Or 4%.

One freight train, a CN freight train today that operates with two or maybe three locomotives, carries the same amount of cargo as roughly 200 tractor trailers. That's why you see a number so low as 4%, because if you took one of those trains out that travels from Halifax to Vancouver, you would have to run 200 trucks for the same distance. That's the benefit of rail: because you have steel on steel, you have almost no friction other than wind, and you increase your efficiencies dramatically.
