Anyone know of an easy way to measure the length of track on a layout?
I used a measuring wheel. I had it for when I did landscaping and used it to get yard size for ferts.
that could be hard for you seeing you have all mountains.
What you could do is tie a peice of string to on eof your locos have it pull it thought the mountain then measure it. Use a tape or wheel for the open sections. It will not be 100% but will get you close.
I use my measuring wheel. That could get pretty tricky on your layout, Ray.
I know Bruce and others have adapted bicycle speedometer computers for speed readings. They also have distance measurements built into them.

75.42 and 72.28 feet.
Smaller than most you use to put your trains on the track.

Ray,
Get a hold of Bruce Chandler, I think he built a car to do what your asking for. Maybe he will post here on it.

Yep, just use a bicycle speedometer/odometer. You can easily specify the diameter of the wheel in inches; just use the correct one for your scale. Attach a magnet to the wheel and position the sensor next to it. Then just run it out on the layout.
