Default Geared live steam and grades

The Heisler has me intrgued but I was wondering without R/C what
kind of grade would it (or the Shay or Climax) be able to tackle?

Trying to think about grade maximums (up and down)

Thanks
Lorna

I don't know about maximum grade but my Shay will climb a 7% grade without seeming to break a sweat and it's traction effort is greater than a Connie (2-8-0) by a car on 4% grades.

I have several friends who run geared locos on my RR with 3 1/2 % grades. They run up and down the grades at pretty much the same speed with no change in throttle setting.

All I can say is that the grade just before Whittier (or is it Whitticker?) on the Cass Scenic Railway is just a bit over 10%. It is relatively short, but the prorotype geared steamers shove their trains up that grade daily. I suppose the models can do as well for a similar short distance, say 25 real feet or less.

Thank you gentlemen. The grade on paper would be no more than 2.5% but just trying to see if I need to go down (I don't have to go up).

I have seen the Accucraft Heisler pre-production prototype run on a landscaped layout with grades. It behaves better than a rod loco but definitely speedier than a Shay or Climax. The gear ratio is clearly higher on the Heisler. The Heisler had a tendency to hurry down the hills and creep back up whereas the Shay experienced no significant change in speed or performance. I don't want to deter you if you like the Heisler. The grades you are describing are not that severe so you most likely will be fine. The WSL Co #3 Heisler is a really cool looking loco and we had a great time watching it on the layout. I already reserved one myself. For the record, Henner Meinhold (also an MLS member) has a layout with a switchback around 10% and we have run Shays and other misc. geared locos on it with no issues (even hauling steam donkeys up to the top!) Hope you join us gear-heads. We have the most fun ;-)

Right now the only design is on computer using some rail CAD software.

I figured the Shay was slower or lower geared. From the looks of what I have in mind the maximum grade will be around 2.5% if that is any help.

I like all of the geared locomotives but the Heisler holds a special place because I got the privilege of riding behind and a quick cab tour at the Roaring Camp and Big Tress and also when I had a little bit of HO, the very first brass model that my father bought me was a Heisler.

Thanks for the information.

Lorna
