Tight Radii
New Member
Hi guys, I've got a small (33" w by 72" l) oval layout and I've got an issue with the dimensions of one of my switches.
My layout's curves are mostly 15 inch radius Atlas code 83 22.5 degree pieces, with a single 18 inch radius piece in each of the semicircles. The two 18 inch radius pieces are diagonally across the layout from each other, where a curved piece is missing in the picture and diagonally across from it in the lower left corner. I want to replace the missing 18 inch radius curve piece with a switch so that I can have a track continue straight off the board to connect to another module. I can't use a switch with a larger radius because of the width restriction. I also want to use off-the-shelf track pieces if possible.
Basically, my issue is that the packaging for the Atlas 543 Right Manual Snap Switch plainly says that it is a direct replacement for an 18 inch radius curve piece - and even shows this in a diagram - but it is most certainly not. You can see in the picture where I've laid an 18 inch radius piece on top of the switch that they're not even close to matching up.
I'm not married to Atlas, brand-wise. Peco and Hornby seem to make a 2nd radius 22.5 degree frog angle turnout, but both of those are code 100 rail.
Does anyone know of a code 83 switch/point/turnout that fits my needs?
