[PRCo] Re: Power Off

[Fred Schneider]

It indicates an section insulator between two sections of wire.    
Notice the insulators hanging to the left of the orange power-off  
sign.   The wire section near the camera was fed from a different  
substation that the section feeding the section of wire in the distance.

The motorman was required to coast through the insulator to prevent  
damage to the insulator.   Phrased differently, he was to turn POWER  
OFF when he went through the insulator.

Of course there is often a static load.   Lights will be on at  
night.   Air compressors might be running.   You cannot prevent all  
load.   But hopefully you can prevent maximum load and an idiot  
motorman will not notch up the car under the insulator and weld the  
the two ends together.

Understood????
