Greetings from the National Convention Centre in Canberra where the Australian Railway conference "AusRAIL 2012" is on today. The conference exhibition has spilled out of the exhibition hall into the foyer and upper levels. Heavy engineering companies from around the world are alongside Australian logistics and ICT. The exhibition is free and open to industry, academia and government until 3pm today. The next conference is November 2013 in Sydney.
