Curves on TT-Tracks have been an evolving issue.
Our first setup back in 2011 showed that the curves on the small corner R1/R2 were too sharp.
We immediately jumped past the Medium Corners R2/R3 to the Large corners R4/R5. We used these for years even though they were still rather sharp curves. We had many good displays with these corners.
Then in 2017 came the first of the new larger curve modules, the 45 Degree Modules R6/R7. These were good although their design brought the outer curve close to the edge of the module. These were good but still lacking something and needed unsightly trimming to fit in a standard module transportation box.
Designed and built in 2018 and used in 2019, the thirty degree curves R10/R11 were what we were looking for. The trains look really good on these curves and they fit in a standard module transportation box.
The next issue is that we only had two good sets of corner modules. Unless we used an older Large Corner R4/R5, we could only build a U or C shaped display. We need another set of corner modules. Build another set of 30 degree modules or contemplate the next size larger.
In late 2019 doodling started on the 22.5 corner concept. Sadly Covid arrived and with it Covid malaise. With no prospect of a setup to spur progress not much was done in 2020/21. Not much of anything was done those years.
With the prospect of a non-public setup in February 2022, interest has been sparked.
Full sized paper templates were made to get an idea of how they would look.
They look great, Trains will look fantastic on the R15/R16 (~36" - 37 1/2") curves.
The question is scenery.
I liked the scene on the Diamond shaped large corner so two modules would be used to recreate it. One with the stream and bridge and the second one with a cluster of Railway MOW buildings.
We don't have a lot of water on our modules, Two streams, one bridge on one of Terrys modules, and Bjoerns bridge.
One thought is to use one or two adjacent modules to model the tracks on a causeway through the water. Trains would look good in this scene and if we could get a good enough finish on the water we might be able to get pictures of the reflections of the trains.
Much to think about.
