Outer Melbourne

Postby martink » Sat Jun 22, 2019 7:47 am

My second linear motor layout is now taking shape. This is another small Aussie layout, a 48" x 17" model in T scale (1:450) of a typical but fictitious location on the outer edge of the Melbourne suburban network. Quite a few lines around Melbourne drop down to single track for their last station or two before the terminus. The setting is the 1970s / early 1980s, and will feature electric multiple unit stock from that period, all 3D printed.

The track plan is a simple stretched oval, which will mainly run as a point-to-point shuttle. The rear half of the oval is concealed behind the backscene. Having a continuous run helps during testing, and will allow a great deal of operating flexibility. As usual, the layout will be fully automated, with up to 4 trains running in a semi-random sequence.

The layout will also feature a working two-lane road system, and a fully functional level crossing. Road traffic will stop and give way to the trains.

As with Monbulk Creek, the linear motor system is my own implementation of a product from IDL Motors.

The heavy construction work is almost done, just needing me to fit the magnetic sensors under the tracks before permanently fixing the road in place. Basic testing of each track loop is complete, and the next couple of weeks will be devoted to the electronics and software needed for the full bag of tricks.

Looking forward to seeing this, Martin. What scale will it be?

Doh, sorry, just seen that it's 1/450th scale. Have you made the motors smaller than for Monbulk Creek?

Uhh, the track IS the motor, so it is the same design as Monbulk Creek. The only difference is that I am using 120mm/45-degree curves instead of 160/30. 1:450 is my default working scale for this technique. The reason I changed up to 1:350 for the last one was the short narrow-gauge coaches, which have to be at least 24mm long (including the inter-vehicle gap). Sticking with T also means that I can use Eishindo car and truck bodies for most of the road vehicles, rather than having to make my own. That said, I may do a future one in 1:600 for really long trains.

While acquiring all the bits for the electronics, I have started work on the trains. Here is a first build of a Victorian Railways "Tait" suburban rake, in service from 1919 to 1984. I'll see how the windows look when simply painted, and then go to paper overlays or DIY decals if necessary.

I've been making steady progress on the electronics, which is now finally complete. Built, tested, and installed. The support wiring (power supply, controls, etc) is also done. The next step is to upgrade the simple test software I have been using to something that can bring the layout to life. I'll see about making a short under-construction video when it gets to that stage.

A working version of the software came together much faster than expected. This simple version only handles 1 train and 5 road vehicles in each direction (instead of the planned 4 and 10), but it proves that everything works as a complete system.

The trains are now taking shape, with the first basically finished and the rest not far behind. The pantograph is just sitting there for now.
