Congested Interchange & Logging Track Plan
 
I've been tackling a combination problem with my track plan. It primarily involves the 'intersection' of 2 mainlines with the container yard and the logging area. Originally it was a bit simpler,... involving a crossover between the 2 mainlines at the base of a reversing loop of track that extends out into the helix. Thus a train could go either way around that loop, and when it came back to this crossover it could take either of 2 routes back thru the container area. It utilized a pair of Peco double-curve turnouts.

Then I came along and added some complication,...3 more tracks connecting with the 2 mainlines in that area,...congestion. Two of those tracks are for container cars to enter and load in the container yard, and the third (if wanted) is a parking track for a pair of Santa Fe diesels dedicated to working the container area. Then at the bottom there is the access turnout/track leading off to the left to the logging saw mill and logging turntable.

With all of this extra congestion and tight grouping of turnouts I had to depend not only in lining up the paper templates, but also on physically getting the actual turnouts out and connected them together to assure that I could make this plan a reality. I was dealing in angled tracks (non-straight) and double curves, and each little twist here was an awkward twist somewhere else. It was a puzzle. I ended up making good use of those Peco dbl-curves. I also discovered one spot that was better off with a std turnout.
 
Since two of the tracks running thru this congestion are 'mainlines' I wanted to keep the curved tracks as broad as possible. The use of the dbl-curve Pecos and the large radius std Pecos does that, and the connecting tracks are in the range of 26”-29” radius. The container track feeders have some 24” spots in them, but generally that is the smallest radius curve in any of this area.
 
There are 4 dbl-curve Pecos in this photo,....nice flowing configuration

This next photo shows some of that same 'congestion', plus 2 tracks off to the left. The one with the logging engine siting on it is a holding track for the gallows turntable.

That other track is the entrance track to the logging area. It comes off the mainline with another dbl-curve then makes a 15”r curve around to the left to that 'Y' turnout.

That little switcher engine...

will be servicing the chip loader, and will be picking up rough-sawn lumber and taking it on a zig-zag route over to the milling plant in that corner (flat or a photo on that wall) where it will be packaged and loaded onto mainline lumber cars ….centerbeams, thralls, etc.
