I saw a news photo today that the pedestrian button at a road intersection no longer needed to be pressed. The system would assume there are pedestrians waiting to cross on every phase. A question comes into mind, can the doors on Xtrapolis and Siemens trains be programmed so that they all open on release? It would minimize cross contamination during the COVID 19.
Of course there are ways around it, but with those two train types the doors open and close both by electric motors. I wouldn't imagine it too difficult to change the wiring to make the trains safer to use at the moment.The doors are that way so as to keep the carriage either hot or cold and not over work the environmental system. Do you really think that Public Transport will be running next week?

I think majority of Sydney trains still do this but it puts a huge strain on the air-conditioning/heating systems of the train because the carriage gets fully ventilated at every single stop.That was a major issue with the 4D as well (and B2 trams - probably not an issue with Z/A class as the driver-only AC wouldn't spread that far, although I have cooled an empty A before (as in, 26°C outside, like a fridge inside) using the driver aircon, all windows closed and the interior vents behind each cab pointing to the floor - they're useless if they're pointing straight into the PIDs). The doors opened and closed automatically, but they couldn't close by themselves as there is no way for passengers to open them afterwards due to the lack of door handles. The inter-carriage doors were also automatic, but you had to pull the handle to get them to open (they closed automatically). Also, people could get stuck in the train back in the days of 1-carriage operation in the late 90s when the 4D was used at night (which was extremely rare), as disabling the carriages also disabled the door mechs including the ones between the carriages! Cue panic at Ringwood East one night when exactly that happened after the Lilydale train was boarded at Ringwood followed by the driver killing the lights in the back 3 carriages after the train left the platform! The train didn't become unlocked until Croydon; my guess is either someone on the platform saw the problem, or maybe the people in the lit carriage saw through the door.
If you're paranoid then use a pen or similar object to press the button.
