As my around the wall layout was coming together I took an old 4 X 8 switching display module and tacked it on to one of the TT approach tracks for a 1-2 or 3 car switchback small industrial park. The TT is in the adjacent staging room.
Well as it sometimes happens, a bug bit me to add another terminal so after the fact I added a 4' X 13' module with additional rail served spots.
Now I had a dilemma, the switch back off the TT lead was totally inadequate to feed this upgrade. I needed to connect directly to a through track, as suggested by my flex track nailing template.
Not wanting to do a major rip out redo I was looking for a clean way to achieve this goal. Sooooo... I pulled out some wrapping paper and crayoned over the entire existing track configuration and sent it to Brad at Signature Switch.
He conjured up a CAD and emailed to me a full scale drawing which Kinkos printed to check for fit.
After approval he produced this one piece combo.
Curved wye and double curved diamond
After breaking out the Dremel I now have a straight access to the branchline as it disappears into the staging room.
I can back any combo of cars over this trackwork trouble free
