We followed a book called "Toilet Training in Less Than a Day", which is a book from the 70s, but very good, in my opinion. And truly does work. My mother actually did it with DD, when she was 25 months old. It does very much what it sounds like you are already doing (doll, etc), but in a concentrated way. Basically you set aside a morning with no interruptions and go for it.
What I really liked about it is that she is trained all at once. Not over the course of weeks/months, back and forth with accidents, etc. Not that we never had an accident, but very few, much less than I hear from other parents who are following the tradional method of training over a long course of time. I think that the child is also happier this way because they are capable right away, and they can't like accidents much either?!? Another bonus is that this method teaches the child how to do it all by themselves, as it they have to go, they go by themselves.
You would probably have to do a search online, if you are interested in the book, because it is most likely out of print, although I can't think why. I think that it is so awesome!
