On this page you will find some N Scale crossings by Nskale. He asked if I would post the files on my thingiverse account and I said yes, so you can find them there. I'll let him explain more about them....
Well, I went back to the intermodal scene because I got an idea for some added detail when I did some research on RR crossing designs (modern). I came across the modern concrete panels/inserts you can see in the attached pic and I wanted to add some inlays like that for the track where there might be vehicles crossing in the area. Before, I had made them for small road crossings with pieces of balsa, but it turns out it's a perfect task for a 3D printer.

I designed them to fit in Kato track and to be self-centering allowing for clearance for the wheel flanges. So you see the bottom is smaller than the top, just like the real one. The way track is manufactured, there are small nubs at each place where there is a molded-in crosstie (where it supports the rails). I say designed for Kato track because I don't know the distance between the nubs for other track. It might fit as-is or it would be a trivial matter to adjust the width of the bottom for an exact fit. So, in order for it to fit in all the way down, the bottom is dimensioned for the distance between the "nubs". Above that, the top is dimensioned for the clearance needed for proper fit for the train wheel flanges.

And, to make it more complicated (thanks Kato), the place where the track pieces fit together is even smaller on the bottom. This is caused by the plastic joiners and the distance they stick out. So, there are two possible inlays that I might need to use.

For straight track, it's a simple matter to scale the length in the slicing program. That means that only one part needs to be made in the CAD program for all lengths you might need. For lengths longer than the width of the printer bed, make more and glue in end-to-end.

Nskale did a really nice job on this. Again to see more info on these and how to use them go ( HERE ) and you can find a direct link to the files on thingiverse.com ( HERE ).
