The Tri-Bo is mostly a narrow gauge contraption.
A number were built for Japan and also Kiwiland for the 3 foot 6 inch.
The advantage of a tri-bo over a standard Co-Co being that flange wear should be reduced.
The middle bogie is normally floating.
The QR electric locos are tri-bos, again for 3 foot six inch.
With almost constant curves on the NSW Blue Mountains, it was believed that the tri-bo design would provide for less flange wear and wheel creep.
But, I can attest that 8650 did yaw and sway all over the place.
Quick give me the sea sick pills.
It was never adjudicated as to whether the tri-bo design performed any better.
Sadly, as with most of our once magnificent electric loco fleet, 8650 is shoved out at Broken Hill rusting to the rails.
Steve.
