Now that spring is back I want to do some serious railfaning. There is a CN freight only track just 200 meters behind my condominium. in St. Laurent ( Montréal suburb ) The problem is that I don't know when the next train will go through that section. How can I know that ? If I call the CN, will they give me the info, or will I be treated as a potential terrorist ? Do freight trains have a regular schedule ? TIA for any suggestion.
