The propulsion control system of a diesel-electric locomotive includes means responsive to the rotational speed and the gross horsepower of a locomotive engine for controlling the rate at which traction load is added to the engine when more, load is called for, so that the loading rate will increase (between predetermined minimum and maximum limits) as the product of speed and horsepower increases. The loading rate is also increased in response to the ratio of combustion air to diesel fuel increasing above a predetermined no-smoke threshold.
