Whatever the reason, to me it seems daft to have built a train to large to
be able to run on any other tube line and can't even be rail hauled to its
depot. And then instead of using the tiny amount of extra space the larger
size has gained they waste it with thick walls and door pillars. Common
sense was in short supply when the 2009 trains were designed IMO.
