The first international market addressed by Intelligence on Wheels is Australia. This accounts for the fact that the RCAS approach is most feasible for the situation in Australia  with plenty of kilometers of track network which is extremely expensive to roll-out and maintain any traditional infrastructure-based safety technology.
Here the major advantage of RCAS of being independent on any element in the infrastructure (e.g. no network of base-stations required, no sensors and signalling along the track required etc.) is a major asset. Thus the presentation of the equipment of just the rolling stock was well received by the audience of the AusRAIL 2012, the Australian national major rail technology conference and exhibition.
