Line ring-fencing mode

Cantonment mode on the lines of the Réseau Ferré National.

The ring-fencing mode shall indicate the signalling system put in place to ensure the spacing of trains running in the same direction.

On the line, the ring-fencing method corresponds to that described in the technical information, to the average KP if the change is not made in exactly the same place for each track, without taking into account the interruptions of the ring-fencing at the crossing of certain stations, if this ring-fencing exists on either side of these stations.

The different types of ring-fencing are:

• Automatic blocks (BAL and BAPR)
• Manual blocks (BM)
• Telephone cantonments (CAPI and CT)
• Track-to-machine transmissions (TVM)
• ETCS
• Other
