Yes, my preference would be for them not to operate in the area at all. How do you monitor and regulate that? That's just adding another layer of supervision and monitoring. Somebody has to do the job, collect the data, provide the reports. To me, that seems very inefficient. Why not just say they can't operate in this area in the evening, and if they want to shunt, they go to another location?
Every municipality has noise bylaws. For example, in New Westminster, it's ninety decibels during the day and sixty decibels at night. Those are hard enough to enforce for the municipality. It wouldn't be any easier to deal with the railways on those.
