video of the finished dual gage crossing in operation

It took about 20 hours to build this dual gage crossing in the Delta yard, which now opens up some new areas for both narrow and standard gage service. To power the frogs I used a "Dual frog juicer", which simply reverses the polarity of the crossing frogs whenever needed by an approaching train from any direction. The crossing is built using code 83 rail because that matches the curved mainline running through it, although the dual gage route is code 70 outside of the crossing itself.

Here's what it looks like:

And here's a video showing it in use...
