Thanks, Lynn, for the input. Your suggestion makes perfect sense.
I went south to north and west to east, which is the standard for the (highway) transportation industry. We also use survey stations like 1 + 00 for 100 feet or 10 + 00 for a thousand.
The railroad has their mile markers and I wondered if they did their switches using a mile marker plus something for switches, but then how would you do the switch yards? I noticed their mile stations seem to run from some major yard or something, not necessarily in any standard direction. This would be in line with your suggestion.
Thanks again, lasm
