what is the highest station that I can get dropped off by bus or car or train?

If road conditions allow, you can get as far as the 5th Station by car. But the road could as well be completely closed, in which case you would have to start from the base. There is no public transportation.

assuming moderate conditions how many hours to the top?

Depending on whether you can make it as far as the 5th Station or not, the altitude difference is about 1500 to 2500 meters (one way) in the ice. I hope you know how many hours of hiking this translates to. In moderate conditions, I am pretty sure it takes 24 hours or more for the round trip from the 5th Station. Or about three days from the base.

and any avalanche dangers or routefinding difficulties?

Yes.

From your questions, it is obvious that you need to do a lot more serious research in case you really want to climb to the summit of Mount Fuji in winter.
