MMA 811, the biweekly Ste-Rosalie - Farnham local, is pulling onto the CN from the northern segment of the MMA's St-Guillaume subdivision. It will proceed onto the main and then back up to the wye connecting the CN main with the southern segment of the MMA line, and head south to the MMA's hub in Farnham. Once upon a time, this old CP branch crossed the CN on a diamond, but that has since been removed, necessitating this maneuver.
