§870 Trolley Wires and Trolley Feeder Wires

Summary

Require cutout switches on trolley and feeder wires at intervals no more than 2,000 feet and near the start of every branch line. The wires must have overcurrent protection. Trolley wires, feeder wires, high‑voltage cables, and transformers must not be placed past the last open crosscut and must stay at least 150 feet away from pillar workings. Wires and bare signal lines must be insulated where they go through doors, stoppings, or cross other power lines, and they must be guarded where people work or pass underneath, on both sides of doors and stoppings, and at man‑trip stations. The Secretary or authorized representatives can require other protections or better methods, and temporary guards must be used when track workers are nearby.
