If you remember. I ran across that string of tie cars last February and posted the picture on my blog. After a few conversations with Brett Isaccs who developed the N Scale models I found that these models were developed from pictures and decided to do the same in HO. For those of you that don't get Running Extra, these cars are part of a complete train that picks up old ties while the train is moving The locomotive is a rebuilt SD40-2 done by Relco here in Iowa.

As I'm from the Midwest, I'm very used to seeing loops for grain and coal loading and unloading. But this arrangement is outside of Lordsburg, New Mexico. Anyone have any clues what this might be used for? Google Earth shows four UP GE's, a bunch of tankers, some (I think?) ore or ballast cars, and a fair number of boxcars.

I don't have a very big layout so as a outlet I've been designing N Scale 3D printable items you put together.  They are designed to be printed on a PLA printer with 0.4 nozzle.  I concentrated on making the parts functional and practical as ultra fine detail just isn't possible with this type of printer.
