How easy is it to cause a derailment?
<|assistant|>
It depends on the particular type of derailment and the train and tracks being used, but in general it can be quite easy. Small obstacles like rocks or sticks thrown onto the track or even excessive heating of the rails due to a hot pavement or track could cause a derailment. Additionally, defects in the track, rails, and/or equipment, and strong winds, can contribute to a derailment.
