Wow! Thank for the construction tips! I guess I may be one step ahead then. My Big Boy's tender operates on an end slider of two attached wheelsets. I have noticed a slight uplift going in and coming out of curves, but nothing major. I guess the (...) (25 years ago, 27-Mar-00, to lugnet.trains)

Lar, When I read your comment I jumped up to check it out. The center slider[1] evolved from an unattached wheelset, which is why it had to be in the center. When you said end slider I thought, "Power for my SD40!" I did not try to make it, but (...) (25 years ago, 27-Mar-00, to lugnet.trains)

Today, when my green trolley rearended my red trolley I decided to test my motors. I ranked them in order of speed. Then I thought that it would be bad to have a fast motor paired with a slow motor. I thought that pairing motors with dissimilar (...) (25 years ago, 27-Mar-00, to lugnet.trains)
