 Yes, I was quite surprised to see that. I had
 imagined some sort of dc rail, modulated with
 an mf two-tone (or something). Using a full
 bipolar switching scheme seems a hard way to
 go about it.

 However it seems that the model railway market
 is all going DCC, so that's the way my pal will
 have to go as well.
