 Yes, Palm Garden Loop had  a left turn protection signal that
was removed when the South Busway began operations. It was not
long after thst that a looping PCC car collided with a
northbound  bus killing four people in the bus and sending
many to the hospital. PCC motorman not hurt.
   I had required Pat to install signals on the portion of the
rail line used by the busway from South Bank to Frederick St.
or Glen bury. Buses needed induction loop controlled signals
that had to be red all the time except when an approaching
vehicle set them green to go red again as it passed. The
induction loops were not as fail safe as the track circuits,
The red approach meant slow speed approaching signals,   I did
not know they removed the Palm Garden Loop signal until too
late.

Waiting for a bus is about as thrilling as fishing,
        with the similar tantalisation that something,
                sometime, somehow, will turn up.
