The Beijing Subway Co yesterday started rehabilitation on its stations that will allow passengers to use their mobile phones and shorten intervals between trains.

The building of barrier-free passages and the installation of Braille signage and new handrails at subway stations is expected to make using the subway more convenient for handicapped people, the company said.

Renovation on Lines 1 and 2, which were built in the 1960s, is in full swing, and is expected to be completed by April. When the work is finished, all of Beijing's subway lines will be covered by wireless telecommunications networks.
