Real-life train occupancy information will now be available to commuters through apps such as TripView, NextThere, AnyTrip, TripGo, and Opal Travel. 

The occupancy data will be determined through the average weight of a NSW train passenger in each carriage. 

Commuters will be able to access information for more than 600,000 trips in Waratah trains.

The Waratah-style trains service more than 54 per cent of all trips in Sydney Trains Network on popular lines such as the T1 North Shore, Northern & Western Line, T2 Inner West & Leppington Line, T3 Bankstown Line, T5 Cumberland Line, T8 Airport & Southern Line, and T7 Olympic Park Line on weekends. 

In addition, the NSW government has ordered 24 more new Waratah trains, which will be available on the tracks from late 2018. 

“Now train customers can see how full their train is before it arrives,” Premier Gladys Berejiklian said. 

“Transport is no longer just about infrastructure but also about embracing technology to provide the best services possible for our customers,” she added. 

Transport and Infrastructure Minister Andrew Constance said that this introduction will lead to easier commute, with less congestion. 

“For customers who commute home from Wynyard to Penrith, for example, getting a seat can be a major factor in deciding which carriage to board,” Mr Constance said.
