The Baku subway is upgrading its infrastructure as part of the state programme on improving its material-technical base, Day.az cites a source in Bakmetropolitan.
Modernisation of the ventilation system at stations and in the tunnels is aimed at improving the microclimate.
The state programme on development of the capital's subway system involves updating the motor-rail transport, modernising dispatcher communications and radio links with the trains, purchase of maintenance vehicles, and washers for tunnels and machines.
In addition, new cable systems, alternative energy sources and a substation will be installed to provide uninterrupted electricity flow.
