Re: Lobato Design Assumption

No idea.... I'm the wrong type of "engineer". Steam locomotives are balanced to reduce "pounding" to a certain point. At a high enough speed they will get out of balance. Another pounding effect is from piston thrust which will tend to make a locomotive "hunt" from side to side. From talking to old timers a K36 could not be run over 35mph because the piston thrust made the engine begin to hunt badly. Shoving on a train changes all the lateral forces. Instead of pulling the train straight, shoving tends to make the train want to buckle up sideways. You can feel the engine on a rear helper want to crab sideways when pushing hard.
