History of the NSWGR D57

The fifth episode of the second season of my History series is here and this one is about an Colossal Aussie monster, the New South Wales Government Railways (NSWGR) D57 4-8-2 'Mountain' type steam locomotive aka 'Chuckling Charles' (because of their distinctive exhaust beat) or 'Lazy Lizzies' (Because of their immense strength and ability to just stroll away with any train given to them).

My great uncle was one of the designers of this train

Good but pleae be careful Al the 57s were superheated, and that device on the right hand side of the smokebox is the compound air compressor. :-)

I seem to remember a visit to Valley Heights, 5711 was on the shed, alas the firebox mud ring near the washout plug had rusted out completely. At least we have one as a static display.

I don't know what 296 sq ft is, but the grate area of the D57's was 65 sq ft (plenty big enough to need a mechanical stoker. The grate area is the bottom surface of the firebox, ie the bit that actually has coal on it. 296 might be the total heating area of the box, which is all the other sides and top surfaces combined, where it's in contact with the boiler water and can heat it.

It’d be nice to see 5711 run again, someday..

I would love to hear it as I'm a huge fan of Gresleys 3 cylinder engines.
The conjugation of the inside cylinder gave them a wonderful lopsided but syncopated sound

[@dat581]

The most powerful steam locomotive in Australia in terms of tractive effort.

70 years later in Victoria Australia, we’re still morning to loss of the 4 S class locomotives. Gone to soon.🇦🇺

[@TSRFilms1014]

They'll be still in the hearts of the rail fans of the southern Cross 🇦🇺

[@gibbsey9579]

Don't forget "Heavy Harry".

[@TSRFilms1014]

I do plan on making a History Video of that Engine

[@dunxy]

It was criminal they didn't save one :( They were all very tired when scrapped and at the time i guess nobody gave and f's. It did (iirc) prompt some people (Gerald Dee, again iirc he kept moving x36 to the rear of death row when it got to the front!) to make an effort and save other locos we thankfully still have. I was not there, but these are things i heard from people who were many years ago.

[@Steven_Rowe]

Superheaters don't feed exhaust steam back into the boiler, that is a condenser .superheaters take the wet steam from the boiler and further increase the temperature of the steam before it is fed into the steam chest

[@jonathanj8303]

And the thing next to the smoke box is a compound air pump for the brakes.

[@Steven_Rowe]

@@jonathanj8303 they are Westinghouse pumps as George Westinghouse invented invented the train airframe system.

5711 wasn't towed to Valley Heights by 3801 it was towed by S312 and a 442 class on a transfer run back in 2009

[@TSRFilms1014]

Thanks for the info

[@FlyingScotsmanAnimate2010]

thank you for pointing out an era.3801 couldn't have been towed 5711 as it last ran in 2007.

[@user-gz6hn1kb4y]

were they 3"6" or 4'8"?

[@TSRFilms1014]

4'8.5" aka standard gauge

[@user-gz6hn1kb4y]

@@TSRFilms1014 thank you. GL Garrett's in South Africa had 78000 lbs pulling power on 3'6" gauge

[@TSRFilms1014]

Well you can't really compare a D57 to a Garrett because it's one set of cylinders versus two so of course it's going to be stronger as a Garrett is two engines in one

[@user-gz6hn1kb4y]

@@TSRFilms1014 I know. just mentioning it for interest sake. axle load lot lower as well.
a 4'8.5" Garret design on that axle load cld hve easily handle 100,000 lbs, if not more, on wider variety of sections in Australia
