 Unless one has a very dirty layout area I can't imagine it being worth the 
trouble to install all this specialized equipment into all one's locos. 
Decoders are pretty cheap and fool proof these days, DCC and frog juicers have 
eliminated any block wiring concerns,  and nickle silver rail indoors in a 
normal room is mostly trouble free.
 I can see battery power being attractive to garden railroaders but I don't 
know why most indoor operators would be interested in it? ........DaveBranum
