We're looking for a scale Santa Fe dummy B unit (preferably Lionel) to mate up with a Scale AA pair of Warbonnets and most seem to have TMCC w/a backup light and electro-coupler.
What is the practicality of having these features (and associated cost) when most are used in an ABA or ABBA configuration?
I realize that occasionally, an AB or even ABB setup is used but these are certainly not 'the norm'...
By the way - anyone have a dummy B available?
