Hmmmm, this is pretty goofy. I have three of these sections and two more on a xmas layout. Can’t find a product number on them. Don’t remember where I got them. Looked up the FasTrack listing and the closest I could get was the block section piece; 6-12060. I’ll let others advise if that piece will work the same way, but my guess is that it would. I included a screen shot of that one. It breaks all three rails. If there’s a problem, hit me up with an email in my profile and we’ll work out getting you one of these. Just thought about this block control, and figured you’ll actually need two, one at each end of the block.
