twin coil switch machine limited to one activation per minute

Gentlemen,

I'm working on a rather large layout. I have two switches that I would like to run "automatic" non derailing using twin coil switch machines. Is it a problem to allow the wheels of a long train to constantly activate that coil in that manner? If so, does anyone make a unit that will allow that switch to activate say, once per minute (while allowing for a manual override momentary switch)? Keep in mind that I am an art and scenery guy. So if you send me some circuit to build...well...

I had several capacitor discharge units that were supposed to work for this. But these did nothing to control the amount of times the switch activated and when it did, it seemed too powerful. I set these units aside as dangerous as they created arc marks on the truck I was using to test with.

Thanks,

Troy
