JoAnna:

I think he was there to watch over Harry, since Dumbledore & Co. 
knew there was a good chance that Dementors would be searching the 
train, and that they might strongly affect Harry considering the 
horrors in his past.  They might also have wanted a teacher there 
(especially a good DADA teacher) just in case Sirius decided to do 
something stupid and sneak onto the train.
