Max allowed transverse accelerations at hump and fly shunting, a v = -3 m/s 2
According to the table above the worst case appears when α = 60°, and β = 30°. At these
angles the maximum allowed transverse acceleration is 4.9 m/s 2 <strong>for</strong> hump and fly shunting
when the vertical acceleration is discarded from, e.g. a v = 0 m/s 2 .
The largest allowed longitudinal accelerations during hump and fly shunting are shown
below.

Max allowed longitudinal accelerations at hump and fly shunting, a v = 0 m/s 2
The corresponding allowed accelerations when the wagon is not subjected to hump and fly
shunting <strong>for</strong> both transverse and longitudinal direction are shown in the tables below.
