Railroad doors again

[Amy Z]

Reading the last train scene in GoF, it seems almost certain that 
there is no door between the compartment and the platform.  The 
Weasleys et al. drag Crabbe, Goyle, and Malfoy out into the corridor; 
then, at the end of the journey, they step out over them with their 
trunks.  The pleasure of another opportunity to step on C, G, & M 
notwithstanding, it seems unlikely that they would struggle out 
through the jammed corridor if they could just go out from the 
compartment to the platform directly.

What do you think?
