Describe the correct method for securing unattended equipment on a grade exceeding 1%, including all required safety appliances and their proper application.

Securing unattended equipment on a grade exceeding 1% requires specific measures to prevent the equipment from rolling away and causing damage or injury. The correct method involves using a combination of hand brakes and, if necessary, additional safety appliances such as wheel chocks. First, determine the direction of the grade. This can be done using track charts, grade markers, or by observing the natural tendency of the equipment to roll downhill. Second, apply a sufficient number of hand brakes. Hand brakes are mechanical brakes that are applied manually to the wheels of railcars. The number of hand brakes required depends on the grade, the weight of the equipment, and the type of equipment. Railroad rules typically provide specific guidelines for determining the number of hand brakes needed. A general rule is to apply enough hand brake....
