Not too well was my recollection. When I went through the school at Werris Creek 8650 was parked there and I recall we were told it tended to have a pitching moment about the center bogie that made it downright unpopular with crews. Happy to be corrected on that though, it's been many a year.

IIRC, 8650 spent a majority of its service life, particularly towards the end working in or around Lithgow. Zig Zag bank engine? Not venturing far from and in close proximity to the LMC.

Vicsig says they are all owned by the Dorrigo Museum and stored at West Tamworth.

It also suffered the fate of many 'one off' prototypes - long periods of time out of service waiting for repairs as the maintenance people didn't have the parts in stock and had to wait for parts and every thing took many times longer to do due to the fitters being unfamiliar with the mechanical layout.

8650 was really a demonstrator unit for QR. It proved Comeng could build what became the 3100 class.
Why the NSWGR accepted what was basically a prototype for Queensland I don't know. Presumably the 'price was right' at the time.

Wikipedia  says that the wheel arrangement on Tri Bo locos "requires either an articulated frame (becoming a Bo+Bo+Bo arrangement) or else significant side play on the center bogie". Did 8650 meet either of these criteria?

8650 and all 288 Tri-Bo electrics built for operation in Queensland have lateral movement in the centre bogie. The arrangement has been quite successful, generally providing better riding characteristics than similar Co-Co locomotives. The Queensland variants are capable of negotiating curves down to 80m radius.

Ask the kiwis, from memory all North Island Main Trunk locos are tribo and they had some very long sharp curves
