BlueLine Simple CatenaryFixed Termination System

This included installing switch castings with outside runners to accommodate pantographs

As construction was proceeding Northward towards “Uptown” the cars were re-equipped with pantographs thus deleting the needs for trolley frogs and runners on the out side of the casting, thus slightly changing the catenary

SCFT – Single Contact Fixed Termination

FYI There are actually two distinct areas to this alignment; a non-revenue section connecting the line to the Light Rail Line and second the alignment on Trade and Hawthorn Streets.

Today there are two feeding substations, reconditioned from the old museum line transmitting at 650 Volts DC. The alignment is setup to be fed also from the Light Rail Line if the situation arises.
