<[email protected]> Subject: Re: [EVDL] miniature train EV project Power the
rails with a safe 24VAC and use that to keep a constant charge onthe batteries.
That should reduce the battery seize requirement by anorder of magnitude.The
charge current is not nearly enough to power the train in real time,but the
train probably spends half its time sitting and loading, and so 8hours gives
plenty of time for operation.]My rails in my yard are 10" gauge. I initially
put bicycle pedals as handcranks on the engine. Then when it attracted kids
for miles around, Irealized I should never electrify it because the kids would
just never gohome. By having to hand crank themselves around the yard, they
tirequickly and go home.BobOn Thu, Oct 22, 2020 at 3:01 PM Glenn Brooks via EV
