Hello All,

I think that I understand the concept of DC Block Control and would like to run through my thoughts to see if I am correct, before I follow through on my plan.

Using the "right hand rule" where my right rail is the (+) lead and the left rail is the (-) lead, all I have to do is replace the metal joiners with plastic joiners, on the left rail of the two track pieces that bookend the segment of track that I want to "isolate", and then simply attach another power pack to the segment that I "Isolated".

Is that correct?

Your assistance is appreciated.

Thank You

Hunt,

Thank You for the quick response and for teaching me some correct terminology! 

Hello All:

I am in a "similar" situation. I am just starting out and going slow. I purchased the Bachmann HO Thoroughbred Electric Train Set with the F7 Diesel locomotive. The set comes with 18 inch radius curves (E-Z Track ) to complete the oval, but I would like to purchase the 15 inch radius curves to reduce my overall width. I would like to know if the locomotive and freight cars that come with that set will function nicely on a 15" radius semicircle?

Follow up question:  Can I start a turn using 18" radius E-Z track and then make the turn "tighter" using 15" radius E-Z track to complete the turn? 

All responses are appreciated.

Thank You
