SIRIUS, the Invensys Rail Dimetronic’s CBTC (Communications Based Train Control) is an Automatic Train Operation system which presents the advantage of reducing the interval between trains, among others, thus increasing the transport capacity of the line. Users of line 7B can already experience the advantages derived from the implementation of this system.

SIRIUS implementation in line 7B is the result of the collaboration between Madrid Metro and Invensys Rail Dimetronic for the application of CBTC solutions in existing lines that demand a higher transport capacity.

In case of an eventual failure, SIRIUS is able to continue operating thanks to its exclusive way of support based on a "speed codes" ATP system, which allows maintaining a safe train circulation, using the existing line infrastructure.
