Do this (https://estore.bachmanntrains.com/index.php?main_page=product_info&products_id=12797) and this (https://estore.bachmanntrains.com/index.php?main_page=product_info&cPath=68_789_697&products_id=13237) both have the speaker assembly installed? I know this (https://estore.bachmanntrains.com/index.php?main_page=product_info&cPath=68_789_697&products_id=10440) does not have a speaker installed since it says so on the webpage, but does this (https://estore.bachmanntrains.com/index.php?main_page=product_info&cPath=68_789_697&products_id=13275) have the speaker assembly installed?
I say "no speaker" I believe there is a note saying "Speaker not included" on one of the models..
