dead rail battery

[amtrack5899]

I am new to Rail Pro.  I plan on running dead rail battery power .  I have a 3350 mah battery that I plan on installing in a USA train switcher engine.  This will have a on/off/on switch w battery plug & charging jack with 12” leads. I would also like to use a battery car with a 4 amp hour battery for longer run time. Can I use a second  on/off/on switch to bypass the battery in the engine and just use the battery car when needed?
Thank you

of course, the RailPro unit does not care, power is power.

That seems like a complicated mission.  How long do you run trains that you need that much battery?  I run a 14.8V LiIon 3.5ah in O scale and can run continuous for about 3 hours.

If my battery in the engine is dead, I park/charge the engine and run a different engine.

USA Trains is G scale, and USAT is famous for having high stall current motors.

He's thinking in a good way.
