my dad helped build harry. he was a riveter at newport workshops. later on he fired on harry. all the crews thought it was the best loco in victoria. as i said in the comments of your s class video, he described firing on the s class as "bloody hard work". but he said that the hardest he ever worked was on harry when the mechanical stoker broke down.

i know its impractical to restore such a big locomotive for Steamrail, but i wish it was running, a single engine with that much history in service, deserves to be well treated and celebrated on the mainlines, it could be driven at a fraction of its power for longevity and still easily make the grades.

The Gresley Conjugated Valve Gear used in the S class, while fine on paper, presents a number issues in practice. Aside from the high placement of the center cylinder in the casting (as shown at 6:03) causing premature failure due to heat from the boiler, but because the lever arms were attached to the front of the outside valve rods, as the engine heated up and expanded, the inside valve gear would thrown out of time. Not only that, but the long levers of the Gresley mechanism had a tendency to flex at high speed, causing the timing to be thrown out even more. The Henschel und Sohn valve gear used shorter, more rigid rocker arms to mitigate flexing, actuated from the rear of the outside valve rods to avoid the problems caused by their heat expansion. This new system had the benefit of allowing the middle cylinder to be further forward, driving the first axle instead of the second, and thus also allowing it to be positioned lower, away from the heat of the boiler. I suppose this is the difference between British engineering and German engineering.

A surpsing super highlight at 11:15 with the first film of H220 actually in motion and pulling a moving train. And in colour too. Even the late eighties V/Line offical Power Parade video was not able to supply any film of H220 in motion at all. Now i will supply a link to this to all my VR interested friends.

The H220 is definitely a very unique locomotive and it's also one of five three Cylindered steam locomotives to have operated in Victoria

Funny how this came out not long after I did my documentary on H220

I don't know where you got your information from but you have a lot of errors in your description. The radius of curves was not the issue on the western line it was the bridges due to the weight of the H class locomotives. I don't think a big 4-8-4 would go around sharper curves than a pacific loco like the S class. The development of the H class was to reduce the need to double head locos on the Overland passenger train.

aww i was looking forward to a video on V56 ;)

Heavy harry is cool, but 520 class is the absolute goat 😤😤🐐

A great pity that "Heavy Harry" wasn't preserved in running order for heritage trains today.

I think you need to fact check your sources. An eight coupled steam loco the size of the H class has a longer fixed wheel base than the six coupled S class. Therefore the H class is NOT going to negotiate sharper curves than the S class. The H class was designed to haul the Overland to eliminate double heading on the western line however the wooden trestle bridges were of a too light a construction for the H class to maintain passenger train speeds over the bridges. Bridges were not an issue on the N/E line and the big H handled freight traffic even though it was specifically designed for passenger traffic.

until now, its been allocated for restoration and return to service

My Grandfather told me that when H220 was introduced it collided with a platform and had to have new cylinder fitted, is there any evidence of that? I only got to see Heavy Harry from outside as the museum was closed the one and only time I got to Melbourne. 800t is quite a decent effort.

I think the gm/b classes look good...

0:37 tell that to the now defunct WCR who would triple head 3 diesel's on a 5 car service

Can anyone confirm if it's true that the Heavy Harry into active operations just like our K-Classes, the R-Classes and the Na-Classes (Puffing Billy)?

3050km? Not m?

Very interesting, but would be much better without the "music".

The notorious 'Islington bank' might not exist in the state of Victoria. The location you describe goes by another name. Your sacrilegious bastardization of its name is so deeply offensive to this broad gauge gunzel that I had to ring Lifeline, then the paramedics had to come worsening the ambulance ramping situation in this state - all because you can't be bothered taking responsibility for your dyslexic tendencies. Think of the taxpayers, think of the people that really need treatment (rather than crazed Gunzels blocking up the S bend of the health care system). Not happy!

what a disrespectful documentary, smug and not that enjoyable, sorry.
