This request for information comes from another group:

Just a question I have been asked.

Do Melbourne Trams have dataloggers and are they used to provide any information when incidents occur?

I note that there are over 1500 incidents per year on the Melbourne tram network.

I know the E's have cameras that can record what's in front of the tram, but don't know if they are 'always on' or turned on by the driver.
Yarra have published video of dangerous behaviour, so I assume there are some recordings.

Can anyone help with more info?
