A grade crossing activation failure at 02:11 had me issue an emergency stop on Sub 4, and the challenge is sequencing the calls without cluttering the air. For those just stepping into dispatch, how do you order the first 60 seconds — emergency broadcast, lock routes on the board, alert the adjacent desk, loop in PD/FD — and what’s your tactic for keeping channel 3 clear while you roll protection?
At 02:11 I hit the priority tone and fire a canned line: “Sub 4, emergency stop — grade crossing activation failure — acknowledge only if affected, keep channel 3 clear,” then I lock the routes and ping the adjacent desk on intercom while shifting the longer stuff to the desk phone so the air stays open… Having that script hot-keyed on the console saves seconds; if you’re solo on nights, I’d delay the PD/FD dial-out by a beat until the first acks and stops are.
I keep a 60-second crib in CAD: priority tone, ‘affected trains acknowledge only, channel 3 clear,’ then throw electronic blocks on the two nearest interlockings and push a blanket stop via PTC before looping PD/FD on the ops phone. If the adjacent desk’s juggling a mess, I hit them on desk chat first and only lock the immediate approaches, expanding once the first acknowledgements settle — triage, not a novel.
