The map at the top of the page shows two other much discussed topics.

At the bottom of the map, the route of the Waterloo and City line, and
in the middle the "Post Office" after which today's St Paul's station
was originally named. The station building itself is shown to the north
of Newgate St; today probably in the middle of a traffic island next to
the entrance to the BT HQ.

Most interesting. But what is the line in a tunnel that appears to lead
from Holdborn Viaduct Low-level station under Smithfields meat market
to Aldersgate (now Barbican) station?
