Well, I sent them an email and we'll see what comes up.
Running through their "catalog" I did see that they offered a complete system for AC operated trains. I have no idea of the cost, but I suspect that will be coming. I also asked them about them about the chopped sine wave thing and suggested that they recommend a good power source. I don't know a chopped sine wave from a sinus allergy.
I'll keep you all posted.
Just as an aside, keeping in mind that I know nothing about this subject, they did offer some really intriguing products related to automatic operation with two trains on one track and running trolleys. I plan to do a little more looking on their site.
