Can't speak for model railways, but the Roaring Camp and Big Trees =
Railroad, Felton, California which uses steam ex-logging locos claims a =
grade of 1 in 12.  Having ridden on it in 1997, it is certainly steep.  =
Tramways, and electric railways using single vehicles can also be quite =
steep.  The steepest in Australia (ignoring the Balmain wharf line which =
used counterweight assistance) was the line to Neutral Bay wharf, which =
had a ruling grade of 1 in 8.5.  This required trams to be equipped with =
special braking systems, at first they used mechanical track bracks, =
then a corridor car with dynamic brakes was employed for the final years =
of the line.  I'm sure that there are electrically worked Swiss mountain =
lines and perhaps the Chamonix line (France), using single coaches, =
which are steeper than 1 in 12 using adhesion.
