You misunderstood me. For one, I simply assumed that locomotives have big engines for a reason and thus the number can’t be calculated for the entire train. For two, when I mentioned the capacity of cars, I meant maximum passenger capacity. I said that because at maximum passenger capacity, cars become a reasonable means of transportation whereas normally, they are ridiculously inefficient.
