02-Jun-2021: C2.5123 arrived southbound at same time as 6096 departed: as the doors opened, I looked in and saw that the front door opposite said "door not in use". As the tram departed I noted that the rear left door had both the reflector tape and the "Wear Masks" sticker on the door (as per Mal Rowe's photo at https://tdu.to/i/78158).
