Hi all,

 

I have a simple layout around the tree - two ovals that are connected via O-60 Fastrack switches - almost like a crossover.  Each loop is powered independently with a separate transformer.   I figured I'd use the quick block trick and removed the jumper from one of the two connected switches.  Then, I observe the following behavior: 

 

When the engine on the outer loop switches onto the inner loop, it shorts the outer loop.  It picks up power on the inner loop after a lurch, and continues on its way, but the outer loop is shorted - I have to reset the transformer.  

 

I fear I have a fundamental misunderstanding of the magical 1 3/8 jumper section.   I should note that I am not using an extra piece between the switches - I used the included jumper piece in the box and connected the switches directly with only one of the jumpers removed.   Do I need to remove the jumper from each switch?  I see the center rail break on the outer switch, which should be a good thing, but why am I getting the short?   

 

bTW:  These are MTH DCS Protosound 2/3 engines.   

 

Thanks in advance - not sure what I missed/misunderstood here!!!

Well, now I'm not sure... I just watched a video that explained the whole phase thing, I'm I don't think I did any of that stuff.   The video seemed more directed towards fixed/variable power and accessories.  All my power is "fixed" out of the TIU.    Would I need to jumper the TIU inputs/Outputs?  

 

Thanks for putting up with my thick-headedness...
