I suggest the via rail Quebec City to Winsdor corridor route with those new SCV42 trains from siemens mobility
This route sounds great. A couple of CN diesels for freight services would be great to see on this route. I'd suggest an SD75I, ET44AC, C44-9W, ES44DC or AC, SD70M-2, or SD70I for heavy freight services and an SD40-2W or GP40-2W for local and switching services. DLCs could include a GP38-2W and C40-8/C40-8W.
