I presume when the author writes "There is, sadly, no trace of any of
the stations that were built on the first Underground line..." that he
is referring only to the Baker St to Farringdon section and then only to
the station buildings, rather than the platform area.

Bayswater, and Gloucester Road station buildings are two that still
survive.
