Does anyone know where you can buy Twin Coil Switch Machines like N J International and KTO used to make?
If you are really into those old railbuster machines, you could make your own. Some years back MR had an article showing how to make the old twin coil switch machine. Good article, I made and used them on my home layout. I would suggest you not use them. They are tough on track and are difficult to keep aligned. The newer stall motor switch machines are far superior in every way in my opinion.
Steam, forever steam.

I agree with Tom. . . twin coil machines are are obsolete. The new stall motor machines are sweet; easy to install and zero maintenance.
NJ International twin coil switch machines are still available from Walthers. Check their Web site.
