What connections are made between multi-units which are equipped with 26L air brake equipment? |
* multi-unit jumper cable to be coupled to the adjacent connection not diagonally Air hoses on the locomotive: - main reservoir hoses - brake pipe hoses - No3 control pipe hoses - No4 independent release pipe hoses When locomotives so equipped are to run as a multi-unit, normally one flexible hose of each type is required to be connected between the locomotives. |

|
How do you test the brakes on multiple units? |
A competent worker checks if the air brake applies and releases on each trailing locomotive. |
|
|
How do you do a movement test on multiple units? |
A competent worker must check the trailing locomotives power and reverse while moving in both directions and the set back is done safely. |
|
|
How do you do a power test on multiple units? |
A competent worker will observe if the load ammeters in the trailing units are reacting correctly when the driver applies power. |
|
|
What are the CW duties during multi-unit coupling? |
- set up ato couplers to be coupled - remove dummy couplings from flexible air hoses - signal driver to move locos together - see auto couplers to properly unite - hand signal the driver to gently draw the loco forward to ensure that the couplers are locked - insert auto coupler locking pin if provided - connect adjacent flexible air hoses and fully open the corresponding air cocks - obtain multi-unit jumper cable from storage location for the driver or maintenance staff member to insert. * couple adjacently |

What connections are made between locomotives in multi-unit, when one unit equipped with No4 air brake equipment is to be connected to locomotives with 26L air brake equipment? |
The Y class loco, which is fitted with No4 air brake equipment, does not have No3 control pipe hoses or No4 independent release pipe hoses, therefore only the brake pipe and main reservoir are connected when coupled to locomotives with 26L equipment. |
