Amperage Draw

[britannia70]

Anyone help?

        How much amperage would a standing loco on a dcc layout be expected to draw? I have 20 loco standing locos either outside a 5 lane shed or on the fiddle yard. Control is by Gaugemaster prodigy .

Do they have lights? Do they have sound? 
 

all have an effect on the potential current draw 

[britannia70]

no lights no sound.

Then next to no power when they are standing still

I have 27 locos on a layout, one with TSS sound and some with end/tail lights. With a 'few' end lights on and none moving the current draw, according to the display on my NCE PowerCab, is 0.34amps. As @WIMorrison says, "... next to no power ...".

 

If I have 4 trains in motion (and I have some quite severe gradients; 1in~45) pulling reasonable train lengths (7 or 8 coaches) the current draw hovers around the 1.0 to 1.1 amp range.

 

Does this help?

It would be a little higher in larger scales.

But I agree the current draw in stationary locos without lights or sound would be negligible.
