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.
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.
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
Most condensers are used on compound locomotives, where a larger front pair of cylinders can use the low pressure steam before exhausting it out the stack.
@ThunderboltSirenStudios that is true , also if you look at US compound Mallets you can see the difference in the two engines, one has larger cylinders
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.
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
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
@@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
As soon as he pronounced Wallerawang wrong and the loco number five seven one one instead of fifty seven eleven I knew he was from the UK. Please don't rely on the internet for info on our steam locos as much of it is incorrect. It's the same as a dinky die Aussie doing the history of the Southern's Merchant Navy class and getting much of it wrong. You really need to buy books on a loco class's history written by people who knew them inside out. Doing loco class history of engines from around the world and not being from those countries really is treading on shaky ground. I however applaud your attempt but you REALLY need to know you subject material thoroughly before you do a video on it.
1. I do use a variety of sources including websites and digital copies of books (when I can find them) and whilst I would like to buy books on foreign locomotives/railways, they can often be expensive to buy or ship over to the uk. 2. I am actually from Australia, it's just I've lost my accent as I only lived there until I was 8 and never fully developed my aussie accent. 3. However, I do get your point about misinformation being around and do try my best to cut out any incorrect pieces of history from the scripts before I finalise them but there are undoubtedly facts I've gotten wrong in my earlier videos that I am grateful for corrections on by people in the comments.

What a great little video thanks for the memories we had 5711at Enfield in 3 shed this loco should be restored
It's a shame she isn't restored but at least she's preserved in somewhat decent condition
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. :-)
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
And the thing next to the smoke box is a compound air pump for the brakes.
@@jonathanj8303 they are Westinghouse pumps as George Westinghouse invented invented the train airframe system.

70 years later in Victoria Australia, we’re still morning to loss of the 4 S class locomotives. Gone to soon.🇦🇺
They'll be still in the hearts of the rail fans of the southern Cross 🇦🇺
Don't forget "Heavy Harry".
I do plan on making a History Video of that Engine

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

The most powerful steam locomotive in Australia in terms of tractive effort.
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
Thanks for the info
thank you for pointing out an era.3801 couldn't have been towed 5711 as it last ran in 2007.
were they 3"6" or 4'8"?
4'8.5" aka standard gauge
@@TSRFilms1014 thank you. GL Garrett's in South Africa had 78000 lbs pulling power on 3'6" gauge
