Ticket machines on the London Underground (LU) have been upgraded to operate in 17 different languages.
Some of the touch-screen machines were already available in six languages - English, French, German, Italian, Japanese and Spanish.
From Monday, all machines in every station will also have Arabic, Bengali, Chinese, Greek, Gujarati, Hindi, Urdu, Polish, Punjabi, Tamil, and Turkish.
More than 300 languages are spoken in total in London.
Kulveer Ranger, Transport Director to the Mayor of London, said: "Boosting the number of languages on our ticket machines is just another step in making life easier for those who live in, or travel through, the capital.
He said it would give many people added confidence, help maintain London as a city that supports its cultural diversity and would also improve tourists' visits to the city.
LU is undertaking a major programme of renewal as part of Transport for London's Investment Programme.
