I should have added ...  :)

... That a 'Solid State Relay' would be ideal, as opposed to the old 'clunky' mechanical types.  :shocked:



These are available for a $1 Buck a bag on eBay of course ...  :thumb:

... So no great expense for specialised & difficult to get parts.  :bg: 



It is a simple circuit & could be made in a VERY compact package if needed.  :dt:



The 'Schottky Diode' however, with it's absolutely MINIMAL 'Forward Voltage Drop' ...

... is still the simplest option, for trains powered on 7.4 or 11.1 or 12 Volts etc.  :)



Some of the 'Shottky Diodes' available today, if you look, drop only a TINY fraction of a Volt ...

... high current is 'the norm' in terms of what is available, using one rated at 3x your battery Voltage is sensible.  :cool:
