Mojave sub trackside signs

I guess you mean that is what they are used for on the TS12 route???

In real life they are fractional milepost markers as NCKilla333 said.
-I have never seen them used like that. That would be so many signs per mile of track. But based on this little info I found you may be correct...

-But me personally, I'm still going to use them around grade crossings only. I don't think a RR could afford putting in another 3 signs every mile... unless it was for a safety reason.

Use them as you like.

What I said was how they are used on the Union Pacific Railroad in the real world. I am an Engineer with UP and I work in Southern California. The signs are used as I stated.

UP obviously can afford to install the extra signs between mileposts because they have had them for several years. Before the 1/4, 1/2, and 3/4 signs were installed there were white bands on the lineside poles with 1 band denoting 1/4 mile, 2 bands 1/2 mile, and 3 bands 3/4 of a mile. The bands on the lineside poles were also used in certain places on the Southern Pacific Railroad.

Here is a link to a UP 1 page document showing the milepost markers:

BTW the extra signs are used for information only and not necessarily safety although more information can equate to more safety.

-I was going to ask my southern California friend about this, that also works for UP, out of Colton, but since this post came first, I'll just have to go with what you say, so you win sir.

Besides grade crossings the only other place I've seen them is before a switch coming up for a siding off of the mainline. They have them here in Tehachapi for the summit switch.
