Cunning! A hauling rope can handle incredibly heavy loads. Thus the tear limit of the trains we offer is several tons of tractive force. If necessary, you can even tow cars with it. Why a train still tears is because it is loaded wrong. Train killer no. 1 is the so-called common cast iron burr. Often the brake-clutch levers are not properly deburred and the train is chafed by it. Also in the steering head itself, where e.g. the outer cover of the clutch cable is supported, a bad friction point can lurk. Here only careful control helps. All Bowden cables should always be oiled and greased before they are installed. This effectively prevents them from freezing in winter temperatures or water from entering the cable and corroding the cable. Exceptions are the extremely low-friction Teflon complete trains and the original PX-Lusso trains. These may only be oiled with acid-free oil, e.g. Hanseline sewing machine oil.
