Ignorance is bliss... There's an app for that...
"To succeed in life, you need two things: ignorance and confidence." Mark Twain
There I was.. all smug and confident that I had this whole helix grade thing figured out. I measured and divided and was careful (so I thought) the second time setting the grade. I got all the sub-roadbed installed, the cork roadbed laid down, started laying track and I even ran an engine a short distance on the top loop. All was well and right with the world.. until I got my new iPhone..
I've been exploring all the features and apps available and I downloaded a bunch of model railroad related apps. One of which was a gradient level developed by Kevin Snow at MynaBay.com:
I knew I had some slight variations in the grade but I figured they were minor. I started checking the spots that looked a little steeper than the others and I found short sections of 4% or more (by short I mean about one foot in length). Most of the grade coming up the helix were within 2% with a few spots less than 1%. I was devastated and even now I'm not totally sure where to go from here. If I hadn't upgraded my phone, and picked up this app, I wouldn't have known. I'm thinking of laying the rest of the track and testing a full 12 car train with the heavy 2-8-0 to see if it has a problem with the short steep sections. After these sections the grade levels out considerably so maybe it will be OK. If not then I'll have to loosen up the loops and try to even them out, AGAIN.
