I dock "myself" every evening to charge a battery in my lower back for a spinal stim implant. Now if I held an engine in my arms at the same time do you think I could kill two birds with one stone ? Lol
I made it train related - just showing the technology is here! And the distance is probably 1/4 to 1/2 inch so there could be a " park the engine in the new charging facility" on the layout. Time for a new accessory !! JP
