\language "english" is preferred over \include "english.ly".  The latter 
is a vestige of older LilyPond versions where the \language command did 
not exist, and the "english.ly" include files did more stuff.  Now, 
"english.ly" is just a \version and \language statement.

I think you can get away with \defineBarLine being inside music, but it 
would probably be poor practice.  It is better to place all definition 
(or definition-type things) at the top-level.  The only exceptions are 
things that specifically require scope, like \paper variables.

As to why the bar line did not appear in your snippet, you redefined the 
bar twice in the same moment.  Only use \bar once.  In this case you 
would place the \bar command at the end of the alternative or at the 
beginning of the "Trio" section.  As to which, that is probably personal 
taste.
