true or false: if a train engineer sees someone or something on the tracks. he or she can stop the train to clear the tracks

Answer 1

False. A train engineer typically cannot stop a train quickly enough to avoid a collision if they see someone or something on the tracks. Trains require a significant distance to come to a complete stop due to their mass and the laws of physics. Engineers are trained to sound the horn and apply emergency brakes, but stopping a train takes time, and often the situation may not allow for avoidance. Safety protocols are in place to handle such situations, but stopping a train to clear the tracks is not generally feasible in a timely manner.
