Alstom to modernize the Mitry-Claye control unit with its
Smartlock system

In summer 2011, Alstom will deliver a new generation
Smartlock computerized control unit (PAI-NG), the second such
delivery under the framework contract signed by the two
companies in 2006.



The order is part of the project to improve rail services on
the northern part of RER Line B (Ile-de-France) carried out by
RFF, the SNCF and the STIF. The Mitry-Claye electromechanical
control unit will thus be replaced by Alstoms latest
computerized interlocking system. The Smartlock 400 range has a
powerful safety computer, which is capable of managing very
large stations. This new installation, which includes a
modification to the track at Mitry-Claye station, will improve
the operation and service quality of this strategic rail route,
which carries up to 40 trains per hour - almost one train every
90 seconds.



It will increase operating flexibility and efficiency in normal
and sub-optimal situations by computerizing and programming
some of the control unit commands.



Since 1997, Alstom has supplied 17 computerized control units
to RFF including that of Strasbourg in 2006, which is the
largest computerized control unit in Europe.
