(a) Locomotives; speed. Cars shall not be moved except by a locomotive, unless under direct control of an operator. No cars shall be pushed ahead of the locomotive underground if it is practicable to draw, and all locomotives shall be provided with headlights and gongs.

Trolley poles shall be trailed wherever it is possible to do so. No locomotive shall be driven by a person under 21 years of age.
