Sydney Trains weighs carriages to estimate crowds

Cyclists often have difficulty finding enough space on crowded train carriages. In an Australian first, Sydney commuters can choose the right train carriage based on real-time train occupancy data. Using the average weight of a NSW train passenger, we can now determine the occupancy of each carriage as the train doors close.  This information is displayed on the platform departure boards as well as several apps including TripView and Opal travel. The information will be available for more than 600,000 customer trips on Waratah trains every day. More info at
