CIRCULAR NOTICE NO. 84

TO: TRAIN & ENGINE EMPLOYEES NOVEMBER 1, 2007

Safety Rule 1710(e) - Application in Yard Switching Operation

Be governed by the following interpretation of Rule 1710(e) from the S7A Safety Rules for all Train & Engine Employees:

"3 Step" protection required before fouling by yard crew members in Rule 1710(e) may be requested using "Short Radio Identification" outlined in NORAC Rule 710.

Example:

Conductor: "9218, stop and 3 step requested, over."

Engineer: "Roger, 9218, stopped and 3 step applied, out."

The engineer must provide "3 Step" protection before acknowledgment is transmitted. Safety Rule 1710(e) does not require a separate radio request for the three actions required by "3 Step" protection, but positive identification using engine number and acknowledgment by the engineer are both required.
