Re: Re: Melbourne Z41 And The Chemist

In the Southern Summer two years ago, tram 41 was working the next to
last outbound (down) trip of the night on the 72 line. Melbourne
practice had in the past been not to dawdle in running times, especially
for the last trips, and car 41 was carrying out this tradition.
Melbourne also has a large number of crossovers (shunts) at
intersections of two routes, making the number of curves in the
intersection lower. Before #41's arrival at Glen Ferrie and Commercial
Roads, another pull-in tram had crossed over from the inbound line to
the outbound and turned the corner into Glen Ferrie to go to Malvern
Depot. The switch (points) was left open, but when number 41 came
roaring up the street he didn't see the open switch and entered the
intersection at an estimated speed of 55kph.

Well, well, well. Full width (between rails) double yellow lines means it
is a Compulsory Stop. (not sail through at 55 km/h)

Might even make a list of tramway markings.


* Two Full Width Yellow Lines - Compulsory Stop, found at all facing points,
end of line, Blind Institute, City Intersections.

* One Full Width Yellow Line - Fouling mark, most often found at crossovers.
Passing that point will mean you will be foul of tram wanting to crossover.

* One Half Width Yellow Line - Stopping mark for crossovers for rigid trams
(if you stop at the yellow line it means you have cleared the points and can
drive back over the crossover).

* Two Half Width Yellow Lines - Same again, but for articulated trams.

* One Full Width White Line - Approaching facing points

* Yellow Triangles - Cut off point for trams with pantograph at leading end.

* Yellow Circles - Cut off point for trams with pantograph at trailing end,
AND pole trams.

* White Circles - Sensor area for automatic points.
