Yes Woodie, but every traction tire is a wheel that can't be relied on for electrical pickup. Don't know about snot (Bullfrog type) but can't believe that it is going to make contact any more reliable.

Now we DO know how to overcome bad wheel/rail contact though, don't we---

Herb-well, yes..we do know how it could be done. A properly equalized locomotive mechanism would pull correctly and maintain electrical continunity but how many RTR locomotives have this feature? I suspect NONE do. That other alternative will be not discussed here. There's a thread for that.

How about using a hoist...I know that works!

Is a severe grade a 1%?

Nope, a severe grade is a 10% like I have on the main line...the hoist incline is 15% or so.. The higher the number, the steeper the grade. A 1% grade is barely a grade.

Traction tires are not prototypical.
