Well, I do not know for sure and I have not been in the area too much
recently, but I worked the Mohawk for the last ten years before I retired
and it was always considered a night division for freight trains. Most of
the van trains would leave in the AM out of Selkirk and most of the freight
trains would leave in the PM or very early AM out of Selkirk.
Traffic patterns sometimes change and that might be what is happening
It was an interesting line to work and I am sure that it is an interesting line
to watch today as well.
PS In my day out of Buffalo, freights early in the AM and into the daylight
part of the morning, then vans and more vans during mid-day and into
the afternoon. One or two more freights possible in the evening.
