Beach's Pneumatic Subway Map

I have seen quite a few subway maps on
But I haven’t seen any based on the abandoned Pneumatic Transit.
I’m currently working on a sort of schematic of the whole system, if anyone wants to make it into a map.

Possible Features?:

Working shuttle train (or just docked at either stations, or stuck in middle of tunnel)
Accessible stations, and small street block above-ground.
Operable lights ???
All or most rooms accessible.
ambient sounds.

Great idea.
