Real quick radius please

ModelRailroadForums.com is a free Model Railroad Discussion Forum and photo gallery. We cover all scales and sizes of model railroads. Online since 2002, it's one of the oldest and largest model railroad forums on the web. Whether you're a master model railroader or just getting started, you'll find something of interest here.


Where a 2.0% grade in HO is considered "appropriate" N Scale is more than capable of a 3.0% grade plus some as you have demonstrated. And yes, I know HO can negotiate greater grades than 2.0%
??????????????????????????????????????????????
Not finding any sensible logic in this statement.
Can you clarify?
 
The only reason I did that test was because a person on another forum is wanting to model a specific railroad that is in the mountains and has steep grades. Everyone was cautioning about grades, and how curves compound the problem, so I devised a test to prove if it could work or not.

BTW, I didn't do a video, but even at a 6% grade, that little 2-8-2 could do it! Even through the 9.75" radius curves. So I thought perhaps demonstrating how well this little steamer handled the curve with a grade was apropos.
 


@JeffH agreed, people are very cautious when it comes to grades and they tend to err on the side of the "norm" or what is "historically acceptable". I think most people under estimate what an engine (in any scale) is potentially capable of. I have to confess, I don't like going over 3.0% grade and am even more wary when it somes to curves.
 
Seems fairly self explanatory to me ... exactly what isn't "sensible logic"?

2.0% grade is considered the norm for HO where as 3.0% is acceptable in N Scale - makes perfect sense to me.
"Normal" and "acceptable" have two different meanings. And could easily be interchanged in your statement (i.e., 'acceptable' for HO, and 'normal' for N-scale). In which case, your statements still wouldn't make any sense.
At least not to me. 😕
