PDR - Jack and Slomo down the spiral

[owlpool]

Having a 1 in 10 gradient on my line, and really wanting to have live steam I had to make sure that any steam loco was able to travel..s...l..o..w..l..y.. and also be happy when going down the hill.
The Regner geared locos and Accucraft live steam Shays were the answer. They really can go slow especially the Shays. There is a quickening of pace down hill especially if there is a good load behind but not drastically so.

yes, we have a steep bit on a return line which is steep - never actually measured the gradient, suspect about 1:20, where similar precautions are needed - not a problem with a Slomo loco
