ATLAS™ 200 is a radio based train control system which can
be used as an overlay on an underlying signaling system with fixed
block operation. It incorporates ALSTOM's ICONIS™ control centre,
SMARTLOCK™ interlocking and SMARTWAY™ conventional signaling
products. Movement authorities are generated trackside and are transmitted
to the train via GSM-R. Eurobalises are used as spot transmission
devices mainly for location referencing.

GSM-R is a 4 MHz frequency band for uplink and downlink radio communications
specific to the railway industry. It provides interoperability between
railway networks, safety and high availability. The EIRENE and MORANE
projects were set up to specify, develop, test and validate prototypes
of the new radio system. The applications identified by the EIRENE/MORANE
projects include:
| |
Controller-Driver
Operational Communications |
|
Automatic
Train Control |
|
Shunting |
|
Remote
Control |
|
Emergency
Area Broadcast |
|
Train
Support Communications |
|
Local
Communications at Stations and Depots |
|
Passengers
Services
|
The benefits
to the railway operators include interoperability, increased operational
efficiency and reduced operational costs. GSM-R has already been
chosen in Sweden, Germany, France, Switzerland and UK on the West
Coast Main Line.
