Theres a formula and one of the factors is called cant deficiency. This number affects curve speeds quite a bit. In the US, the max normally allowed is 3 inches, and in many places only 1.5 is run. The FRA allows 6 under waiver. France allows 8 and Germany allows 11 (roughly, the real values are in mm). I think the German case requires special certification and en-route weighing. To someone not used to such high numbers, it is an eye opener the first time... |
