Well, That was quick.

It is that time of the year again, another year done and dusted, The layout underwent a fair bit of work, rewiring for DCC, building and street lighting, the Caulfield Exhibition, then the installation of the animated gates. Fun times all round.

So as per usual, and somewhat late this year, the time honoured Victoria Street Christmas Card.

 
 
The season brings its annual wishes and hazards, above all be safe, enjoy/endure your family, reflect on the year, and try not to eat or drink too much.

'Open Sesame'.........'creak, groan, clank'

Yes, I have done it! I have finally animated the crossing gates of Victoria Street. Another item has been ticked off the bucket list.

 
The finished product.
 
 
The gates are operated by a Tam Valley DCC servo decoder, the crossing lights are controlled by a six function decoder. The four crossing lights are LEDs mounted on the shafts of plastic provided by cotton buds, each LED has its own light feature, two are alternating strobe, one the Mars light function and the other the rotating beacon. This provides the prototypical mismatched sequence of rotating beacons that were installed at these crossings.
 
 Also the tram signals are operational, with a fibre optic thread running from LEDs using the other two functions (headlights). A LED is mounted on the facia in parallel of the tram signal to show its status.
 
An OFF/ON switch is fitted between the DCC bus and the servo decoder, plus the six function decoder in so to isolate the set up when running 'antique' DC rollingstock. 
 
 
 
Another dodgy video, but it works.

More on the Gates

Now the fun part of installing the mechanism/control for the gates to the module. Holes were drilled at the base of the pivot points of the base board when the module was built, in the hope at the time.

The servos are fitted on Brunel Hobby servo mounts in a way not envisaged by the designer, the servo is mounted upside and with the inner side of the mount missing to allow the sweep action of the servo crank. The pivot pin is made from copper wire soldered to a copper wire 'staple' that that is hot glued to the crank, the pins of the 'staple' lines up with the holes of the crank, and the pivot wire lines up with the centreline of the servo shaft. A clearance hole was drilled in each of the servo mounts for the pivot wire to protrude through.

 
One of the four servo assemblies.
 
 
The crossing gates are readily available, made by Peco, while British in origin, they have been kitbashed and details added to make them more like the older style gates that dotted the railway network prior to the more contemporary boom gates. These were drilled out with a pin vice with a 1mm drill bit, along the centre line of the hinge pin.

(The copper wire will 'give' in the event of impact,
the post is pressed fitted onto its base)

Work in progress
(the servos are pinned with thumbtacks until final positioning)
 
 
The front of the module will be replaced with a perpex window so to keep an eye of the inner workings.

"Open up the gates!"

One of my many projects on this layout was to somehow animate the gates of the crossing square of Victoria Street, I do now believe that I am a step closer to fulfilment.

I have glanced over the possibility of using servo motors in the past, but had no real idea how to make it all happen, today I stumbled across the dark arts of Tam Valley Depot being offered by Brunel Hobbies at the Croydon Model Railway exhibition.

After parting with/investing some cash, I came home with a servo decoder and four servos, in the process of cooking the Sunday roast, I nutted out the how to put it together, then program this collection of components, and made it work as a proof of concept.

Some happy snaps...
 
 Blu Tak is a wonderful product.
 
 
The entertaining part will be fitting it under the module
and making it work.
 
Behold the wonder of technology.............(and dodgy video)
 

 
some tweaking will be required, but that's where the fun is.

My cup runneth over again..

 As per usual at this time of year I have engineered a week off to co-inside with the Melbourne Cup Carnival, and as per usual there is a punch list of stuff to do around the house that not only would choke a brown dog, but also a thoroughbred.

 While I am permitted to wander down to Flemington (with the bride) to catch up with mates, sample a few beverages, and give money to bookies, the off days include a burden of tasks to be completed to the satisfaction of the minister of war and finance.

 So here is my homage to the spring race season, traffic mayhem, punters everywhere,  unpredictable weather and trams.

