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.
