Overhead signal on short mast. Example of
a short cantilever mast used to clear tram wires. The attachment on the
right of the overhead signal is a No Right Turn sign lit at certain times of
the day.

Single red arrow at a railway crossing.
At many locations where railway crossings are located beside an
intersection, the traffic lights are linked to the railway signals to
prevent traffic entering the road with the railway crossing.
More examples on the operation of such crossings shall appear in the
railway crossings section of this site when it is added.
Yarragon, Vic. |

AWA signal with louvres. Traffic light
made by AWA with tunnel visors fitted with louvres to help prevent the sun
from shining on the lenses and creating a 'sun phantom' effect making it
look like all lights are on.
Preston, Vic. |

 |
Bottom mounted signals. Relatively unusual are these
signals mounted on top of a short mast arm in order to clear shop verandahs
and tram wires.
Hartwell, Vic. |
 |
 |
Large backplate. The overhead signal here has a
larger style target board on it than usual. Although not unique, there are
not many like this around. Note the lower signal has 12" lenses whilst the
overhead one is 8". Yet the target board appears larger. Abbotsford, Vic. |
 |
Early Eagle signal. Example of an earlier
kind of signal made by Eagle Signal Co. Interestingly it has survived into
the 21st century in Melbourne's CBD without a target board. Signals without
target boards in Victoria are very unusual today, although were how all
signals once appeared. Melbourne, Vic. |
 |
Another Eagle signal. This one has the
(presumably) decorative sections top and bottom which make it a little
taller overall. Melbourne, Vic. |
 |
 |
Yet another older Eagle signal. As above.
Melbourne, Vic. |
 |
Signal with sign. Yet another example of
an older signal still minus target board in Melbourne's CBD. |
 |
Pair of Eagle signals. Topped by a One
Way sign in the US style is this pair of older signals outside Her Majesty's
Theatre, Melbourne, Vic. |
 |
Not In Use. Signal with a NOT IN USE sign
used to indicate the signals have not yet been turned on, as opposed to
having failed. Hallam, Vic. |
 |
Interchange not in use. More signals at
the same location with Not In Use signs. This freeway interchange at Hallam,
Vic. had yet to open. The signals were erected about a year before opening
though. |
 |
Temporary signals. In conjunction with
the above freeway works, the Belgrave - Hallam Road was duplicated. The
photo shows the temporary arrangement when only one side of the road was
open. Signals are all LED. The overhead signal is not powered. |
 |
LED signal. Light Emitting Diodes (LEDs)
have longer life and much lower power consumption than incandescent globes
and as such, are becoming popular in traffic lights. The photo shows that
the light consists of many smaller lights. Hallam, Vic. |
 |
LEDs changing. LEDs tend to switch on and
off almost instantly compared to the slower on and off of globes. So getting
a photo with the green and amber at once was surprising (I wasn't trying to
get this effect). I have noticed that some LED signals do change slowly, but
it seems to be an effect of the signal controller. Hallam, Vic. |
