The couplers and knuckles of a train can only stand do much wieght or pull on them. On a steep grade that limit can easily be exceeded. So helpers are placed in/on the train to add oomph without increasing the strain on the couplers. <br /> <br />On passenger trains the problem wasn't so much the weight of the train, it was more the speed. So drawbar strength wasn't the issue. On a passenger train if you put the engines on the headend there is no way that during an accident the cars can be crushede between the two engines. The passengers really hate that. <br /> <br />Dave H.
