ATLAS™ 300 is a continuous speed supervision radio based train
control system with moving block operation. It is based on GSM-R
for the track to train communications and on Eurobalise as spot
transmission device, mainly for location referencing. The RBC provides
information to the trains and knows each train through its unique
identity.
Train location and train integrity supervision are performed by
the trackside RBC in cooperation with the train.
In the fixed block system, a section of the track is fixed by a
"block section" and generally only one train is allowed
on each block. In the moving block, an area is defined by the braking
distance and the length of the train. It moves with the train allowing
better use of the track with smaller headways.
