Remus on the Hogwarts express (better late than never?)

While rereading sections of PoA last night, a light bulb went on in 
my head.  Okay, it's a very dim bulb-I know this is several years 
after the fact.  I did try an archive search, with the usual results.

Remus was on the train because DD wanted him there, wasn't he?  It 
wasn't because he couldn't get there any other way or was too poor 
to own a broomstick or anything else.  DD suspected that there might 
be a dementor invasion, knowing as he does that the dementors don't 
respect boundaries very well.  Whether Remus was supposed to watch 
out for Harry in particular or to keep things under control in 
general, I don't know.  It's coincidence that HRH ended up in the 
same compartment with Remus.

Although I still don't buy Kneasy's theory that DD planted Remus at 
Hogwarts to draw Sirius out, I'm beginning to think that maybe that 
appointment had more than one reason.  DD might have wanted someone 
at Hogwarts who could provide advice and support for Harry if DD was 
otherwise occupied.  Remus and Harry were developing a trusting 
relationship throughout PoA; Had Snape not outed Remus, DD's plan 
would have worked.
