3D model I created of the largest steam locomotive ever built

In summary, the conversation revolves around a 3D model of the Chesapeake And Ohio Allegheny 1601 steam locomotive. The creator is trying to adjust the lighting to make the images more visible and also add textures to the floor. They mention using quick fur to create grass and share the settings they used. The conversation then shifts to discussing the complexities of printing the model on a 3D printer and the history of steam locomotives, including the UP Big Boy, C&O Allegheny, and PRR Q2. It is mentioned that the Wikipedia articles do not fully do justice to these locomotives and their manufacturers. The conversation ultimately ends with a mention of the heaviest steam locomotive, the J

Here is a 3D model (blender 2.8) I created of the Chesapeake And Ohio Allegheny 1601 steam locomotive, which remains today the largest locomotive ever built.

Can you change the lighting so that the images are more visible?

I thought that was smoke. 😉

Yeah, I'm just looking for a good HDRI, and I also need to texture the floor to make it look like grass or some other natural ground material.

You can use quick fur to create a pretty good grass. This is what I was able to get fairly easily by tweaking the properties a bit.

Here's what settings I used to get it:

Impressive!

I like building (assembling) small (real) models myself, and I have always been impressed by those who have talent and patience to do models from scratch, both real, and as in this case, virtual.

How long did it take to do the model, I wonder?

And can it be printed on a 3D printer, or is it too complicated? I guess one would have to print the individual parts and then assemble it, perhaps?

Thanks!

It took me about a month to complete.

And it's probably far too complex for a 3D print.

A bit of steam locomotive history

UP Big Boy (4-8-8-4) - 4884-2: 772,250 lb (386 tons), total weight with tender 4884-2: 1,208,750 lb
C&O Allegheny (2-6-6-6) - 772,250 lb (386 tons), or about the same as UP's Big Boy
PRR Q2 (4-4-6-4) -

Nominal or design horsepower -
UP Big Boy ~ 7000 hp, typ operation 5,500–6,290 hp (4,100–4,690 kW)
C&O Allegheny ~ 7500 hp, between 6,700 to 6,900 hp (5.0 to 5.1 MW) at about 45 mph (72 km/h) based on a dynamometer car test.
PRR Q2 ~ 8000 hp, 7,987 cylinder horsepower (5,956 kW) on the PRR's static test plant.

Ref: https://en.wikipedia.org/wiki/Union_Pacific_Big_Boy
https://en.wikipedia.org/wiki/2-6-6-6
https://en.wikipedia.org/wiki/Pennsylvania_Railroad_class_Q2

Those Wikipedia articles don't do those locomotives justice.

Big Boys were built by American Locomotive Company (ALCO)
C&Os Alleghenys were built by Lima Locomotive Works (Lima)
PRRs Q2 were built PPR's Altoona Works, Altoona, PA

Perhaps the heaviest steam locomotive was the Jawn Henry (6-6-6-6), steam turbine locomotive operated briefly by Norfolk & Western (N&W). It weighed 818,000 lb (371,000 kg) (409 t), but was rated at 4500 hp. The locomotive was built by Baldwin Locomotive Works (BLW). Baldwin and Lima-Hamilton eventually merged in 1950. Diesels began replacing steam locomotives in the 1930s/1940s, and most steam locomotives were out of service by 1960.
