§870 Trolley Wires and Trolley Feeder Wires

Summary

Trolley wires and their feeder wires must have cutout switches no more than 2,000 feet apart and near the start of any branch line. They also must have overcurrent protection. Trolley wires, feeder wires, high-voltage cables, and transformers must not be placed beyond the last open crosscut and must stay at least 150 feet away from pillar workings. Wires (including bare signal wires) must be insulated where they go through doors or stoppings or cross other power lines. They must be guarded where people work or regularly pass under them, on both sides of doors and stoppings, and at man‑trip stations. The Secretary or an authorized representative can require other protections or better methods. Temporary guards must be used when people work near these wires.
