Short video of my old Lionel Large Scale PRR E6s Atlantic, now converted to onboard battery power. Engine has a 7 cell, 8.4 volt, 5000mah, Nimh RC car battery mounted in the boiler. I also added 2 more zip ties to the single one that Lionel mounted the motor with, under load the motor can "squirm" and strip the axle gears. Adding a couple more helps prevent this. Putting the battery in the boiler instead of the tender adds needed weight, but not to much as there are no true bearings in the chassis. An on/off toggle is in the boiler backhead and a charging port is under the firebox. The smoke unit was also removed, not realistic and they eat battery power. This one had its dead railsounds gutted by a previous owner. I am searching for a pair of the boiler or tender marker/class lights to add the second pair that PRR used on the pilot deck on the pre-modernization engines. The engine had been running non stop for just over 2 hours when I shot the video. Mike the Aspie
