Parts for 900's are not that hard to get, you can get complete motors for power generation etc from Blackstone, which was a part of the company, I think Paxman own them now, the original EE parts may not be available but those Blackstone or whatever it is offered as now certainly is.
The only reason AN scrapped them was because of the MU incompatibility, the locos were not that powerful by current standards at the time and the fact that the main wiring was shot, too expensive to repair, for too little work! They were like a car, it gets to a point where you have to make a decision to either repair the existing car or get a new one to replace it.

Forgive my lack of knowledge on Locomotive electrics, but can someone let me know what the major reason for the MU incompatibility was.
I have heard that other locos where at one time incompatible, but were modified to make them compatable.
Obviously there must be a standard circuitry used these days.

The main reason why EEs aren't compatible with other American locos is that the various American makes operate to an MU voltage of 72 volts and the standard 21 pin plug where as EE MU equipment operates to a voltage of 110 volts as well as a different MU jumper plug. What doesn't exactly help is the 900 class notch system with 10 notches rather then 8.
EE locos have been able to run with American make locomotives but after a lot of part substitution of components. Maybe one of our Tasmanian collegues can help out in what was actually done since their one off ZR and ZP classes have been made American loco MU compatible.

Thanks Will, I know the different voltages and pin configuration differences could be overcome, but 10 v 8 notch controls is a different kettle of fish

Don't forget the MKAs as well. AFAIK, only thing that was done to them was rewired to the American standard. Also, all have desktop control, only ZR2101 is different with its brakes, still has its Westinghouse 26L brakes.

So I hear that 621's long awaited return to service has been somewhat curtailed...

Yep, I've heard that there are 2 crown stays broken. One on top of the boiler and one on the side of the boiler.

Why would only two broken stays stop the loco from entering service?

The head of one of the stays was also weeping.

After watching a video on another site we are lucky it did not clean up another car, these morons stopped at the crossing, then as the train was approaching drove across in front of it. More guts than brains if you ask me!

Because the 2 stays are pissing out water, not just a small trickle like most people think they are.

Interesting. Time for some new stays then - or/and an inspection of thickness of the boiler platework in that area.
