text: In countries where buffers-and-chain couplers are used, bank engines often cannot be added to the front of the train due to the limited strength of the couplers; In the case of standard UIC couplers and a maximum grade of 28‰ (which is common e.g. for lines through the Alps), the limit is a train weight of 1400 tons; if a train is heavier, bank engines have to be added in the middle or to the end of the train in order not to exceed the maximum load for any coupler.
