A big thank you to @yarratrams who not only found the bag I left on a tram, but who were super supportive and got back to me within an hour with an update. Mark at Yarra Trams Lost Property, you made my day better. Thank you.
@ptv_official Can you do a call out to unlock the windows on the trams? No trains means we're packed in like sardines and the windows on my 75 tram are locked!
