Electric buses can be switched for diesel buses but only on Saturdays and Sundays.The CIC will organize on-site meetings with Metro Power Distribution personnel and Contractors to evaluate construction needs in relationship to electric buses and overhead wires.

Overhead wires:

The trolley overhead system operates at 700 volt DC. Overhead height is approximately 16 to 18 feet. State law prohibits any work within 10 feet of the overhead. Contact this office for information on special permits.
