Pre-Departure Brake Tests

a. Locomotive Brake Setup for Multiple Unit (MU) Operation. These

setup checklists shall be conducted or confirmed when the engineer first accepts the

locomotive from the engine house or the previous shift.

Lead Locomotive Setup:

Insert brake valve handle in independent brake valve and move to full "applied"

position, if not already in this position.

Depress handle of MU-2A valve and move to "lead" position, if not already in this

position.

Apply automatic brake valve handle to brake valve and move to "release"

(running) position, if not already applied or in this position.

Check feed valve and verify that it is set for 80 psi, reset if necessary.

Trailing Locomotive Setup:

Check to see if the locomotive is already set up for the trailing position. If not,

proceed with this checklist.

Fully apply independent brake.

With automatic brake valve, make a full "service" brake pipe reduction.

Depress handle of off pilot valve and move to "out" position.

Place automatic brake valve handle in "handle-off" position and remove handle.

Depress handle of MU-2A valve and move to "Trail 26" position.

Move independent brake valve handle to "release" position and remove handle.

All locomotives in consist:

Angle cocks are in proper position between locomotive units.

MU hoses and cables are properly coupled between units.

Brake valve out cocks are in the "out" position on all units except the controlling

unit.
