(1) Guiness Book of Rail Facts and Feats has steepest adhesion grade as =
1 in 11 on Chamonix between Servoz and Chedde (France).

(2) If this was an Olympic event I'm sure Lambing Flat's little Krauss =
would be disqualified under equipment rules for adhesion working.... LGB =
rubber tyres seem to me to be in the same league as sprung shoes for =
high jumpers or flotation suits for swimmers. On the other hand, I bet =
they have the sanders going full time on the Chamonix 1 in 11!

which are steeper than 1 in 12 using adhesion.
