- On steep grades the friction between the wheels and the rails cannot apply sufficient adhesion to the train's wheels so as to overcome gravity, and the train is in danger of sliding down the track.en.wikipedia.org/wiki/Steep_grade_railway

Metros and pure commuter railways often also allow steeper gradients, over 4%, for the same reason. High-speed railways commonly allow 2.5% to 4% because the trains must be strong and have many wheels with power to reach very high speeds. See more
The inclusion of steep gradients on railways avoids the expensive engineering work required to produce more gentle gradients. However the maximum feasible gradient is limited by how much of a load the locomotive(s) can … See more

Steepest railway gradient (adhesion) - Guinness World Records
The steepest grade traversed by an adhesion railway (one driven by the friction of wheels on rails) is 1 in 7.2 (13.8%; or around 7.9 degrees of angle). This is found on a street called the …

- Traction or friction is reduced when the top of the rail is wet or frosty or contaminated with grease, oil or decomposing leaves which compact into a hard slippery lignin coating. Leaf contamination can be removed by applying "Sandite" (a gel–sand mix) from maintenance trains, using scrubbers and water jets, and can be reduced with long-term manage...
