I'd like to get a small GE 44 tonner type loco for my garden rr. I've seen one in mags,it might be by USA, I'm not sure. Here's the thing, I want battery powered r/c, preferably installed and rtr. Does anyone know if anyone sells them like this? Any idea on cost and whether they are available with and without sound? Regarding sound just a horn would be good, enough to keep my grand daugther entertained without having to hear the diesel engines for hours. Any leads are appreciated!
