Hi Peter!
But that is only measured without electric load. Even if you have a really high
resitance in the joints of the track, you still will have the 9V at any given
point of the track as long as you have no parallel load on the track. A motor
might have much less than 9V at that far away point of the loop...
Leg Godt!

P.s.: I think steel wool is a bad idea to "clean" track.....

| (...) You can test this for yourself. Measure the voltage of a 9v battery with your voltmeter, then measure it again in series with a 10K resistor. It's still 9V! Now, think of all those track pieces (and joints) as tiny little resistors... :-) Mark (21 years ago, 14-Nov-03, to lugnet.trains)
