Conduit current collection

Conduit for current collection between the rails of streetcars in Washington, D.C., 1939. Washington installed the system in 1895[1] and it remained in operation until 1962[2]

Conduit current collection is an obsolete system that was used by some electric tramways to pass current to streetcars via a "conduit", a small tunnel under the roadway. Modern systems fall under the term ground-level power supply.
