By now the phrase "social distancing" has got to be pretty much worn out so I apologize for bringing it up once again, but that is what's going on in this picture. "CN 595 is a full crew outpost road switcher, meaning engineer, conductor and brakeman. To (provide adequate) social distance, they need the brakeman to be in another unit, or to have a company vehicle to travel by road to where the train’s next stop is. The company won’t give vehicles to crew members, so the union demanded a second unit to sit in". Quoted info from a CN employee who's name I will withhold for the sake of privacy.
