.......when you are doing your bench work?  I understand how to determine the height-distance thing but getting my grades to be a CONSISTENT say 3% is very hit or miss when it comes to curved grades.  A straight grade is easy but when the tracks curve it gets hard.  Looking for tips.  I’m using 1/2” plywood with a layer of 1/2” Homasote on top as my roadbed which is about 4” wide for single track.

Copper king mine has a mill area, but nothing like the two large mill for the Utah Copper (Kennecott) Bingham canyon mine, I will show them both.

Before my recent hiatus from working on the layout I could have sworn I had my test version of DCC++ hooked up and running and I did at one point. I remember having to go back and catch a couple of feeder drops on some spurs and gaping some frog rails on my Peco turnouts.

Hello everyone!

I am modeling the Missouri & Arkansas railroad and I would like to have an ACF Motorailer but of course none are available and my scratch building skills are not good enough. I wonder if it would be possible to 3-D print a shell that could fit a existing powered unit. The Bachmann doodlebug is very close dimensionally and this is what I had in mind for the power unit for the shell. Have any of you had any experience with something like this? Is there a 3-D printer out there that you have worked with?
