What is the advantage to air-operated pointwork? I have heard of it before, but have always thought it sounded a bit "Rube Goldberg" if you don't mind me saying so. Although I must admit I can see it being more weather-resistant than electrics would be.

No electricity involved and the parts are standard industrial items, so it's robust, reliable, easy to install and suitable for remote operation over long distances.

Assuming no leaks, it only uses air when a turnout is changed, so it doesn't really need a compressor. I know someone who powers his with a garden sprayer.

It's getting harder for me to access some of the manual turnouts on my track and I'm considering installing remote control on the more remote turnouts on my track. Given the climate and wildlife around here, I wouldn't use electrics out in the garden on a bet. This years capital expenditure program may be a pneumatic turnout control system, instead of yet another loco chassis kit.......

Regards,
Graeme
