T Gauge Linear Motor Points/Switches and Automated Shunting
 
This video shows a small test track, demonstrating how part of my next linear motor layout will operate. It will be of a UK prototype, a minor 1930s GWR station, modelled in 1:480 scale (about 7% smaller than normal T Gauge).

The is a simplified and scripted version of the planned operating pattern of part of this layout, with automated shunting of UK-style 4-wheel wagons (each 12mm long!). The trains are just rough test builds for the moment. The full layout will be around 6' in length instead of the test track's 2', so will be able to handle (and shunt) full-length 40- or 50-wagon trains.

that's too small for me, eyes are not good enough anymore :)

Yep, super small, compared to that pencil. A 4x8 layout would be gigantic for those little guys.

Man, I can already hear John about how tight that is to get his Super Chuffer installed!! :)

FWIW, 6' x 2' works out to be the equivalent of 33' x 11' in HO, or about half a mile, but even with a small country station I am still going to have to do some track rearrangement to fit it all in.

Also, sound is quite practical in this scale with a couple of speakers under the layout, since the controlling computer always knows exactly where each loco is and what it is doing. However, as an exhibition layout, it is probably best not to do that since it will either be inaudible over the crowd noise or so loud that the neighbours complain. The level/grade crossing on the previous layout has working bells, but during three days of exhibition running nobody noticed!

This is spectacular.

That's cool, I was waiting for the multiple cars to be shuttled on alternate tracks. :)

Did you make the track or buy it, if so where?

All DIY. I design the circuit boards at home, each consisting of several pieces of track and joiners, then have them manufactured in small hobbyist-sized batches by a standard commercial PCB manufacturer. It works out to about US$10 per metre of track, a third of which is the shipping cost!

Can we see some closeups of how the track is constructed?

I hear you with shipping costs! I just bought 20 53mm x 77mm PCB blanks, the cost was $3.30, and shipping was $16.81 from China!
