CMQ omments: Reception of the HOT/EOT signal usually indicates that there is a train in the vicinity of the Onawa Trestle. A short beep at the end of a transmission indicates it is a transmission on the repeater.

CP is currently (June 2020) dispatching from their Iowa backup dispatching facility instead of the normal Minniapolis, Minnesota facility due to the civil unrest there. Track warrents issued by the CP dispatcher to CMQ are numbered sequentially starting at 01 and are typically a maximum of 2 digits (18, 19, 20)
