What is a Dash 2 electrical?
Let me start from the beginning: First, GM “regular” engines, such as GP30’s, SD40’s, and GP40’s. Then, in the early ’60ies, with the advent of transistors and the such, GM decided, “hey, me can make things work better if we put these in.” And so, the Dash 2 series was born, and for a while, both “normal” and Dash 2 models were built simultaneously. Then, around 1970, GM decided that they didn’t need two models of what were basically the same engine, and so, all engines built after then were Dash 2 models. What Dash 2 really means is that these transistors control all engine systems (braking, accelerating, wheelslip control, etc.). Recently, though, GM has dropped the Dash 2 designation, and has added microprocessor control to all of the engine systems, starting with the most recently built SD60’s and GP60’s. All of GO Transit’s F59PH’s feature microprocessor controlled systems.
