I have a few Early PS2 Engines that have the Older 8.4 volt batteries and I am guessing they also have the older five-volt boards.

 

My question is I have a few sidings that are set aside for engines to sit on, charge batteries, and run in neutral for some smoke and ambient sound. The sidings have ten volt constant power supplied to them with on and off Single poll switches.

 

Will the engine batteries charge at ten volts?

 

Can I lock the engines in neutral in conventional mode so that small children operating the layout cant inadvertently turn the switches on and off sending the engines onto the mains or into the end of track bumpers. I am hoping to lock them so they won’t start /move the next time I power up the layout also.

 

Any help with any of the questions above would be great.

 

Thank you in advance for your time.

I don't know for sure that 10V will work, it is close.  I would probably pick 12V-13V to account for the Voltage drop through the board components prior to reaching the battery.

 

Yes they can be locked in neutral conventionally.  Instructions tell you how via a combination of bell and whistle buttons.

 

The better choice is using MTHs plug in charger and periodically charging each engine.  It can charge 5V and 3V systems.

 

Leaving an engine on the track routinely operating is racking up operating hours on the electronics.   G
