The same generalstatement applies to the operation of a train made up of cars someor all of which are but partially equipped, but which together areprovided with an operative train equipment. To effect this funda-mental result practically, it has been necessary to provide for prop-erly connecting the cars, preferably independently of sequence,number and end relation, with couplings of such character that anytrain hand can effect the coupling; to provide against cross con-nections in the circuits on the different cars; to guard against ac-cidents due to failure of circuits or current or otherwise; to se-cure practical uniformity of operation in the apparatus on the dif-ferent cars and equality of work in the various motors, and to se-cure simplicity and flexibility in the relation of the parts under allthe various conditions of operation. To accomplish this, a systemhas been devised which is in par
