The condensing didn't work so well once the Circle Line (then called the
Inner Circle) was opened in 1884, because there was no chance to stop
the trains and drain off the hot water. Nevertheless, steam working
continued until 1905.

Regular steam hauled freight services using condensing pannier tanks
continued on the H&C/Circle line between Paddington and Smithfield
(Farringdon) until the 1960s. It was quite a strange experience waiting at
say Great Portland St (Metropolitan) on a Saturday morning and seeing a
pannier and assorted freight wagons trundle through.
