By implementing the multi-station concept it is now possible to control an entire railway line from a central post with one interlocking, making it possible to make changes to single station layouts without having to reconfigure and retest the entire system.
Unlike the old single-station concept the multi-approach allows each signalling device to be configured as if it were physically connected with a specific station.
This brings with it enormous advantages:
Additional stations can be added when needed, making it easier to carry out a staging approach without having to create a blockade and closing down lines for long periods.
» Significant reduction in the amount of testing: only the added parts of the system need to be verified and tested.
» Reduction in hardware.
» Changes to the system have almost no impact since the interlocking is data driven.
