Answer: If brakes apply the actuation and independent application/release hoses may be crossed.
Feedback:
If the actuation and independent application/release lines are crossed, charging occurs in the independent application/release line with 120-140 psi of pressure. This will cause the independent brakes on the trailing locomotives to apply. If actuating results in brakes applying on trailing locomotives or a sudden change in slack is noted, stop and check MU hose connections.
