That's a huge garratt engine!  What is it?  (2-10-4)(4-10-2)?

Hi James and all,
It is a 4-8-4+4-8-4 locomotive. The + signifies articulation with 2 separate engine units spanned by the boiler that can pivot on each engine unit, as compared to the Big Boy's designation of 4-8-8-4, with a pivoting leading engine unit and the rear engine unit fixed to the locomotive frames.

I hope that this helps clear things up for you,

An excellent looking refurb/rebuild (?); all credit to the ACT volunteers. Built to last by Beyer Peacock at Gorton.

Si: gunned concrete also known as Spraycrete here in Pommieland, but more likely here to be seen on road rather than railway cuttings. We looked at it for the dodgy part of our mine shaft but decided to do the job properly using poured reinforced concrete (no offence to Aussie PW engineers).

Note to U.S. "chimney first" loco engineers : imagine backing THAT up to a rake of passenger cars then setting off on the main line, trying to see the road ahead.

I want to drive it !!

Regards,   Michael

Thanks for clearing that up John, it's such a big loco it was hard to count the wheels in the photos.  I'm actually surprised that engine doesn't hold the world record for largest, that Garratt has to rival the size of a big boy.

Michael,

Try backing this one up (though the forward view is nice):

A cab-forward is in reverse when going forward and when going the other way, it is in forward gear. Confusing -so what does backing mean?

Proceeding tender first - "2 cars to go, 1 car to go, 1/2 car to go, ease up dead slow, THUMP, you're there"

Hi James and all,
yes the NSWGR AD60 class is the biggest Garratt design ever built in terms of dimensions. in terms of engine-unit wheelbase, the NSWGR Garratt beats the US stuff at 103' versus less than 90' for all of the UP Big Boy, C&0 Allegeny, DM&IR Yellowstone locomotives, however once length of the tender is added, then all these US locomotives are longer than 130' overall length.

I hope that this helps,

@oz
when shunting with the FR Fairlies, it was easy - just go chimney first....
