aaaah! Kevin, you are now entering the mysterious and confusing world of prototypicalism, succinctly put in Chet's question, "For what railroad?" As you have discovered by pictures, and the reason for Chet's question, it can be different from railroad to railroad. Note also that both locos have ditch lights, but the yellow "Warbonnet" is above the anticlimber and the CP's are below.
So.... the follow up question is, "what railroad are you modelling?" if you are modelling a prototypical (real) one, or a fantasy one (freelance).
