In summer 2019, we attended a hearing of the Bureau d'audiences publiques sur l'environnement, BAPE. We requested access to content information from Central Maine & Quebec Railway, but unfortunately it was confidential.
However, thanks to the placards, you can easily see the numbers and get a good idea of what's going through. I installed a surveillance camera in the trees and I film every train that goes by. That way, I can find out what products are being transported. Anyone with a cellphone or any public authority can easily know what is currently passing by despite the industry's well-kept secrecy.
