Small Retaining Wall Build

 Back again!

When I first started drawing 3D signals that were available through my Shapeways Signals Branch shop the range was initially in the sintered nylon powder previously called White Strong and Flexible and now called Versatile Plastic by Shapeways. The signal detail parts were in Fine Detail Plastic. At the time I bought enough signals to signal my BYLONG layout. It was later that I redrew the signals for the Fine Detail Plastic and then Lost Wax Brass. So, I have been building my signals but upgrading them with fine ladders and wire handrails, etc. They don't look too bad at all, at least from a normal viewing distance.

I have been working on a triple bracket lower quadrant signal for my Wollar station yard on and off for some time in between making brass NSWGR signals for other modellers and I recently decided I had better finish it.



Here are some recent signals made from my range of locally produced lost wax brass signals.

Contact me by email at rpilgrim@bigpond.net.au if you wish to know more information about my range of signals or about ordering from my range, either signal kits or made up signals.

I cut off the existing crank-style mechanism and replaced it with a triple linear servo base as the under baseboard location of the signal was difficult to access. The linear servos were being driven by Tam Valley Singlet II servo boards that also have a DCC accessory decoder. The Singlet II boards were going to be mounted just under the front of the layout for easy access with one of the LEDs on each board being extended to the fascia. The reason for the visible LEDs was to show the position of the three arms as the actual signal could only be seen from the side. In doing this I also had to source some longer servo cables which I did through the Model Railroad Craftsman at Blacktown NSW.

Now, the location for the signal required the removal of some scenery from a low embankment in a box shape so I decided to draw up and 3D print a three-sided retaining wall made of sleepers and rail.

I had previously drawn a long retaining wall made of sleepers and rail for my layout so I modified that to suit.

Here is the retaining wall temporarily in place after trimming the scenery to size.

And here is the final placement of the retaining wall after painting the vertical rails with an old rust colour and using black powder on the grey plastic for the wood sleepers.

A nice afternoon's work I think.

The signal has had the throw of the signal arms adjusted and set by the Tam Valley Singlet II boards and it has been screwed in place. Unfortunately though as can be seen from the last photo above, I have to remove it and glue the large painted cast-iron brackets under the bracket platform, too excited to get it in place for sure.

Hi Ray. Thanks for your ongoing efforts with 3D printing the goodies for our layouts, now I need some Retaining Walls for some of my LQ Semaphores installations from your initial orders from Shapeways. Bye the way, the detail including the ladders/handrails is fantastic for me. I've built 35 including some Bracket and 2 triple Brackets and motorized 3/4s. With Occupancy Detection (now home made), I've achieved the operation I want, without a Signal Box Operator. Regards Marcus
