using a reverse magnetic force
lets say side 1 is the hill
side 2 is the train
1 must have a N or S
2 must have a N or S
side 1 and 2 must either both have N or S
so the magnetic force slows the sliding of a train
hoped thats what you mean
If you are sliding down the hill on a sled, you are sledding.
there is a type of device on the train of the rollercoaster that is known as the "chain dog". the "chain dog" grabs the hill so it doesn't roll backwards, but it still allows the train to go upwards by the pulling motion of the chain (note: the bolded "chain" is not the chain dog, the chain dog holds while the regular chain pulls)

Last Train from Gun Hill was created in 1959.
Richmond Hill train crash happened in 1950.
The duration of Last Train from Gun Hill is 1.57 hours.
tobogganing is a fun activity which is like sledging.a toboggan is used for sliding on a snow hill
Hines Hill train collision happened on 1996-01-14.
Underground (tube) train.
When facing down the hill - turn the wheels toward the curb when facing up the hill - turn the wheel away from the curb
To increase the number of snowmen destroyed by the sled sliding down the hill, you could make the hill steeper, place more snowmen in the sled's path, or increase the speed of the sled. Additionally, you could add obstacles or ramps to the hill to cause more collisions and destruction.
Friction is the force that allows you to walk up a hill without sliding back down. The friction between your feet and the surface of the hill provides the necessary grip to overcome gravity and maintain your position.
