Sir, A 25 grade is @" every 100 " and a 3% is 3" every 100' and as a Civil engineer I do know this is correct.Thanks Bert Cutler

Since my trigonometry is a little rusty, I went to double check my results with an online calculator and the results don't match. As a matter of fact, the online-calculator gives me close to 50% more rise then my own calculations. Here's what the calculator determined; Over a 4 foot module with a continuous slope; http://www.csgnetwork.com/righttricalc.html A 2% grade =1.68 inches of rise A 3% grade=2.52 inches of rise (The actual Marias Pass has a 3% slope in places) This seems to be a greater increase then I expected. Now, even if this is correct, the first four modules won't increase at this rate since they will each include a transition from level to the maximum slope. How would I calculate the amount of horizontal space necessary to transition to the maximum slope and how much height would be achieved over the course of the transition zone?
