I've come across the notion that some of the earlier development ideas
proposed running the system running through the small side tunnels (or
at least one of them) which provide access to the central terminal area.

It's much more than that - they've used the promise of a large pod
installation through the old cab tunnels to justify various expansion
plans within the T123 complex.

The T5 installation is supposed to be the pilot.
