I regularly cruse the local thrift store looking for 12V DC power supplies. Here in the USA bigger ones that put out 1-5 amps can be had for $2 - $5. I would assume a similar used market there.
Is there only 1 output. Usually there are two. A set for 16VAC and another for Variable DC. I don’t understand how there could be a direction switch if there is no DC output. AC doesn’t switch directions except for 60 times a second (or I guess 50 times a second down under 
)
Not unless you are planning on turning 800 lb. gorilla’s on that table. 6 to 12 Amps is enough to run a whole layout. I am guessing the turnout motor will not need more than 1/2 amp. I’ve got one in a box sitting around here somewhere I should probably get it out and test it, but if it is more than 1/2 I would be very surprised.
Finally, I don’t know where all this talk about building your own power supply originated, but I recommend NO. First. what I’ve seem is talking about North American standards for wiring (except for gregc who at least mentions 220V)… The USA only runs a 120V line voltage. Fairly dangerous but a good shock is not necessarily deadly. I’ve been zapped more times than I can count. In Australia your voltage is almost twice that. Very dangerous. I am fairly certain Australia is going to have different standards for grounding, common, and hot wires and even the color of wires. So the reality we know and talk about day-to-day may not be your reality in Australia or anyone else’s reading this from a country other than the US and Canada.
Tomcat,
Well you can throw all my advice,out the window,I totally forgot,you’re from,down under…
All my power supplies,I have built myself for my layout,not once got zapped,including rewiring my house,and putting in a 250amp service,but then again,I was a licensed Electrician. But what do I know.
Cheers,
Frank
have you considered a momentary DPDT switch? momentary means it only applies power when you hold the switch in either the forward or reverse direction.
That’s the best option for me at the moment I think,
I still have to find a power supply
Tomcat,
Do you know any good Electricians,that can change one of your 220 outlets,to a 110v,20amp.outlet? He justs need to take one leg of the 220, along with the neutral…He can put it in a metal fused,knife switch box.
Cheers,
Frank
That’s probbaly not allowed by code.
Shouldn’t be too hard to find a suitable power supply pre-made. It’s not an uncommon output voltage. Not sure what all the fuss is about.

Amen to that. [bow]
12V DC is the maximum voltage that should be applied to the TT motor.
just because it says 12V doesn’t mean you can’t use something lower, 6V DC.
The TT will move slower, more realistically.
