During my travels on the Cranbourne line on Wednesday, I sighted what I believe to be E.6004 getting ready to leave its shed on the end of the Bombadier test track for a run up and down the track. No photos though - it's a bit hit and miss as to when you see an E class out and about and the trains run very fast on that line.
During my travels on various trams this afternoon, I saw E.6003 on High Street, Kew outside the side entrance to Kew Tram Depot. I don't know where it had been or where it was going. It was about 3pm when I passed it.
I went on a ride at lunchtime and it went very well. 6001 and 6002 running together (one appeared to be on a scheduled trip and the other wasn'tn - running one after the other). Lots of passengers taking photos (eg. non-gunzels). Tram was quiet and very large. A few people tried to board at the drivers door - so that might require some signage. I've been on the similar design in Porto, but the Melbourne design is more open and much nicer looking. It was all deliciously boring - which is exactly what you want. It appeared to work and work well. Well done to Yarra.
