Method for controlling the level of tractive efforts in a train having a first locomotive at a head end of the train, constituting a lead locomotive, and a second locomotive positioned in the train behind the lead locomotive, constituting a remote locomotive, with the remote locomotive being configured to selectively operate in either of two modes of operation, such as a first mode in which the locomotive operates at a full tractive effort level of operation and a second mode in which the locomotive operates in a partial tractive effort level of operation producing a tractive effort which is less than the full tractive effort of the locomotive. The method allows selecting (e.g., at the lead locomotive) one of the two modes of operation for producing a level of tractive effort appropriate for conditions as the train moves along a length of track. The method further allows transmitting a signal indicative of the selected mode of operation from the lead locomotive to the remote locomotive. The signal is received at the remote locomotive. The tractive effort generated at the remote locomotive is controlled so as not to exceed the selected level.

System and method for selectively limiting tractive effort to facilitate train control

A method for limiting smoke and fire upon loading a diesel engine having a power piston with a variable piston gap for controlling fueling of the engine, includes sensing the piston gap value on a cyclical basis, computing the piston gap velocity, comparing the computed piston gap velocity with a preset piston gap velocity range, and adjusting engine horsepower output upon the computation of an abnormal piston gap velocity reading. Thus, engine overfueling during loading is prevented.
