakage Method
3. What are the two types of
*Brake Pipe Leakage Tests*?
4. What is required in order Controlling

Leakage Test*?
Charge the brake system to at least 75 psi; *air flow
5. How does one conduct an must not exceed 60 CFM*. If air flow does exceed
*Air Flow Method Brake 60 CFM--in- spect train for leakage and retest.

exhaust stops--wait one minute, Cut-out the
automatic brake valve, and then wait an
additional minute for brake pressure to
equalize, Time the brake pipe leakage for one
minute. If leakage *does not exceed 5 psi*
then test CW. If it does, check for leaks and
