Making the Grade

[Anonymous]

Can someone tell me what month and year that Classic Toy Trains ran an article about how the determining a grade?

I'm almost positive it was in the last 12 months

If you are looking for the calculation, it's really quite simple --- rise in inches over run in inches equals percent grade. For example, a three inch rise in 100 inches of track run equals a 3% grade. If you know two of your variables (such as desired height and grade), you do the math and calculate the third variable (amount of running track required to rise to that height with your desired grade).
