Would you explain the 300 feet of interlock part?That's the distance between signals on either side of the switch. It's usually a little shorter. I've approximated this distance 3 ways. I've looked at the chaining marking on the signals. I've seen trains on the switch and used the car lengths between the signals as measurement units. I've also viewed outdoor switches on Google Maps satellite view and used their measuring tool. |
