In 2017 the public voted on a short-list of 17 to name the six TBMs. They were named after inspirational women with a connection to the area where each individual machine started its journey. One began tunnelling from Fulham in 2018 and was named after Rachel Parsons, an engineer and advocate for women's employment rights, who set up the first women-only engineering company in Fulham. The others were cryobiologist Audrey ‘Ursula’ Smith and suffragist Millicent Fawcett for the Central area and suffragist Charlotte Despard for the Frogmore Connection Tunnel from Wandsworth to Fulham. The TBM that would tunnel the east section from Bermondsey was named after doctor Selina Fox who set up Bermondsey Medical Mission for Southwark's poor and disadvantaged residents. The machine for the Greenwich Connection Tunnel was named after Annie Scott Dill Russell, the first female scientist to work at the Greenwich Observatory.
