Have my first Kato point for test and it works well using dc supply through DPDT switch and push button for temporary burst of current. Has anyoned tried operating point from 16v AC transformer using 'opposing' diodes and conventional passing contact awitch? I realise the output would be 25 cycles but wonder if the idea is practical.

I don't think they can be operated with 16v AC. I have found this controller that might work out cheaper than the Kato point motors as it will operate 25 points. The cost works out at about £25.00 depending on the exchange rate. http://www.rpc-electronics.com/mrr.php

Thank you Poliss, but I want to use transformer(s) and 'Passing Contact' switches that I already have for my 00 layout. The basic idea is to obtain a double source of DC curent, one side of the circuit being common to the point motors from one terminal of the transformer, the other having swiched polarity from the two 'polarity reversed' diode rectifiers connected to the other terminal of the transformer. In this way the circuits would be intermittent unsmoothed DC. at 25 cycles per sec but at opposite polarity at the passing contact switch, which feature is the essential requirement.
My post was to find out if anyone had tried this system or had a good CHEAP alternative method. (I've got to sell my 00 gear before I can splash out on 'n')

I know a friend who also uses kato track he uses an old nokia mobile phone charger to power his points. I haven't tried it myself but I have seen it working and it doesn't look to have had any problems
