200011 – Balck – Interflow: An Alternative?

InterFlow is a communications based modular system that facilitates the control and
automation of freight and country railway systems to a level suited to each unique application
and customer demand.

The InterFlow concept is based on radio communication between the stationary control
system and the locomotives. The system provides in cab information to the train driver and
provides Automatic Train Protection. In case of driverless trains (in a mining application) the
system communicates directly with the ATOIATP equipment.

This results in a cost effective system with minimal wayside equipment, reducing the initial
investment cost as well as the operational maintenance. Apart from passive balises along the
track and object controllers at each point-machine, all system components are in the control
room or onboard the locomotives. Changes to the system are simplified as there is a
minimum of wayside plant.
