According to Steamrail's Facebook page, A2 986 took a major step forward in it's restoration this week with the wheel set reunited with it's frame.

Won't be too long before she's back on track...

It's a shame she won't be standard guage so she can get further than Victoria!

I don't think the design allows for an A2 to be gauge converted, so it's a moot point.

Please keep it here anyway - look what happened to R766.

What has happened to R766 anyway? Not heard anything about it in a couple of years.

Back on topic though, it will be great to see an A2 steaming itself again.

No argument there. The A2 ( and particularly the Walschaert version ) was a classic loco.

Couldn't have said it better myself... these A2's sure are a nice lookin loco

Yep.  And any accreditation/test runs on the mainline will probably result in the most foam witnessed around Victoria's railway system since The Flying Scotsman was around...

Not really knowing much about this A2, will it be oil or coal fired? And if oil fired will it have the round tank or a square tank? (if a square design was ever used).

Cheers.

Coal fired

Both cylindrical and rectangular tanks were used on oil fired A2s. But 986 will be coal fired I believe. Seems odd to me but no doubt there are reasons.

A2 986 was oil fired with a cylindrical tank when it last ran, but it's been converted back to coal.  Cheaper to burn high quality coal than oil (even recycled sump oil).

Can't say I recall 986 ever having a square tanked tender?

The oil burners got square tanks when they were first converted (off the top of my head I think it was in the 40's). A number of A2's later recieved the ACN tender with the round tank. A2 986 was one of them.

Pretty sure your right James. The square tank was used so that if the trials of this type of firing failed it would be easy to convert the engine back to coal (the tank just slotted in the coal bunker). A2 996 had such a tank in it's tender (was removed by the Port of Echuca IIRC) and I'm pretty sure C10 in the ARHS Museum still has a square tank.

I noticed a video and some photos on FB of A2.986 running around the yard at Newport today under her own power.  

A "Huge Congratulations" to all who have contributed to achieving this incredible feat.  Can't wait to be a paying passenger when she's hauling tours.

I am old enough to have seen many A2's in service, including double heading on the Overland.  It will be very good to see another one in action again. Well done, Steamrail.

Just had a look at the photos amd to me something did not look right with the valve gear.

Compare the following photos:
https://www.flickr.com/photos/78379788@N06/17638552203/sizes/l taken on Saturday,

with this one http://www.victorianrailways.net/motive%20power/a2steam/a2steam1.html taken about 1960.

It appears the return cranks now "throw" the other way.

That would occur if the driving axle was rotated through 180 degrees in a horizontal plane.

That would reverse the normal settings of the valve gear, so the locomotive would go in the opposite direction for a given gear setting. This would only be a problem if you didn't know about it...

Or has it been converted from outside admission to inside admission?

It would need new cylinder and valve castings for that....

And better glands on the valve rods.....

This is just fantastic news, she really does look amazing. Massive credit is due to the crew at Newport that have manged to pull this off.

Not to jump the gun too much, but would this mean the A2 would be close to a test run out on the mainline? If not, what more needs to be done, is it just beuracratic red tape or some actual work still required to get her out of the yard? Again, I don't mean to come across as impatient, just curious to know a rough idea how much work is still to go.
