First I shut down Lighting or accessory transformers not on the two main power strips. ( all those are on Alexa Plugs which I tell Alexa to turn off) Then I power down All engines. Next I put all transformers to Zero Volts. Next I turn off all remotes DCS and Legacy (legacy first). Next I turn off transformers. The two power strips are high dollar, grounded and have Voltage spike protection. I leave those two on. Last thing I do, which is not necessary as everything is off, is to tell Alexa to turn off train room. This catches any plugs I missed. When I walk out the power strips, Alexa and air purifier are still plugged in. And the lift gate is plugged in still, but I am thinking of moving that to an Alexa plug also.
