The internet, as 1887 would have built it
Brass tubes instead of fibre, steam instead of electrons, and a clerk with a ledger instead of a router. Below is a working model of our small exchange in Paris, running as you read.

How a capsule travels
Sealed
Your message is cut into pages, and every page goes into a capsule of its own.
Addressed
Each capsule gets a brass address plate, so it can find the way without the others.
Dispatched
Steam pushes it down whichever line happens to be free at that moment.
Signed for
The far station sends back a pulse for every capsule. Any that go missing are sent again.
Dispatch ledger
The latest capsules through the Paris exchange.
