Extending Puddington's comments, it would be nice if the copy writer distinguished between "Road Name" - in these cases "Baltimore and Ohio" or "Canadian Pacific" - and "Car Name" - e.g. "Lake Superior" and "Redvers" - when describing named passenger cars. In the case of freight cars, the term "Road Number" followed by a reporting mark and a car number does, in fact, correctly identify the car.
