I just bought my first non-toy loco, an Atlas Dash 8-40BW. It comes with a built-in DCC decoder. My first question is how do I pop the top on this loco so that I can get access to the decoder? It has some delicate detailing so I don't want to break anything trying to get it open. My second question is why does it come with an alternate set of couplers? Why would I want to use one set of couplers versus the other set?