 
 
 



Planning is in progress for the extension....

Extending Services......?

While the layout 'works' at the moment, it does require a fair level of 'plonking' to rotate rollingstock at the fiddle yard end.  In reality the layout requires a depot, not a big one but one that would allow the stabling of trams and the ability to shuffle trams on certain roads to suit certain needs, without the issue of  'manhandling'.

I have cunningly devised a possible extension that may do this, first the original fiddle yard becomes another terminus, the space between the fiddle yard and the 'Railway station' becomes a chicane that allows the establishment of a small three road depot behind the 'new terminus'. (laughs manically while forming his fingers into a steeple like manner while chanting "Excellent, excellent")

This 'Chicane module' would offset the layout into the foreground, while freeing up space at the rear for the Depot.  The Chicane module therefore would be twice as deep as the other modules, but would free up some real estate for some residential development.


Now what would be the scene of the new terminus, another retail strip/beach type could work, but I was thinking more along the lines of an industrial setting. The inspiration for this terminus is the route 57 West Maribyrnong, which terminates at the Commonwealth of Australia/Defence Department Explosives Factory at West Maribyrnong, oddly enough.

This terminus features some open ballasted track, that once upon a time, had a siding for extra trams during shift changes at the factory, and then for quite a while did not see Saturday afternoon/Sunday services, which it lent itself for a great place for layovers for enthusiast's excursions. This ticks a few boxes for the scenario at the other end of Victoria St.

The Explosives Factory at Maribyrnong has been around for over a century, original making cordite, then moving onto TNT, then other stuff that could give you a nasty rash. The tramline was extended over the Maribyrnong River in 1941 as things were a little tense then that led to some urgent oil/petrol rationing, this tramline provided workers (mostly women) to service the war effort.

 
The inspiration...
An old photo of the West Maribyrnong terminus with siding,
 the explosives factory to the right, Cordite Road on the left,
 (note the single blade point for the siding)
 
The plan...
This is a rough draft, the fun part will be making it all fit.
 
 
Because a layout is never finished,

Service interuptions and some analogue running

It has been a month since Caulfield and I have done nothing since then, the layout has sat in the study as I left it when I came home on that Sunday night. The last weekend I started the getting 'the band back together', all that was needed, was a flick through of the October AMRM  to realise that I still have some work to do.

As part of the reinstatement of Victoria Street, the DC option has now been fully integrated, this now allows one tram at a time to be test ran to see if it should be fitted with DCC, and also gives those other pieces of rollingstock in my collection a chance to stretch their legs.

Since the conversion to DCC some two years ago, some trams and some new purchases have not the opportunity to get out of the display case and 'cut a notch'. Thus now introducing a rogues gallery of ring ins of my DC fleet......

 
A Walters Birney done up as MMTB X 217 with arse about doors
on a Tyco/Mantua Chassis.

 
A Tyco/Mantua tarted up as MMTB U 205
(Pretty much a dead ringer)
  
 
But wait, there's more waiting to become something else...
(and they all work!)

 
A Cooee Collectable Restaurant Tram with A Bachmann Brill Mechanism,
(this has a lot of potential with DCC/lights)
 
 
A Kochi 600 Hasagawa 1-80 kit with a Bachmann Brill Mechanism,
(The panto is pushing the body down at the No1 end,
another DCC candidate)

 
A Kato Hanover/Hiroshima Tram,
(Now this is a well built model)
 
 
A Double Truck Birney (Ken Kidder???)
This will need some work as it runs the old school
pick up from one side of one bogie, pick up from the other
side/ bogie, and it runs like a dog!
 
 
A Muni Boeing LRV by Mehano, this could have potential for DCC/Lights,
but could do with a better mechanism.
 
 
This is the RTR DC stock that has been waiting to have a crack, there are also some other projects/kits on the back burner waiting for their chance.
 
From under the wires and the smell of ozone of the rarely turned motor.
