We have tried running SD 70ace as a consist and have found engines running at different speeds. Lead loco will run slow, second locomotive running at higher speed will be spinning wheels. We have tried from three to seven engines together. As they run some of the couplers are stretched out some jammed together. It looks as though these engines will not support a stall setting to get all to start at same time. Has any one else had this issue?

The SD70s ran , three of them together, under conventional power on a small portable layout for an entire weekend with no problems at all. We did start having problems when running in Legacy. We ran as many as seven and as few as three on Legacy, and while running an MU in Command, running slow I could see where an engine or engines in the midst of the consist would be spinning the wheels, others would be dragged along, thus my question about being able to set stall.
