4 Pack PRR Plan 57641 Small Circular Culverts Now Available at Keystone Details

[Lemosteam]

You may recall several years ago I was thinking of offering cast versions of the subject offering.  Casting difficulties and shipping worries made me abandon that idea.

Enter Keystone Details!  The Culvert is based on PRR plan 57641 of the small culverts (large also coming soon). 



The 4 pack can be ordered here:

That might get rather expensive if 3D-printed.

Sheesh.  I just finished designing them, LOL, but here's the cast one I made back when. 



Still trying to find a proto photo...

True, I was thinking that too, but think about this:

You can build just about any size or curvature for a PRR stone bridge using Chooch flexible walls:

The challenge is in doing the arch.  What if you could 3-D print just the arch stones in proper PRR curvature?  Case in point:
