I'll try on a the small loop first to see if there is a difference. I
have not <i>noticed</i> any speed reduction far from the regulator.

OK thanks for the info, its not just the newness of the one motor. I
don't think they are heavily used--they have had week-long lulls without
movement when I'm real busy. sad.

I am using a 4 track long one plate per piece hill (and motor without
engine or car), just for seeing the difference on hills. I may have said
this before but the motors without engine or cars get better contact and
speed up on the curves while slowing considerably on straight.

| Hmm. I've setup a bigger layout (one floorsworth) and still its a full 9v on the farthest away point. So its not he track. I strongly think its wheels contacting the rails so I'll try steel wool sometime tomorrow and say what happens. -- Peter (...) (21 years ago, 13-Nov-03, to lugnet.trains)
