Si une locomotive peut tirer, admettons, 200 wagons et qu'elle a le choix de tirer, pour faire simple, 200 wagons de céréales ou 200 wagons-citernes de pétrole?
If a locomotive can pull, say, 200 cars and it has a choice of pulling, for the sake of simplicity, 200 grain cars or 200 oil tankers, and it gets more money for pulling oil, would the cap in that case be having an adverse effect on cars being made available for rail shipments?
