Any sadistic track builders want to take this on?

This is one of those 'can't happen but here it is' photos.

This is the PRR Irvine(ton) junction, looking east; Renovo Erie-Lock Haven line left to right, Buffalo division Oil City-Olean diverging to bottom (south).

You'll see it goes through a REVERSE CURVED, double-track, through girder bridge, and immediately off the end of the bridge, a wye switch diverts BOTH mains south. 

And in the middle of the entire mess, a curved diamond.   What you can't see is behind you is the Irvineton PA passenger station, and the other 'leg of the wye' that makes this into a three-point wye with two double tracks.   

I.e. the PERFECT ultimate T-trak wide-curve junction. and one to create both an operating polarity nightmare and a track building nightmare.    It's on my bucket list for a module.

So, you know I only believe in Kato track to get on and off a module.  Within that, other than at least Code 65 rail, it's wide open as to who, if anyone is capable of assembling a custom double wye switch with a diamond on a curve as an open custom build challenge.   Contact me if you think you can make it to fit, I'd buy it.   The diamond on the curve is what baffles me.   But I've seen worse done here.

Oh, and yes, they did have a major derailment here in the 40's, in case you're wondering.

Here's the 1951 PRR track chart to confirm the layout.  See at Irvineton.  But that 'diamond on the  reverse curve with curved switches....' wow, today that would get you fired on a design from any Class 1 in the US.

The track behind (on the truss bridge) is the parallel NYC "Valley Branch" Dunkirk to Titusville.

The girder bridge single main line on the right side is still there and operated by B&P, it is a curved through girder, line south gone in 1971, passenger station in 1980.   Tower taken down sometime after 1965.

Prototype for everything?

Its doesn't look that bad, or all that unusual really. Its just a double track mainline that splits into two routes isn't it? You always need a diamond with that. The curves don't look too bad either, go slow when diverging but beyond that what's the big deal?

Now I do spend some time with the railways of Britain where this sort of thing is very common, even today, and that may be affecting my sense of normalcy. But I still don't think its all that bad. I look forward to seeing your module!

We have a full double tracked Elvas Wye modeled on our club layout.  So, the foreground of the photo times three.  Handlaid in the 90s.

I'll agree that it doesn't look that unusual, or that hard to build.  If one can build turnouts, the crossing should be easy.

I'd try building it using standard Atlas code 80 wye turnouts and a 20-degree or 30-degree crossing.
Cut the track off just beyond the frogs in both the turnouts and crossing and connect them with curved pieces of flex track.
The short sections of trackage through the crossing will be straight, so you'll have to determine if the appearance is acceptable, or not.

I hand-laid a double-curved crossing on an NTrak module I was helping to build, some 25 years ago.  Scavenged plastic ties, code 80 rail, pliobond.  @peteski can witness, he did some exquisite detail work on that module.

If I can do that as my first hand-lay, you'll have no trouble.

If you're using DCC, and both tracks are fed from the same booster, the crossing frogs on the outside can be solid, which helps; the rails there are the same polarity and don't need insulation from each other; you will have to think about occupancy detection, if that's a concern.  I think (but cannot prove) that a dual juicer wired as a reverser can handle the inner frogs, if live frogs help your situation.

Good luck!

Yeah, that 12' corner with a passenger station is an amazing feat of design and construction!
