Thank you, Mr. Julian.
My response is that I think it would be a bit of both. I think during the daytime hours there could be a different standard from what there is in the evening hours, as far as rail operations go. I would draw a comparison to the Lower Mainland here, where there are a number of trucking companies. My impression is that they typically operate during daylight hours only, so they effectively close down at night.
I appreciate that the railway companies run on a 24-hour clock, but if a marshalling yard is located within close proximity to residential neighbourhoods, I believe there should be some acoustic restrictions placed on the operation of that yard in the evening hours.
